Term
| 2 main categories of hormones |
|
Definition
|
|
Term
|
Definition
*estrogen, testosterone, androgen
*secreted by cell that they act on, do not enter bldstrm
*doesn't like water (lipid-soluble) dissolves in fat, goes thru membrane |
|
|
Term
|
Definition
*ADH, insulin
1.binding of horm. to receptor activates g-protein
2.g-protein ->cytoplasm ->activates 2nd messenger
3.2nd messenger relays signal to nucleus |

Term
| Mechanism of Release for T3 and T4 |
|
Definition
| hypo -> TRH -> bldstrm -> ant. pit. -> TSH -> bldstrm -> thyroid -> releases t3 and t4 |
|
|
Term
|
Definition
1.development and maturation of vertebrates; reorg. of tissues, bone formation
2.regulate metabolism |
|
|
Term
| Pancreas and its 2 diff cells |
|
Definition
Islet cells:
a.alpha cells- detect low glucose in bld, produce glucagon
b.beta cells- detect hi glucose in bld, produce insulin |
|
|
Term
| Male Primate Anatomy 3 parts |
|
Definition
1.Testes: seminiferous tubules where sperm develops, release testosterone, housed in scrotum to maintain temp.
2.Epididymus: maturation & storage
3.Vas Deferens: tube thru which sperm travel during ejaculation |
|
|
Term
| 3 Glands in Semen Production |
|
Definition
1.semenal vesicle: produce most semen and fructose (give sperm e!)
2.prostate: alkaline fluid to balance acidity in vagina
3.bulbourethral glands: unknown function |
|
|
Term
| Hormonal control of reprod. in primate males |
|
Definition
| hypo -> GnRH -> ant. pit. -> release LH & FSH -> bldstrm -> testes -> release testosterone -> make sperm |
|
|
Term
|
Definition
1.head: nucleus w/dna, acrosome on tip-filled head contain enzymes which chew to penetrate egg
2.neck: mitochondria (give sperm ATP)
3.tail: flagellum |

Term
| 5 Reproductive Organs in Females |
|
Definition
1.ovaries: produce store eggs, release estrogen & progesterone
2.fallopian tube (oviduct): lined w/cilia which move eggs
3.uterus: smooth muscle
4.cervix: most narrow part of uterus
5.vagina: birth canal |
|
|
Term
| 3 phases in menstrual cycle |
|
Definition
1.Follicular Phase days 1-14
2.Ovulation day 15
3.Luteal Phase days 16-28 |
|
|
Term
|
Definition
1.primordial follicle, LH & FSH released, follicle starts to grow
2.granulosa cells divide, make estro & prgestro
3.zona pellucida sits between egg & gran cells
4.fluid filled cavity forms in gran cells=antrum
5.mature follicle -> antral follicle
6.LH surge released from ant. pit.
7.enzymes kick into action & chew thru peripheral cells, causes ovulation |
|
|
Term
|
Definition
*endometrium thick w/blood vessels
*surge of LH causes gran cells become corpus luteum, secretes e & p
*this surge shuts down production of LH & FSH |
