|
Gametes
|
for males it is sperm and for females it is eggs. These are haploid and create a diploid zygote in a process called fertilization
|
|
|
zygote
|
fertilized egg
|
|
|
testosterone
|
male sex hormone/principal androgen
|
|
|
estrogen
|
female sex hormone
|
|
|
Sertoli cells
|
provides nutrients for the developing sperm
|
|
|
Parthenogenesis
|
form of asexual reproduction in which an unfertilized egg develops into a human, bees for example
|
|
|
ovum
|
egg
|
|
|
seminiferous tubules
|
where spermatogenesis takes place, these tubes are located in the testes
|
|
|
acrosome
|
covers the nucleus of the sperm, it was differentiated from the golgi complex
|
|
|
epididymis
|
where sperm are stored
|
|
|
urethra
|
In males, the urethra lets urine or semen pass out of the body through the penis; in females it only excretes urine
|
|
|
prepuce
|
foreskin
|
|
|
interstitial cells
|
produces testosterone
|
|
|
FSH ( follicle stimulating hormone)
|
In both males and females, FSH is secreted when GnRH stimulates the anterior pituitary. But in males FSH stimulates the Sertoli cells to secrete ABP,which stimulates spermatogenesis, whereas in females FSH stimulates the the development of follicles and secretion of estrogen.
|
|
|
ovaries
|
female gonads; produce gametes and hormones
|
|
|
oogenesis
|
production of ovum, this begins in the ovaries
|
|
|
primary oocyte
|
increased in size oogonia. By the time of birth they are in prophase 1
|
|
|
follicle
|
the primary oocyte and the granulosa cells
|
|
|
granulosa cells
|
forms a protective barrier around the primary oocyte
|
|
|
oviduct
|
fallopian tubes, where the ovum first goes when ovulation occurs, this is the site of fertilization
|
|
|
endometrium
|
sheds from the uterine wall, this is exposed from the body in the form of blood, which is the period
|
|
|
corpus luteum
|
temporary endocrine gland that secretes estrogen and progesterone
|
|
|
secondary oocyte
|
forms as the follicle matures and is the result of the first meiotic division. this later goes through meiosis to produce the ovum
|
|
|
zona pellucida
|
layer of glycoproteins that surrounds the follicle
|
|
|
oxytocin
|
released from the posterior pituitary, this hormone stimulates the ejection of milk
|
