Histology of Tonsils

Veterinary Anatomy

The palatine tonsil is an egg-shaped mass, which bulges into the oral cavity. The oral surface is covered by stratified squamous epithelium. The epithelium passes down into the crypts in the substance of tonsil. Between the crypts the masses of dense. lymphoid tissue arranged in folds containing the individuals follicles. At intervals, between folds of lymphatic

These divide the organ into interconnected lobule consists of vesicles of varying sizes called thyroid follicles. In young animals they are smaller than in adult. Between follicles there is fine connective tissue fibres, which contain many

The capsule is fibroelastic and from the capsule, tough connective tissue septa containing elastic fibres, smooth muscle and adipose tissue enter the gland and separate the gland into lobes and lobules. The amount of inter lobular connective tissue varies considerably with the functional status of the gland,

Veterinary Anatomy

The wall of the vagina consists of a mucosa, muscularis and fibrosa. The mucosa is non-glandular and is thrown into folds. It is lined by stratified squamous epithelium. The lamina propria consists of loose connective tissue especially rich in elastic fibres. It contains diffuse infiltration of lymphocytes and solitary lymph nodules may also be present.
