Document Summary
Highly coiled tubes packed into tunica albuginea (fibrous envelope) Carries sperm from seminiferous tubules to efferent ducts. Network of delicate tubulates located in hilum of testicle. Connect rete testis with initial section of epididymis. When sexually aroused, mucous-like fluid called pre-ejaculate is produced. Sperm maturation and storage occurs here before passing to vas deferens. Short duct from base of penis to spongy urethra. Secretory mucous protects urethra and serves as lubricant during sexual intercourse. Supplies extensive collateral oxygenated blood to pelvic organs. Turns into femoral artery in the thigh. Tissue that engorges when filled with blood. Expansion of tissue restricts venous blood flow thus, maintaining erection. Prevents urethra from pinching closed during erection. Maintains a channel for semen during ejaculation. Three primary erectile tissue bodies: corpus cavernosum (paired, corpus spongiosum. Produces seminal fluid necessary to carry sperm. Secretes alkaline w/ fructose (semen) to supply spermatozoa with energy. Consists of a series of muscle and fascial layers.
