Inferior Mesentric Artery : Origin, Course, Branches, Arterial supply and Clinical aspects

📌𝐅𝐨𝐥𝐥𝐨𝐰 𝐨𝐧 𝐈𝐧𝐬𝐭𝐚𝐠𝐫𝐚𝐦 :-   / drgbhanuprakash   The inferior mesenteric artery (IMA) is one of the three non-paired major splanchnic arteries, in the abdominal cavity, arising from the abdominal aorta and supplying the hindgut. It is the smallest of the three anterior visceral branches of the abdominal aorta. Location Located within the mesentery of the hindgut, passing to the left of the midline. Origin Unpaired vessel from the anterior aspect of the abdominal aorta at the L3 level, at the lower edge of the third part of duodenum. Course The IMA runs obliquely downwards towards the pelvic brim, initially anterior and then to the left of the aorta. After giving off the left colic and sigmoid arteries, it crosses the origin of the left common iliac artery at the sacroiliac joint medial to the ureter, with the inferior mesenteric vein lying between the two. Within the pelvis, it continues along the pelvic wall as the superior rectal artery in the root of the sigmoid mesocolon. Branches left colic artery two to four sigmoid arteries superior rectal artery (terminal branch) Supply splenic flexure of large bowel to the upper two thirds of the rectum Relations anterior: third part of the duodenum posterior: abdominal aorta, left psoas, sympathetic trunk, left common iliac artery, hypogastric nerve lateral (left): inferior mesenteric vein The left colic and sigmoid branches of the IMA cross anterior to the ureter. #inferiormesentericartery #anatomy #anatomyvideos #anatomylecture #anatomyclass #anatomylectures #anatomyusmle #anatomymbbs #anatomyneetpg #usmle #usmlestep1 #usmlevideos #nationalexittest #neetpg #usmlepreparation #mbbs #nationalexitexam #fmge
