Final Lab Exam: Male Reproductive System Flashcards
1
Q
Scrotum
A
- the bag of skin that holds and helps to protect the testicles
2
Q
Testis
A
- 2 small organs that are found inside the scrotum
- responsible for making sperm
- involved in producing a hormone called testosterone
3
Q
Epididymis
A
- site of sperm maturation and storage
4
Q
Ductus deferens
A
- tube between epididymis and seminal vesicle
- ascends spermatic cord, enters pelvic cavity, travels to urinary bladder and enlarges to a terminal ampulla; ends when it unites with duct of seminal vesicle
- thich wall of smooth muscle innervated by sympathetic nerve fibers
5
Q
Urinary bladder
A
hollow muscular organ that acts as a reservoir for urine
6
Q
Seminal vesicle
A
- pair of glands posterior to bladdder
- empty into ejaculatory duct
- forms 60% of semen
7
Q
Prostate
A
- surrounds urethra and ejaculatory duct just inferior to the bladder
- 30 to 50 compound tubuloacinar glands, empty through about 20 pores in the prostatic urethra
- thin, milky secretion forms 30% of semen
8
Q
Bulbourethral gland
A
- near bulb of penis
- produce a clear slippery fluid (pre-ejaculate) that lubricates the head of the penis in preparation for intercourse
- protects sperm by neutralizing acidity of residual urine in urethra
9
Q
Urethra
A
- tube that lets urine leave your bladder and your body
10
Q
Corpus cavernosum
A
- diverge like arms of a Y; each arm, called a crus, attaches penic to pubic arch
- covered with ischiocavernosus muscle
11
Q
Corpus spongiosum
A
- single
- along side of ventral side of penis
- encloses spongy (penile) urethra; distal end enlarges and forms the glans penic
- proximal end is a dilated bulb ensheathed by bulbospongiosus muscle
12
Q
Glans of penis
A
- genital tubercle becomes the head of the penis
- single corpus spongiosum enlarges and forms the glans penis
