Everything about The Midgut totally explained
The
midgut is the portion of the
embryo from which most of the
intestines are derived. After it bends around the
superior mesenteric artery, it's called the "midgut loop". It originates from the
foregut at the opening of the
bile duct into the
duodenum and continues through the small intestine and much of the large intestine until the transition to the
hindgut about two-thirds of the way through the transverse colon.
Structures in the adult midgut
Vascular, lymphatics and innervation
Arterial supply to the midgut is from the
superior mesenteric artery, an unpaired branch of the
aorta. Venous drainage is to the
portal venous system. Lymph from the midgut drains to prevertebral
superior mesenteric nodes located at the origin of the superior mesenteric artery from the aorta. Portal drainage carries all non-lipid nutrients from digestion to the liver for processing and detoxification, while lymphatic drainage carries fatty chyle to the
cisterna chyli. Autonomic innervation of the midgut is from the
superior mesenteric plexus.
Clinical notes
Malrotation of the midgut during development can lead to volvulus.
Pain in the midgut is referred to the umbilical region (around the umbilicus (belly button)).Further Information
