0:35hello everyone this is dr. Cadell
0:37boondock professor of anatomy and the
0:39neuroscience Mansoura university egypt
0:42today i will talk about the anatomy of
0:45the urinary bladder and the urethra so I
0:49will start with the urinary bladder I
0:51will talk about the position in the
0:53adult and in the children I will talk
0:56about the shape which is pyramidal okay
0:59and since a peritoneal covering in males
1:03and the females and also the relations
1:05and the tribe own ends arterial supply
1:09of the urinary bladder start with the
1:13position and the shape of the urinary
1:15bladder this is a Ranieri bladder okay
1:18this is the urinary bladder so okay
1:21position and shape the position of the
1:25urinary bladder in the adult and in the
1:27children in the adult if it is empty it
1:32lies in the anterior part of the pelvis
1:35if it is distended then it will expand
1:39the why behind the anterior abdominal
1:42wall okay in a children it is abdominal
1:46organ due to the small size of the
1:50pelvis okay since the shape is pyramidal
1:53pyramidal it has FX which is interior
1:57angle this is ABC this is ables it has
2:01if is okay this is the bees of the
2:04pyramid it has neck which is the
2:08inferior angle this is Anna cozy Ranieri
2:11bladder and it has three surfaces okay
2:15to post through superior angles for the
2:18entrance of the ureter and three
2:21surfaces upper surface and the two
2:23inferior lateral surfaces so the urinary
2:26bladder is pyramidal in shape it has its
2:28interior angle it has bees okay it has
2:32nectar it is the inferior angle it has
2:35to push through superior angles for the
2:38entrance of the ureter and
2:40has three surfaces upper surface and two
2:44inferior lateral surfaces reportin
2:48separate Ania covering of the urinary
2:50bladder in the mill and in the female in
2:53the mill
2:54upper surface and the upper part of the
2:58base of the urinary bladder it is
3:00separated this upper part of the B's is
3:04separated from the rectum by Zurich to
3:06recycle pouch this pouch in the female
3:10it's covered only on the upper surface
3:13the upper surface is only covered with
3:15peritoneum and it is separated from the
3:18uterus by the uterine muscle pouch super
3:23retinol covering in the mill upper
3:25surface and upper part of the base in
3:27the female upper surface only there is
3:34the relations of the urinary bladder in
3:36the mill this is a male urinary bladder
3:38so certifies Avox this is Able's the
3:43apex lies behind upper border of the
3:46pubic symphysis it is connected with
3:48some lightness by the median on black
3:51ligament which is obliterated Eureka so
3:55the zeebee zeebee the upper part of the
4:00beast is related to erect over psychical
4:03pouch separating the upper part of the
4:06beast from the rectum and the lower part
4:10of the bees is related to the seminal
4:12vesicles and the vast difference
4:15separating the base of the urinary
4:17bladder from the rectum so the base of
4:19the urinary bladder is related to upper
4:22part Rick to OVA cycle pouch
4:25lower part seminal vesicles and the vas
4:27deferens
4:28then the neck of the urinary bladder the
4:31neck of the urinary bladder
4:33rests on the prostate gland and it is
4:36connected with the pubes of the pubis by
4:39pupil prosthetic
4:41ligaments there is a three surfaces
4:45upper surface related to small intestine
4:47okay and then to inferior lateral
4:49surfaces will describe them
4:52okay this is the base of the urinary
4:55bladder in the mill the upper part of
4:57CBS is related to Zurich to recycle
5:00pouch the lower part of CBS is related
5:03to the seminal vesicles and was a
5:05differential this one was different and
5:08this is the other was difference
5:10regarding the relations in the female
5:13this is the uterus okay fundus body and
5:17cervix and this is the vagina so started
5:21by the Avox the image is similar to that
5:24of the mill this Able's
5:27is connected to samba lightest by the
5:28median embolic indignant which is
5:31obliterated
5:32Eureka's and the Able's lies behind the
5:35upper border of the pubic symphysis the
5:38piece of the urinary bladder in the
5:40female is related to the vagina and the
5:43service of the uterus okay
5:45the NIP of the urinary bladder in the
5:48female is continuous with the urethra
5:51and the sons upper surface is related to
5:54small intestine in this pouch which is
5:57the utero for psychical pouch zena's the
6:01three surfaces upper surface and to
6:05infer lateral surfaces this is the
6:07inferior lateral surface it is divided
6:09into three zones the anterior part this
6:13is the anterior part is related to the
6:15true pubic bed effect later google fact
6:19the ends of the 0 part is related to two
6:22muscles the upper part is related to
6:24operator interest and the lower part is
6:27related to elevator in high so the
6:30inferior lateral surface the anterior
6:32part is related to the retro pubic fat
6:35and the posterior part is related to
6:37operator internals above and delimiter
