Veterinary Splanchnology and Applied Anotomy

ABOMASUM

• The abomasum is an elongated sac, which lies on the abdominal floor from the xiphoid cartilage backwards
• The cranial blind end is at the xiphoid region in relation with the reticulum
• The body extends back between the ventral sac of rumen and the omasum and turns to the right behind the omasum
• It is constricted about the middle forming an cranial larger part and a caudal pear shaped smaller part
• The pyloric part inclines dorsally and joins the duodenum at the ventral part of the 10th rib
• The parietal surface is in contact with the abdominal floor. The visceral surface is related to the rumen and omasum
• The greater curvature gives attachment to the superficial part of the greater omentum
• The lesser curvature is related to the greater curvature of the omasum (View image)
