Abstract | ||
The tongue of goose was analyzed macroscopically and by light microscope . Macroscopic analysis showed a clear median longitudinal groove along the anterior to posterior half of tongue. The root of tongue have central circular depression . Cylindrical lingual papillae were detected on sides of tongue in addition to conical papillae found in root of goose tongue . Also the macroscopic studies appeared elongated shape with rounded tip about 7 cm in length . The width of anterior part 1.1 cm changing to the posterior region to 1.3cm. Histological analysis Showed three zone anterior , middle , and posterior parts . The anterior part covered externally by keratinized non cellular stratified sequamous epithelial tissue , deep to it lamina properia with skeletal cells and phagocytes with collagen fibers intermingled with skeletal muscle . under skeletal muscle the adventitia consist of adipose tissue . while the middle part consist of stratified sequamous epithelial tissue more cellular than anterior , the lamina properia consist of skeletal muscle intermingled with few collagen fiber . The posterior parts consist of stratified sequamous epithelium but there are crypt formation . Lamina properia of posterior part contain thick skeletal muscle layer and more of salivary glands . Also we find that the posterior part contain cartilage in between adipose tissue under lamina properia . | ||
