Male Reproductive System Flashcards
2 functions of the testes
- Spermatogenesis
2. Secretion of testosterone
3 functions of epididymis
- Duct for seminal fluid
- Secretes part of seminal fluid
- Sperm become capable of motility
2 functions of vas deferens
- Excretory duct for seminal fluid
2. Connects epididymis to ejaculatory duct
2 functions of urethra
- Reproductive duct
2. Urination
1 function of seminal vesicles
Secrete prostaglandins and viscous, nutrient-rich part of seminal fluid
1 function of prostate gland
Adds alkaline secretion to seminal fluid
1 function of bulbourethral glands
secrete alkaline fluid that is part of semen
5 secondary sex characteristics
- Body hair
- Facial hair
- Apocrine sweat glands
- Deeper voice (thyroid cartilage)
- Muscle development
5 influences of testosterone
- Spermatogenesis
- Development of reproductive structures
- Secondary sex characteristics
- Behavior
- Itself
Cells of Leydig/interstitial cells
produce testosterone in the presence of LH (luteinizing hormone)
Corpus cavernosum
sponge-like region of erectile tissue
Corpus spongiosum
a mass of erectile tissue
FSH
Follicle Stimulating Hormone; stimulates primary spermatocytes to undergo the first division of meiosis and helps with growth/development
LH/ICSH
Luteinizing hormone/Interstitial cell stimulating hormone; stimulates the production of testosterone
Inguinal canal
conveys the spermatic cord and the ilioinguinal nerve
Testosterone
hormone produced by the male reproductive system
Sertoli cells
a type of somatic cell around which spermatids develop in the tubules of the testis
Acrosome
cap-like structure over the anterior side of the head in spermatozoa
Seminiferous tubule
where meiosis takes place
Cremaster muscle
contracts to regulate scrotal temperature for optimal spermatogenesis
Prepuce
foreskin
Fossa navicularis
spongy part of the urethra
5 stages of spermatogenesis
- Spermatogonium
- Primary Spermatocyte
- Secondary spermatocyte
- Spermatid
- Sperm cell
