epididymis, vas deferens, ejaculatory duct, urethra, scrotum and penis
What are the 6 male secondary sex organs?
epididymis
comma-shaped organ on the posterior side of testes
head, body and tail
3 regions of epididymis
ductus epididymis
the epididymis contains a coiled tube called
store sperm for several months, maturation site of sperm and site where flagellum becomes more functional, secrete glucose to feed the sperm, site of old sperm to be phagocytized and absorbed and site where sperm leaves the epididymis and enter the vas deferens
what are the 5 functions of the epididymis?
Ductus Deferens
Another name for Vas deferens
vas deferens
18 inch long muscular tube within the spermatic cord that transports sperm by peristalsis
transport sperm
purpose of vas deferense
seminal vesicle duct
both of the vas deferens will unite with a _______________ and lead into the ejaculatory duct
alkaline
Semen (acidic/alkaline)
acidic
pee (acidic/alkaline)
urethra
8 inch tube divided into 3 regions that transports urine and semen
urine and semen
what does urethra transport?
prostatic, membranous and spongy urethra
what are the 3 regions of urethra
scrotum
large pouch of skin and subcutaneous tissue located on the ventral base of the penis, anterior to the anus
smooth muscle
what type of muscle is dartos?
scrotal septum
the scrotum is divided into 2 compartments by a partition of dense c. t. called
support and protect the testes, help regulate body heat for sperm development, dartos and cremaster muscle to contract under involuntary sympathetic innervation (stimualted by col temp, or sexual excitement
3 functions of scrotum
penis
cylinder shaped organ of copulation
transport urine and semen to the outside
what is the function of penis
body or shaft and glans penis
what are the 2 regions of the penis
penis
elongated regions composed of 3 columns of erectile tissue
corpora cavernosa
what is the dorsal column of the shaft of penis
tunica albuginea
corpora cavernosa is surrounded by
corpus spongiosum
the single ventral column is called
surrounds the spongy urethra and is surrounded by tunica albuginea
what does the corpus spongiosium surrounds and is surrounded by
glans penis
acorn-shaped distal end of corpus spongiosum
corona of glans
what is the proximal margin or ridge of the glans penis
prepuce
what is the loose fold of skin that covers the glans penis
frenulum of glans
the prepuce is attached to the glans on the ventral side called
circumcision
what do you call the surgical removal of prepuce
smegma
shed skin cell, oil secretions and anything that occurs between the glans and prepuce
seminal vesicles, prostate gland and cowper's gland
What are the 3 accessory glands for semen
posterior base of bladder combined with vas deferens to form the ejaculatory duct
seminal vesicles are located at
exocrine
seminal vesicle (endocrine or exocrine)
exocrine
prostate gland (endocrine or exocrine)
exocrine
cowpers gland (endocrine or exocrine)
inferior to the urinary bladder surrounding the prostatic urethra
where is the prostate gland located
below the prostate on each side of the membranous urethra
where is the cowpers gland located
semen
sperm and accessory gland fluids
testis, seminal vesicles, prostate and cowpers gland
what are the 4 sources of semen
water, sperm, mucus, fructose, seminal plasmin and prosta glandins
what is the composition of semen?
raise pH to neutralize the male urethra and acidic vagina
what the purpose of the mucus from semen
acts as an antibiotic
what the purpose of the seminal plasmin in semen
to give energy source for sperm
why is there fructose in semen
seminal vesicles
fructose are the energy source for sperms, this is secreted by the
acts as hormones to cause reverse peristalsis of uterus
purpose of prosta glandins in semen
2-5 ml, 300 mil sperm
what is the volume of semen and amount of sperm
7.2 to 7.8
what is the pH of semen
