The Histological Study of the Ileum in the Caucasian Squirrel Sciurus anomalus

The current study was designed to identify the histological composition of ileum in Caucasian squirrel Sciurus anomalus. Ten adult squirrels were used for present study. Animals anesthetized, anatomized, fixed specimens 10% formalin solution, and conducted a series staining techniques. consists four main tunicae represented by mucosa, submucosa, muscularis, serosa. tunica mucosa three secondary layers: epithelial lining layer, lamina propria, muscularis mucosa. comprises simple columnar tissue composed cells goblet cells. propria contains straight tubular glands called intestinal or crypt Lieberkuhn. is very thin, single layer smooth muscle fibers arranged circularly. submucosa dense connective tissue, while appears two layers fibers. serosa loose that covered mesothelium.
