Document Summary
Spermatic cord- cremaster muscle, ductus deferens, pampiniform plexus, testicular artery. Testicular tubules house sertoli cells and all germ cells. Efferent ducts epididymis ductus deferens ampulla urethra. Loss of tubule immune privilege(blood/testis barrier) results in loss of meiotic and post-meiotic germ cells. Loss of hormone signaling results in loss of post-meiotic germ cells. Pampiniform plexus and scrotum- temperature control of testis. Loss of temp homeostasis results in loss of all germ cells. The secretory layer of the uterine wall is the endometrium. Primordial follicles- most immature, squamous cells, stimulate cell division in genital ridge. Granulosa cells direct oocyte development, are avascular, and perform steroidogenesis. Mesometrium provides connective tissue support for the uterus. 2 everything, no uterine body- marsupials, forked penis. 2 cervix and uterine horn, 1 vagina- rabbits. Small uterine body- poor to moderately formed. Avain oocyte- germinal disk(sperm enters), yolk(energy) and vitelline membrane(zona pellucida) Anterior pituitary- derived from ectoderm in roof of the mouth, rathke"s pouch.
