Another anastomotic branch may also supply the uterus from anastomosis of these two arteries. Afferent nerves supplying the uterus are T11 and T12. Sympathetic supply is from the hypogastric plexus and the ovarian ...
The pouch on the other side of the uterus near to the anterior fornix is the vesicouterine pouch. After passing over the fundus of the uterus, the peritoneum extends inferiorly along the entire posterior aspect of the uterus, reaching the posterior vaginal wall before reflecting superior-ward onto the anterior aspect of the rectal ampulla (i.e ...
In place of the uterus and vagina, non-mammal vertebrate groups have an unmodified oviduct leading directly to a cloaca, which is a shared exit-hole for gametes, urine, and feces. Monotremes (i.e. platypus and echidnas ), a group of egg-laying mammals, also lack a uterus, vagina, and vulva, and in that respect have a reproductive system ...
