Document Summary

Male and female reproductive system purpose to create diversity; understand hormones (types), feedback systems, mitosis and meiosis; female system is cyclical, male system is not. Two tunics tunica vaginalis outer 2 layered, derived from peritoneal membrane of the abdominal pelvic cavity; tunica albuginea fibrous capsule of testis (white coat), septal extensions divide each testis into 250-300 wedge-shaped lobules. Pathway of sperm production seminiferous tubules > tubules rectus (straight tubule) > rete testes. Leydig cells interstitial endocrine cells (surrounding seminiferous tubules, not inside) that produce androgens (testosterone) Blood supply testicular arteries branch from abdominal aorta; testicular veins drain testes and form pampiniform plexus (surrounds each testicular artery) to help with testicular temperature regulation. Spermatic cord bundle up blood and lymph vessels, nerves, vas deferens (single tube after epididymis) Sperm entering epididymis are immature, nonmotile: head caps superior part of testis (receives sperm from efferent ductules, body and tail contain highly coiled duct of epididymis (uncoiled to be 6m)
