Document Summary

Ascends out of scrotum: scrotum : supporting structure for the testes. Consists of a sac of loose skin and superficial fascia that hangs from the root of the penis. Location and contraction of muscle fibers (dartos and cremaster muscles) regulates the testicular temp to that required for sperm production (2-3 degrees below the core temp) Contractions of this muscles in the cold causes the testes to move toward body; in heat = the opposite. 2: development of libido, spermatogenesis, spermatozoa: produced in the seminiferous tubules by the stem cells called spermatogonia, a single sperm cell ( several structures that are higly adaptive) Head is mainly nucleus (23 chromosomes) contains acrosome: traveling route: Seminiferous tubules > vas deferens > ejaculatory duct (within prostate gland) > urethra (prostatic, membranous, and penile: at the beginning of puberty, the anterior pituitary increases secretion of the gonadotrophs lh and fsh (stimulates.

CHOOSE ALL THAT APPLY!!! Review your Lecture note packet on the Male Reproductive Anatomy. Read the following statements - and select all statements that are FALSE (hint: there are 4 FALSE answers in this question!)

		Testes - The 2 major functions of the testes are the produce spermatozoa and produce androgen hormones (testosterone)
		Testes - The nurse cells or sustentacular cells produce testosterone
		Epididymis - The epididymis has 3 regions - a head, body and a tail.
		Ductus (vas) Deferens - The extended portion of the ductus (vas) deferens as it nears the prostate gland is called the spermatic cord.
		Ejaculatory Duct - the ejaculatory duct passes through the prostate gland.
		Male Reproductive Glands - The prostate gland produces the majority of the volume of semen fluid.
		Male Reproductive Glands - The seminal vesicle produces fluids that help nourish the sperm, stimulates smooth muscle contraction and forms a temporary clost in the female's vagina.
		Male Reproductive Glands - The bulbourethral glands secrete a thick, alkaline mucus that helps neutralize any urinary acids that may harm the spermatozoa.
		Spermatozoa - The middle piece of the spermatozoa contains mitochondria and geneteic material in it.
		Spermatozoa - The head of the spermatozoa contains an acrosomal cap that contains enzymes that help during fertilization.
