PHYSIOLOGY 1021 REPRODUCTIVE SYSTEM
Mitosis vs. Meiosis - (ANSWER)Mitosis: one division forming 2 identical cells (clones)
(identical - 46 chromosomes - diploid)
Meiosis: two divisions forming 4 genetically different cells
(unique- 23 chromosomes- haploid)
function of male reproductive system - (ANSWER)The function of the male reproductive
system is to reproduce- to provide half of the genetic material, in the form of spermatozoa
necessary to make a new person, and then successfully storing, transporting, and
delivering this material to female counterpart, the ovum (or egg).
evidence that the reproductive system does not function primarily to maintain
homeostasis? - (ANSWER)- varies over a lifetime
adult: reproduction
- produce gametes (spermatozoa/oocytes)
- produce sex steroids (androgens, progesterone, estrogen)
- female: pregnancy and delivery
what is the site of hormone and sperm production is the ________ - (ANSWER)testis
testis - (ANSWER)male gonad
seminiferous tubules - (ANSWER)Narrow, coiled tubules that produce sperm in the testes.
Epididymis - (ANSWER)A long, coiled duct on the outside of the testis in which sperm
mature.
- stores the sperm and maturation
- approx 70 day until sperm reaches testies
, PHYSIOLOGY 1021 REPRODUCTIVE SYSTEM
vas deferens - (ANSWER)- Long, narrow tube carrying sperm from epididymis to
ejaculatory duct
- for sperm and fluid release (storage cite for sperm too)
muscles of the scrotum - (ANSWER)cremaster muscle and dartos muscle
- in scrotum can raise and Lower the temperature of vesicles by moving them closer or
farther to the body
Components of seminiferous tubules - (ANSWER)- spermatocytes
- sertoli cells
- leydig cells
- spermatids
- spermatogonia
- spermatozoa
spermatocyte - (ANSWER)- a cell produced at the second stage in the formation of
spermatozoa, formed from a spermatogonium and dividing by meiosis into spermatids.
- developing sperm cells
Sertoli cells - (ANSWER)cells found within the seminiferous tubules that provide metabolic
support for the spermatids
- support and regulate, and create sperm
Leydig cells - (ANSWER)produce testosterone
