MORPHOLOGICAL AND HISTOLOGICAL STUDIES OFAPPENDIX IN LOCAL RABBITS

Abstract

The macroscopical and microscopical of appendix were investigation of ten adult wild rabbits that collected from AL-Hilla city Markets.and studied appendix it is considered as one of the members of the digelstive tract of mammals category as the rabbits Through this experimental period which continued nearly a month from(5/3/2016 – 5/4/2016) the appendix was recognized the shape ,position,dimensions and studied some characteristics of rabbit (Body weight ,appendix weight ,appendix length ,appendix thickness)The correlation coefficient used in this studyBetween the traits, as observed no correlation between body weight and appendix weight while observed a strong correlation between the length of appendix with body weight and thickness of appendix with body weight . and analayzed results by Completely randomized design to compared the effect of animal sex(C.R.D) on the studied features means. Showed on significant differences in (P≤0.05).in each all body weight in male and female(1920±1800) , appendix length(8.58±8.06), appendix weight(5.236±7.754), appendix thickness(0.60±0.62).Were studied Anatomically the appendix is ablind-ended tube located at the junction of the small and the large intestine. The average length ranging from 6_9 about 1cm approximately longest in males than females. Microscopically:the appendix in rabbits consist of four layer it is from inside to outside (mucosa, sub mucosa, musculars, serosa) with epithelial contain many of goblet cells and lymphocyte and enteroendocrinecytes in the lamina propria of the mucosa layer.where the tissue lining the mucosa layer from type simple columnar epithelial tissue punctuated many of the goblet cells (glandular unicellular epithelial gland )and contain enteroendocrinecyte which responsible for absorbition and secration functions.
