Ch.2 Flashcards
penis
ejaculate semen and transport urine from inside the body to outside
penile glans
sexually sensitive area of penis, the tip.
Corona
raised ridge at the base of the penile glans where the tip joins the shaft.
frenulum
area of tissue at the base of the underside of the penile glans, is typically reported to be the most sexually sensitive area of the glans
penile shaft
loose to allow for expansion during erection
foreskin
skin covering penile glans
corpora cavernosa
2 tubes on the top side of the penis
corpus spongiosum
third tube that runs along the underside of the penis
urethra
tube that runs the length of the penis and into the body to carry semen/ urine from the inside to outside of body
scrotum
pouch of 2 layers of skin that hangs below and behind the penis
spermatic cords
2 small muscles move the scrotum and testicles up and down depending on different situations.
testicles
float freely, one in each sac, within the scrotum
gonads
testicles are glands which produce cells for reproduction
testosterone
testicles primary function to manufacture sperm cells and secrete this male sex hormone.
seminiferous tubules
each testicle composed of these seed forming tubes
epididymis
where sperm cells migrate in an immature state. long, narrow structure attached to the back of each testicle. where sperm cells mature and wait to be ejaculated.
vas deferens
each epididymis is attached to this. a tube through which mature sperm cells travel to the man’s internal reproductive system where they are mixed with semen and ejaculated through the penis.
semen
white/yellowish fluid composed of water, salt and fructose sugars designed to nourish and sustain sperm cells from their journey from the vagina
seminal vesicles
small glands located in the upper internal end of each vas deferens
ejaculatory duct
directs semen into the urethra
prostate gland
adds prostatic fluid to semen
prostatitis
bacterial infection of the prostate gland
urethral bulb
portion of the urethra surrounded by the prostate gland.
Cowper’s glands
one on each side of the urethra, adds a small amount of fluid to the semen. secretes fluid into the urethra and out through the penis before ejeaculation
pre-ejaculate
during sexual arousal a small amount of clear, thick, slippery fluid from the Cowper’s glands may appear at the urethral opening at the tip of the penis.