6:40ni below this is at Reagan of the
6:45urinary bladder the travel of the
6:48urinary bladder is triangular area on
6:52the inner surface of the B is the base
6:57of the Trigon is formed by the enter
6:59ureteric red this is the entirety
7:02Rudraksha between the two urine theory
7:06orifices the apex of the tree bone is
7:10the internal urethral orifice the mucous
7:14membrane of the treble as you see is
7:17smooth
7:18due to the great elasticity of the
7:21treble regarding the arterial supply of
7:27the urinary bladder the urinary bladder
7:30is supplied by recycle or Trece this is
7:34the internal iliac artery the internet
7:37iliac artery gives it two branches
7:39umbilical artery and inferior cycle or
7:42three so we have three or tresses two in
7:46the mail and the two in the female okay
7:49so here are the cycle or tree this
7:52superior recycle artery in males and in
7:55females and then in fear of a cycle or
7:58tree in the mill and vagina or tree in
8:03the female superior physical or tree
8:06okay
8:07it's a branch from some oracle artery in
8:09fear of a cycle or tree is a branch from
8:12the internal iliac artery and the vagina
8:15or three is branch from the internal
8:17iliac artery just reminding view of the
8:20distribution of the inferior mosaic
8:22alert this inferior physical artery in
8:25Zamir it supplies the urinary bladder it
8:28supplies the seminal vesicle was
8:30difference and the porosity
8:32all these structures are supplied by the
8:35inferior recycle art so arterial supply
8:38of the urinary bladder in the mill
8:40superior recycle art reforms on belated
8:43in fear of a cycle artery from the
8:45internal iliac blood supply of the
8:47urinary bladder in the female severe
8:51recital or three forums on volatile
8:52artery and the vaginal or three from the
8:55internal iliac artery okay just let us
8:59have a summary on this a urinary bladder
9:01okay this is a urinary bladder so
9:04position in a lot and in children in
9:08adult if it is empty it lies in the
9:13anterior part of the pelvis if it is
9:15full it will expand the upward we
9:18hands anterior abdominal wall okay in a
9:21children it is it is abdominal organ due
9:25to the small size of the pelvis Zn it is
9:28the shape is pyramidal in shape remedy
9:31in shape has a beats base to push
9:36through superior angles neck and the
9:39three surfaces peritoneal covering in
9:41the mill upper surface and upper part of
9:43the base in the female upper surface
9:46only and then Relations of the urinary
9:49bladder okay
9:51Epic's this it's behind the pubic
9:55symphysis okay and it is connected to
9:57the Americas by the medium on bollocky
10:00ligament the bees in the middle the
10:03upper part in the mill is related to the
10:06direct opposite approach the lower part
10:08is related to similar vesicles and was a
10:10differential okay in the female it is
10:13related to the vagina the in sanik in
10:17the mill it rests on the prostate gland
10:19and it is connected with the pubis by
10:22the pupil prosthetic ligament in the
10:25female the base of the urinary bladder
10:27is the neck of the urinary bladder in
10:30the female is continuous with the
10:32urethra and is connected with the pubis
10:35by booboo recycle ligament upper surface
10:39small intestine okay and
10:44inferior lateral surface related is
10:47anterior part Ritter booby-trapped the
10:49posterior part of curator internals and
10:52delimiter in our arterial supply sari or
10:55tresses okay severe of a cycle or three
10:57in males and the females from symbolical
11:00artery in fear of a cycle artery in the
11:02mill and the vaginal artery in the
11:04female in fear of a cycle and wash renal
11:06or branches from the internal iliac
11:09artery so finishes a urinary bladder let
11:14us have a look at the urethra this is
11:18the male urethra the male urethra is
11:21about 20 centimeters long it is is
11:25shaped okay it is divided into four
11:29parts the first part is called the pre
11:32prosthetic part this pre prosthetic part
11:36lies between the prostate and the senate
11:38of the urinary bladder and this is pre
11:41prosthetic part is surrounded by the
11:44internal urethral issue and Patera
11:48second part is the prosthetic part this
11:51is the prosthetic part of the urethra it
11:53is the widest part it lies inside the
11:56prostate gland it receives the open end
11:59of a generator ducts and the prosthetic
12:02utricle and this is the third part
12:05membranous part this membranous part
12:08lies in the deep peroneal pouch and it
12:11is surrounded by the external urethral
12:14sphincter zenith of all support this one
12:19is a spongy part this is one g part lies
12:22in the bulb of the penis and M corpus
12:25spongiosum
12:27this is full G part has to do
12:30allegations this is the first validation
12:32bulb or fossa and this is the second
12:35dilatation navicular fossa so bulb or
12:39four saw in the bulb and the navicular
12:42fossa in the grains this spongy part
12:48receives the open end of the bulb Oh
12:50uracil glands so they may be Ora is 20
