Study Notes
Principal Arteries of Anterolateral Abdominal Wall
- Musculophrenic artery originates from the internal thoracic artery and descends along the costal margin, supplying the abdominal wall of the hypochondriac region.
- The abdominal aorta gives rise to arteries that continue beyond the ribs to descend in the abdominal wall between the internal oblique and transversus abdominis, supplying the lateral region.
- The external iliac artery runs superiorly and enters the rectus sheath, supplying the inferior rectus abdominis and the medial part of the anterolateral abdominal wall.
- The arterial supply to the esophagus, stomach, duodenum, liver, gallbladder, pancreas, and spleen includes the celiac trunk, left gastric, splenic, and common hepatic arteries.
- The left gastro-omental artery arises from the splenic artery and supplies the left portion of the greater curvature of the stomach.
- The hepatic artery, a branch of the celiac trunk, supplies the liver, gallbladder, stomach, pancreas, and duodenum.
- The superior mesenteric artery supplies the midgut-derived gastrointestinal tract, including the jejunum, ileum, transverse colon, and ascending colon.
- The inferior mesenteric artery, originating from the abdominal aorta, supplies the distal part of the large intestine, including the descending colon, sigmoid colon, and rectum.
- The autonomic innervation of the abdominal viscera involves splanchnic nerves that carry sympathetic and parasympathetic fibers from their origin to their destination.
- The splanchnic nerves are part of the autonomic nervous system and carry different fiber types, including sympathetic and parasympathetic fibers.
- These splanchnic nerves originate from specific levels of the spinal cord and have destinations in the abdominal viscera, playing a crucial role in the autonomic regulation of abdominal organs.
- Understanding the principal arteries and autonomic innervation of the anterolateral abdominal wall is vital for comprehending the vascular supply and neural regulation of the abdominal organs.
