pelvic cavity, floor, roof and the perineum

Question 1

describe where the pelvic cavity is located and what it is continuous with

Answer 1

the pelvic cavity lies within the bony pelvis, between the pelvic inlet and the pelvic outlet. It is continuous with the abdominal cavity

Question 2

describe what is meant by the pelvic floor

Answer 2

the pelvic floor is an internal wall of skeletal muscle, separating the pelvic cavity and perineum

Question 3

what is the perineum

Answer 3

the perineum is the area inferior to the pelvic floor, in between the proximal parts of the lower limbs (little space below pelvic floor)

Question 4

what do openings in the pelvic floor allow

Answer 4

allows for the distal alimentary(digestive), renal and reproductive tracts to pass through

Question 5

what is meant by the pelvic roof

Answer 5

pelvic roof is formed by the parietal(pertaining to walls of organ or cavity) peritoneum

Question 6

parietal peritoneum is

Answer 6

the lining of the abdominal cavity, firmly attached to the walls and draped over the pelvic viscera(area)

Question 7

describe the relationship between the parietal peritoneum, peritoneal cavity and abdominal cavity

Answer 7

the parietal peritoneum lines the walls of the pelvic viscera and abdominal cavity, the peritoneal cavity lies just above the peritoneum and below the abdominal cavity

Question 8

describe what the vesico-uterine pouch and pouch of Douglas(rectouterine) are and what their clinical significance is

Answer 8

they are pouches caused by the draping of the peritoneum over the bladder, uterus and rectum. the vesico-uterine lies between the bladder and uterus, the Douglas lies between the rectum and uterus. They catch any excess fluid and if this gets too much it can be removed.
