mesentery definition

hello again everyone! this is matt from kenhub, and in this tutorial,we will be looking at an anatomical space of the male pelvic cavity – the rectovesicalpouch. the rectovesical pouch in green is an anatomicalspace only found in the male pelvis. it lies between the rectum here and the urinarybladder here. the pelvic cavity is home to these and otherinfraperitoneal organs. they mostly lie inferior to the peritoneumwhich envelops the area here. in the posterior region of the male pelviccavity, a single layer of the peritoneum is reflected from the superior posterior surfaceof the urinary bladder onto the anterior wall

of the middle to upper portions of the rectum. this forms a recess which is continuous withthe peritoneal cavity – the rectovesical pouch. the rectovesical pouch, as a continuationof the peritoneal cavity, is lined by peritoneum. it is also the deepest part of the peritonealcavity. the rectovesical pouch along with the otherpelvic spaces provide the infraperitoneal organs with some degree of mobility as wellas providing route for the spread of inflammation or posttraumatic hemorrhage. for comparison, in the female pelvis, thereis no rectovesical pouch because of the presence

of the uterus. instead, there is a vesicouterine pouch betweenthe uterus and urinary bladder and the rectouterine pouch between the uterus and the rectum. this video is more fun than reading a textbook,right? if you want more videos, interactive quizzes,articles, and an atlas of human anatomy, click on the “take me to kenhub” button. it is time to say goodbye to your old textbooksand say hello to your new anatomy learning partner, kenhub! see you there!
