The ascending colon is smaller in calibre than the cecum from where it starts. It passes upward, opposite the colic valve, to the under surface of the right lobe of the liver, on the right of the gall-bladder, where it is lodged in a shallow depression, the colic impression; here it bends abruptly forward and to the left, forming the right colic flexure (hepatic) where it becomes the ...
In the colon, for example, the muscular layer is much thicker because the faeces are large and heavy and require more force to push along. The outer longitudinal layer of the colon thins out into 3 discontinuous longitudinal bands, known as taeniae coli (bands of the colon). This is one of the 3 features helping to distinguish between the large ...
Parasympathetic innervation to the ascending colon is supplied by the vagus nerve. Sympathetic innervation is supplied by the splanchnic nerves that join the celiac ganglia . Most of the digestive tract is innervated by the two large celiac ganglia, with the upper part of each ganglion joined by the greater splanchnic nerve and the lower parts ...
This nerve goes on to innervate the jejunum, the ileum, the ascending colon and the transverse colon. While the sympathetic input of the midgut is innervated by the sympathetic nerves of the thorax, parasympathetic innervation is done by the vagus nerve , which travels along the plexuses that arise from the anterior and posterior vagal trunks ...
The ascending colon is the first of four main sections of the large intestine. It is connected to the small intestine by a section of bowel called the cecum. The ascending colon runs upwards through the abdominal cavity toward the transverse colon for approximately eight inches (20 cm).
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.
The mesentery associated with the ascending colon and descending colon is resorbed, bringing these parts of the colon into close contact with the body wall." [ 9 ] In The Developing Human , the author states, "the mesentery of the ascending colon fuses with the parietal peritoneum on this wall and disappears; consequently the ascending colon ...
The longest part of the large intestine is the colon whose main function is to absorb water and salts. [21] The large intestine begins at the cecum, where the appendix is located. This is also the start of the colon as the ascending colon in the back wall of the abdomen.