12:53centimeters around it is easy shape the
12:55structure
12:56okay it is divided into four parts 3%
12:59part prosthetic part membranous part is
13:03on Shabbat the people set apart between
13:06the prostate and the neck of the urinary
13:08bladder it is surrounded by the internal
13:10urethral is Schumpeter prosthetic part
13:13inside the prostate it is the most it is
13:16the widest part it receives it the open
13:19end of prosthetic utricle and to
13:23ejaculatory ducts
13:25then the membranous part it lies in the
13:27deep peroneal pouch and it is surrounded
13:29by the external urethral sphincter this
13:33is the spoon actually the membranous
13:35part is the shortest is the narrowest
13:37part then the spongy part
13:40this is the spongy part is spongy part
13:42in the bulb of the penis and then corpus
13:45spongiosum it has two the radiations
13:47bulb or fossa and the navicular fossa
13:50and it receives his opening of the Volvo
13:54urethral event
13:56okay so the prostatic part is the first
14:01part second part is the prosthetic part
14:04and the third part is a membranous part
14:07the proposed settlement is surrounded by
14:11the internal urethral sphincter the
14:16prosthetic part receives the opening of
14:18okay so the proportional part is
14:21surrounded by the internal urethral
14:23sphincter is a prosthetic part of course
14:26receives the opening of the ducts of the
14:29prostate gland okay and it receives the
14:33opening of prosthetic ear Terkel in the
14:35middle and ejaculatory ducts
14:39it has a revision of the seminal
14:41colliculus this elevation in the
14:44posterior wall of the prostatic urethra
14:47called the seminal colliculus and the
14:49third part is the membranous part it is
14:52surrounded by the external urethral
14:55sphincter so actually the urethra has
14:58two senators internal urethral sphincter
15:00and the external urethral sphincter so
15:04let us have a comparison between the
15:07three parts of the urethra
15:10prosthetic membranes and de-spawn she
15:13started by zillions of each part
15:16prosthetic part is one-inch membranous
15:19part is heaven Elsa and the spongy part
15:22six inches longer the prosthetic part
15:26rise and the prospect membranous part in
15:28the deep peroneal pouch a spongy part in
15:31the bulb of the penis and the
15:33corresponds is on the prosthetic part is
15:37the widest part the membranous part is
15:40the narrowest part the spongy part has
15:43to dilatations bulb or fossa in Sapulpa
15:46navicular fossa in the grains the
15:49prosthetic part receives the openings of
15:52ejaculatory ducts and the prostatic
15:55utricle membranous part is surrounded by
15:58external urethral sphincter and the
16:01spongy part receives its openings of
16:03Volvo uracil
16:05greens urethral sphincter or two
16:11internal urethral sphincter and the
16:14external urethral sphincter
16:17here is each one internal urethral
16:21sphincter lies between the neck of the
16:23urinary bladder and the prostate the
16:26external urethral sphincter
16:28it lies in the deep peroneal pouch the
16:33internal urethral sphincter surrounds
16:36the prosthetic part the external
16:39urethral sphincter
16:40surrounds the membranous part the
16:44internal urethral sphincter is formed of
16:47smooth muscles so it is supplied by the
16:50autonomic nervous the external urethral
16:53sphincter is formed by little muscle
16:56fibers so it is supplied by somatic
16:58nervous which is the pudendal nerve what
17:01is the function of each one internal
17:04original resurrector is involuntary
17:06Centre for the urinary bladder
17:09Oh actually for the bladder neck it's
17:12eternal uracil strenghten is voluntary
17:16sphincter for the urethra so we have
17:19internal structure and the external
17:22circuit
17:23internal sphincter between the neck of
17:25the bladder and the urethra external
17:27sphincter in the deep perennial pouch
17:29internal sphincter surrounds the pre
17:32prosthetic part external sphincter
17:34surrounds the membranous part internal
17:38structure is formed of smooth muscle
17:40fibers that's why it is supplied by
17:44autonomic nervous if the journalist from
17:46Qatar is format of a little muscle
17:49fibers that's why it's supplied by the
17:51pudendal nerve the internal sphincter is
17:57involuntary sphincter for the urinary
18:00bladder the external sphincter is
18:03voluntary and return for the urethra
18:05then the meal use a female urethra this
18:09is the familiarise are embedded in the
18:12anterior rulers of China actually the
18:14familiar is four centimeters longer okay
18:18it is related to the anterior role of
18:21the vagina
18:22and it opens in the vestibule
18:25this is the vestibule so this is the
18:29original orifice opens in the vestibule
18:31four centimeters embedded in the
18:34anterior role of the vagina and also it
18:36is surrounded by external in an external
18:40urethral sphincter
18:42external urethral Center in the deep
18:44Reynold pouch and thank you very much
18:48best wishes and the word luck and see
18:51you later
