Sex Flashcards

Scrotum

Contains the testes; regulates temperature to optimize sperm production (94 F/ 34 C)

Duct system

accessory structures that form the ducts that carries sperm from testes to external environment

Epididymis

Located on the superior & posterolateral area of the testes; site where immature sperm cells complete maturation process

Ductus deferense/ Vas deferens (sperm duct)

Along with blood vessels & nerves, they are enclosed in collective tissue sheath called spermatic cord; connects the epididymis to ejaculatory duct at ampulla

Ejaculatory duct

propels sperm thru prostate gland to urethra during ejaculation

Urethra

Runs the length of penis, common path of both the urinary & reproductive system; has 3 parts (prostatic intermediate part (membranous), and spongy)

Prostate gland

Inferior to bladder, encircles & secretes milky fluid into urethra to activate sperm

Posterior to bladder, joins ductus deference to form ejaculatory dict; produces alkaline secretion containing fructose & other nutrients which supplies energy to sperm cells or promotes fertilization; produces 60% of seminal fluid

Bulbourethral glands

Inferior to prostate; produces thick, clear, alkaline mucus that drains into membranous urethra (washes out urine during ejaculation of semen (sperm & seminal fluid)

Seminiferous tubules

Site of sperm production; interstitial cells between tubules produce testosterone

Rete testis

Carries sperm from seminiferous tubules to epididymis

Endometrium

Interior layer composed of a functional layer (stratum functionalis) that is formed by basal layer/stratum basalis. The functional layer is the usual site of egg implantation and is discarded during menses.

Uterine/fallopian tubes

located at superolateral region of uterus extending toward ovaries. Distal end closest to ovaries have fimbriae finger-like projections, ampulla is the widest, longest portion, isthmus located medially and is narrow with thick-walled; uterine tube is the usual site of egg fertilization by sperm
