1
Q
epididymides
A
- narrow, tightly coiled tubes at top of each testis
- promote maturation of sperm cells
2
Q
seminal vesicles
A
- secrete alkaline fluid, which regulates pH in male & female tracts
- secrete fructose & prostaglandins
- contents empty into ejaculatory duct
- contribute most to volume of semen
3
Q
ductus deferentia
A
- muscular tubes
- lined with pseudostratified columnar
4
Q
prostate
A
- composed of tubular glands in connective tissue
- contains smooth muscle
- secretes thin, milky, alkaline fluid
- secretion enhances sperm motility
- contributes to volume of semen
5
Q
PSA
A
prostate specific antigen
6
Q
BPH
A
benign prostatic hypertropy
7
Q
bulbourethral glands
A
- Cowpers glands
- lubricates end of penis
- fluid released in response to sexual stimulation
8
Q
semen
A
fluid conveyed to outside world through ejaculation
9
Q
semen composition
A
- sperm cells from testes
- slightly alkaline
- contains nutrients & prostaglandins
- volume is 2-5mL of semen per ejaculation
- avg. 120 million sperm cells per mL of semen
- sperm begin to swim as they mix w/ secretions of accessory glands
10
Q
scrotum
A
pouch of skin & subcutaneous tissue; located behind penis
11
Q
dartos muscle
A
smooth muscle in subcutaneous tissue
- contracts & relaxes in response to temp changes, to keep testes at optimal temp for sperm production & survival
- medial septum divides scrotum into 2 chambers
12
Q
penis
A
- body contains 3 column of erectile tissue
- 2 corpora cavernosa
- 1 corpus spongiousum
13
Q
glans penis
A
distal enlargement of corpus spongiousum
14
Q
prepuce
A
covering of glans penis
15
Q
emission
A
semen moved into urethra
