Describe the Testis' in detail with its histology.
Answers
The parenchyma of the testicle is divided into lobules by loose connective tissue bands (septuli testes). These lobules are composed of tubules lined by stratified epithelium composed of maturing germ cells (spermatogonia, spermatocytes, spermatids and spermatozoa) and Sertoli cells.
Answe
The parenchyma of the testicle is divided into lobules by loose connective tissue bands (septuli testes). These lobules are composed of tubules lined by stratified epithelium composed of maturing germ cells (spermatogonia, spermatocytes, spermatids and spermatozoa) and Sertoli cells. These tubules are supported by a basement membrane which contains fibroblasts and myofibroblasts. The Sertoli cells are triangular or oval in shape with a prominent nucleolus and fine chromatin. These tubules (seminiferous tubules) constitute the exocrine portion of the testes. The maturing germ cells are stratified so that the spermatogonia constitute the basilar compartments closest to the basement membrane. The spermatocytes, spermatids and spermatozoa constitute the next layer or the apical compartment with the spermatocytes adjacent to the basilar compartment and the spermatozoa closest to the lumen.
