Internal iliac artery
Internal Iliac Artery
The Internal Iliac Artery (pronunciation: /ɪnˈtɜːrnəl aɪˈliːək ˈɑːrtəri/), also known as the Hypogastric Artery, is a major blood vessel in the pelvis. It originates from the common iliac artery, where it splits into the internal and external iliac artery.
Etymology
The term "iliac" is derived from the Latin "ilium," referring to the hip bone. The prefix "internal" is used to differentiate this artery from the external iliac artery, with "internal" indicating that this artery supplies blood to the organs within the pelvis.
Anatomy
The internal iliac artery supplies blood to the pelvic organs, gluteal region, and medial compartment of the thigh. It is divided into an anterior and a posterior division, each giving rise to several branches. The anterior division includes the umbilical artery, inferior vesical artery, middle rectal artery, uterine artery, vaginal artery, obturator artery, internal pudendal artery, and inferior gluteal artery. The posterior division includes the iliolumbar artery, lateral sacral artery, and superior gluteal artery.
