Veterinary Anatomy

Wall of the uterus is madeup of a mucosa, muscularis and serosa. Muscosa or Endometrium: bears a columnar epithelium. The cells are secretory in type. Lamina propria contains uterine glands. These glands are simple branched tubular glands which are coiled towards their ends. The connective tissue stroma resembling mesenchyme or embryonal connective tissue surrounds the glands. Epithelium of […]

Uterine tube or Fallopian tube Wall of the oviduct is composed of a mucosa, muscularis and serosa. Mucosa bears a columnar epithelium, parts of which are psuedostratified in the rurminants. The epithelium contains columnar cells some of which are ciliated, whereas others are not ciliated. The mucosa forms large primary and small secondary folds. The

This histological picture depends on the plane of section and phase of sexual cycle. Ovary can be divided into two zones – cortex (zona parenchymatosa) and medulla (zona vasculosa). It is surrounded by a tunica albuginea which itself is covered by a germinal epithelium. In the young this germinal epithelium is a single layer of cuboidal or columnar cells, which become

The female genital apparatus consists of the ovaries, oviducts, uterus, vagina and vulva. The entire apparatus is in the scene of regularly recurring process of growth and involution which constitutes the sexual cycle, which is interrupted only by pregnancy and old age. Ovary like the testis is a cytogenous gland. It produces the female germ cells –

Penis consists of a body and glands. Body consists of The erectile corpus cavernosum penis, whose two crura are attached to the ischial arch. Corpus cavermosum urethrae or corpus spongiosum penis surrounding urethra muscles. Glans penis forms the tip of penis. Body of penis Consists of the corpora cavernosa, which have a capsule, a system of trabeculae and

Urethra of Male The urethra is a long mucous tube, which extends from the urinary bladder to the glans penis. It consists of pelvic and extrapelvic or penile part. The pelvic part is lined by transitional epithelium. The vas deferens, seminal vesicles, prostate glands are opening into the urethra in its initial part and the ducts of bulbourethral

Accessory genital glands open into the urethra and include seminal vesicles, prostate and bulbourethral or cowper’s glands. Seminal vesicle Seminal vesicle of bull is a thick-walled sacculated tube bent on itself several times in a tortuous manner, to form lobules separated by heavy smooth muscular septa. The capsule and the septa contain abundant plain muscle fibres,

Ductus deferens or Vas deferens has a mucosa, muscularis and fibrosa. The mucosa form longitudinal folds and is lined by pseudostratified columnar cells similar to that of ductus epididymis. But the cells are low and stereocilia shows variable distribution, absent form some cells and present in others. Lamina propria is rich in elastic tissue. Muscularis

Histology of Epididymis Epididymis is a highly convoluted tube to form a solid body so that in section the tube is cut several times. The duct is enveloped by collagenous tunic, which contains circular smooth muscle. The duct has a wide lumen and the mucosa has no folds. The epithelium is pseudostratified columnar ciliated and
