Q

what hormone does the thymus produce

A

thymosin

25
Q

what hormone does the pineal gland produce

A

melatonin

26
Q

key feature of pineal gland

A

pineal sand

27
Q

steps in producing progesterone and estrogen

A

FSH stimulates follicle development
LH stimulates ovulation
follicles produce estrogen
after ovulation progesterone is produced

28
Q

features of the ovary

A

germinal epithelium, primary follicles (not mature yet so looks like just a circle), oogonia, graafian follicles (mature), oocytes (egg)

29
Q

features of testes

A

seminiferous tubules, interstitial cells-produce testosterone

30
Q

steps in testosterone production

A

FSH stimulates spermatogenesis

LH stimulates the production of testosterone

31
Q

releasing hormones from hypothalamus

A

CRH, GnRH, TRH, GHRH

32
Q

inhibiting hormones from hypothalamus

A

PIH and SST

33
Q

Cycle of CRH

A 
CRH
Anterior pituitary gland
ACTH
Adrenal gland 
epinephrine, norepinephrine, and cortisol
34
Q

cycle of GnRH

A 
GnRH
anterior pituitary gland
FSH/ LH
Testes and Ovaries 
testosterone/ estrogen and progesterone
35
Q

cycle of TRH

A 
TRH
anterior pituitary
TSH
Thyroid gland
T3, T4, calcitonin, thyroglobulin
36
Q

cycle of GHRH

A

GHRH
anterior pituitary
GH
liver, bone, muscles

37
Q

ADH stimulates what

A

goes through posterior pituitary
ADH
then to kidneys

38
Q

Oxytocin stimulates what

A

labor contractions and milk let down (posterior pituitary)

targets uterus and mammary glands

39
Q

p wave

A

1st wave

atrial depolarization resulting in atrial contraction

40
Q

QRS complex

A

onset of ventricular depolarization resulting in ventricular contraction

41
Q

T wave

A

ventricular repolarization

42

instrument for visual counting of the number of cells in a blood sample

44
Q

capillary tube

A

what the sample is put in to

45

centrifuge

A

machine that rapidly rotates to separate fluids of different densities

46
Q

agglutinate

A

clumping of blood when antigen match the antibodies like a lock and key

47
Q

universal donor

A

type O blood

48
Q

universal recipient

A

type AB blood

49
Q

antibodies

A

produced in response to contracting a specific antigen - floating around

50
Q

antigen

A

toxic substance that calls for an immune response - on the cell itself

51
