Which segment of the colon originates at the right colic flexure?

The right colic flexure or hepatic flexure (as it is next to the liver) is the sharp bend between the ascending colon and the transverse colon. The hepatic flexure lies in the right upper quadrant of the human abdomen. It receives blood supply from the superior mesenteric artery.

What quadrant is the left colic flexure in?

left upper quadrant
Left colic flexure (or splenic flexure) is the bend in the large intestine in the left upper quadrant of the abdomen as the transverse colon continues as the descending colon.

Is the hepatic flexure retroperitoneal?

The ascending colon runs superiorly on the right side of the abdomen from the right iliac fossa to the right lobe of the liver. At this point, it makes a left turn at the right colic flexure (hepatic flexure). Ascending colon is a retroperitoneal organ and has paracolic gutters on either side.

What is the left flexure of the colon called?

Your colon has two flexures: one on the right side and one on the left. The splenic flexure is called that because it’s near your spleen, but sometimes it’s called the left colic flexure because it’s on the left side of your body. Your small intestine meets your colon in your lower right abdomen.

Where is the retroperitoneal colon located in the human body?

It is retroperitoneal in the majority of individuals, but is located anteriorly to the left kidney, passing over its lateral border. When the colon begins to turn medially, it becomes the sigmoid colon.

Where does the descending colon and transverse colon come from?

Distal 1/3 of the transverse colon, descending colon and sigmoid colon – derived from the hindgut. As a general rule, midgut-derived structures are supplied by the superior mesenteric artery, and hindgut-derived structures by the inferior mesenteric artery.

Where does the transverse colon attach to the omental bursa?

The transverse colon is intraperitoneal. A peritoneal mesentery ( transverse mesocolon) attaches it to the posterior wall of the omental bursa. This forms two abdominal compartments called supracolic and infracolic compartments. The descending colon extends between the left colic flexure and sigmoid colon.

How is the ascending colon connected to the abdominal wall?

It ends at the right colic (hepatic) flexure. The ascending colon is retroperitoneal and it is connected to the posterior abdominal wall by the Toldt’s fascia. A deep vertical groove or recess (right paracolic gutter) lies between the ascending colon and the lateral abdominal wall.
