ZOO 3733C Lecture Notes - Lecture 2: Inferior Vesical Artery, Middle Rectal Artery, Pelvic Splanchnic Nerves
Document Summary
Spongy- pseudostratified or stratified columnar (except near the end is squamous) Blood supply: branches of interal iliac (superior vesical, obturator gluteal, inferior gluteal, inferior vesical (male), vaginal & uterine (female) Inn: sympathetic (inferior hypogastric plexus); parasympathetic (pelvic splanchnic nerve s2-s4) via inferior hypogastric plexus. Blood supply: internal pudenal artery and vaginal artery. Venous drainage: internal pudenal vein and vaginal vein. 4 parts: preprostatic, prostatic, membraneous, and spongy (first 2 in pelvis, last two in perineum) Blood supply: branches of internal iliac artery (inferior vesical, middle rectal, internal pudenal) Venous drainage: vesical vein, middle rectal vein, pudenal vein. Inn: pudenal nerve (voluntary control), sympathetic (inferior hypogastric plexus), parasympathetic (pelvic splanchnic nerve) Glands produce alkaline secretion containing fructose, sugars, proteins, prostaglandins and other things. Blood supply: inferior vesical artery, middle rectal artery. Venous drainage: inferior vesical vein and middle rectal veini. Inn: sympathetic and parasympathetic (pelvic splanchnic nerve s2-s4) Blood supply: inferior vesical artery, middle rectal artery, internal pudenal artery.
