Reproductive System Flashcards
FUNCTIONS OF REPRODUCTIVE SYSTEM
- Production of Gametes
- Fertilization
- Development and Nourishment of a new individual
- Reproduction of reproductive hormone
process where a single cell divides twice to produce four cells
containing half the original amount of genetic information.
Meiosis
MALE REPRODUCTIVE
SYSTEM consist of
Consist of testes, series of ducts (epididymis, vas deferens and urethra), accessory
glands (seminal vesicles, prostate gland, and bulbourethral gland), **supporting structures **
(scrotum and penis).
Sac like structures that contains the testes. Made up of skin, a layer of
loose connective tissue (divided into right and left by septum) and a
layer of smooth muscle called Dartos muscle.
SCROTUM
The scrotum is Made up of skin, a layer of
loose connective tissue (divided into right and left by _____) and a
layer of smooth muscle called ______.
septum;Dartos muscle
In cold temparatures the -__ contracts, causing the skin of the scrotum to become firm and wrinkled reducing its overall size.
Dartos muscle
are extensions of abdominal skeletal muscles into the scrotum, contract and help pull the testes nearer the body.
cremaster muscles
4-5 cm oval organs within each scrotum
TESTES (Male Gonads)
testes are responsible for making sperm (__) and are also involved in producing a hormone
called ___.
spermatozoa;testosterone
site of spermcell development
seminiferous tubules
interstitial cells secrete testosterone
leydig cells
Formation of sperm cells and
occur in the seminiferous tubules
SPERMATOGENESIS
the seminiferous tubules
which contains 2 type of cells
(1) germ cell
(2) **sustentacular cells or Sertoli **
are the ones that divide and ddifferentiate during spermatogenesis to form sperm cells
germ cells
they nourish the germ cells and produce a number of hormones
sustentacular cells or sertoli
4 ducts
1 epididymis
2. ductus deferens/vas deferens
3. seminal vesicle
4. ejaculatory duct
It is a coiled tube located in the
posterior side of the testis and is
divided into head, body and tail.
EPIDIDYMIS
The ___ of testis empties in the
*efferent ductules *to the epididymis.
rete
store sperm cell for maturation and
transport it to vas deferens.
EPIDIDYMIS
the physiological
changes spermatozoa must undergo
in order to have the ability to
penetrate and fertilize an egg.
CAPACITATION
tube that carries sperm from the testis into the body cavity of the male.
ductus deferens/ vas deferens
DEFERENS is 45 cm long and emerges from the ___ and becomes
associated wit the blood vessels
and nerves to form ___
epididymis;spermatic cord
spermatic cord (4)
ductus deferens, testicular artery
and vein, lymphatic vessels,
testicular nerve
DUCTUS DEFERENS / VAS
DEFERENS - Walls contains smooth muscle
which contracts in peristaltic waves
to propel sperm cells from
epididymis to ___ (widest
diameter)
ampulla
located between the bladder
fundus and the rectum. To
produce a fluid (alkaline) that
makes up majority of semen.
SEMINAL VESICLE
fluid that makes up majority of semen
alkaline
Enters through the prostate gland
transport spermatozoa and fluids
from the ampulla and seminal
vesicles to the prostatic urethra.
EJACULATORY DUCT
extends from the urinary bladder to the distal end of penis.
URETHRA
