ZOO 3733C Study Guide - Midterm Guide: Deep Inguinal Ring, Abdominal External Oblique Muscle, Genitofemoral Nerve
Document Summary
Abdominopelvic cavity: the area between the thoracic diaphragm and the pelvic diaphragm: the upper part is considered the abdominal cavity and extends as high as the fourth intercostal space. Caudal part: continued in male into the spermatic cord as the cremaster muscle. compress abdominal viscera, Afferent limb: femoral branch of genitofemoral nerve and or ilioinguinal n.
