SURGICAL ANATOMICAL APPROACH OF THE ABDOMEN IN THE GOAT

Abstract

The present work carried out on clinically healthy twenty Egyptian Baladi goats of the different age and weight from both sexes for dissection of the abdomen, X-rays with contrast media, cross-sectional anatomy and C.T. images and surgical approach of the abdomen.

The shape of the abdomen in adult goat was bulged laterally and abdominal floor was curved, while compressed laterally and shallower in immature goat. . The abdomen was divided into nine regions which help in toJ?ographic anatomy. The dorsal boundary of the paralumbar fossa extended from 2nd to 6 lumbar transverse processes. The scar of the umbilicus presented at the level 1st or 2nd lumbar vertebra.

The ventrolateral abdominal wall consisted of the skin; sup ;:rficial abdominal fascia which was loose and covered the lateral and ventral abdominal wall. It contained the cutaneous trunci muscle which covered the lateral abdominal wall; cranial and caudal preputial muscle in male and supramarnmary muscle in female, they rested on the ventral abdominal wall; the abdominal tunic was elastic sheet covering the distal half of the lateral thoracic and abdominal walls; external abdominal muscle arose from the 6th rib to last rib and terminated into the line alba, prepubic tendon and tuber coxae its aponeurosis interwoven with aponeurosis of the internal abdominal oblique muscle in epigastric and mesogastric regions; the internal abdominal oblique muscle was fleshy triangular muscle originated from tuber coxae, inguinal ligament and thoracolumbar fascia and terminated in last rib, linea alba, prepubic tendon; the rectus abdominal muscle consisted of 7 segments and 6 tendinous intersections which gave more strength to muscle and the transverse abdominal muscle, divided into costal and lumbar parts which originated from the costal arch, last four ribs and first five lumbar vertebrae and terminated by thin aponeurosis into xiphoid cartilage and linea alba.
