Q

the ciliary muscles and processes function to do what?

A

help change the shape of the lens in order to focus

help filter plasma to create aqueous humor

28
Q

laminated corpuscles respond to

A

deep pressure

29
Q

tactile corpuscles respond to

A

touch and light pressure

30
Q

ruffini’s corpuscles responds to

A

deep pressure & stretch

31
Q

free nerve endings respond to

A

temperature & pain

32
Q

what was the point of the 2 point discrimination test?

A

to understand that density of touch receptors in the skin vary in different parts of the body

33
Q

where is the greatest touch receptor density in the body?

A

finger tips

34
Q

the vestibule functions in

A

balance & equillibrium

35
Q

the semicircular canals function in

A

balance and equillibrium

36
Q

the cochlea functions in?

A

hearing

37
Q

the spinal nerve is where

A

anterior and dorsal roots are fused becoming the nerve

38
Q

the grey commissure is what?

A

commisural tissue that connects the 2 sides of grey mater

at its center there is the central canal, where CSF is found

39
Q

function of the scleral venus sinus

A

collecting aqueous humor

returns it to the blood

40
Q

what do cow eyes have that human eyes do not? what is its function? where is it located?

A

tapetum lucidum
night vision
just beneath the retina

41
Q

anabolism describes

A

chemical reactions that build up molecules

42
Q

catabolism describes

A

chemical reactions that break down molecules

43
Q

catabolic reactions release…

A

energy
some used for cell functioning
some released as heat

44
Q

when catabolism is accelerated…

A

the body burns more calories & produces more heat

45
Q

when catabolism is slowed…

A

the body burns fewer calories and produces less heat

46
Q

islet cells are in what hormone releasing organ?

A

pancreas

47
Q

islet cells include what?

A

alpha and beta cells

48
Q

alpha cells secrete what?

A

glucagon

49
Q

beta cells secrete what?

A

insulin

50
Q

the colloid is on what hormone secreting gland?

A

thyroid

51
Q

what is the function of the colloid?

A

store iodine

52
Q

follicle cells are on what hormone secreting gland?

A

thyroid

53
Q

follicle cells function is…

A

release thyroglobulin into the colloid where it combines with iodine forming T3/T4

54
Q

parafollicular cells are on what hormone secreting gland?

A

thyroid

55
Q

parafollicular cells function is what?

A

releasing calcitonin

56
Q

hormone that directly maintains metabolism & thus body heat?

A

T4

57
Q

what two hormones indirectly influence metabolism by promoting or inhibiting T4? where are they from?

A

TRH - from hypothalamus

TSH - anterior pituitary

58
Q

blood plasma glucose is regulated by what 2 hormones? where are they secreted from and why?

A

insulin
glucagon
secreted by pancreas
part of neg. feedback loop that keeps blood glucose within a normal range

59
Q

insulin is released when

A

blood glucose rises (eating carbs)

60
Q

how does insulin low blood glucose to the normal range?

A

stimulating the uptake of glucose by the cells of the liver and muscles, the the cells glucose is made into glycogen for storage

61
Q

glucagon is released when

A

blood glucose falls below normal

62
Q

how does glucagon raise blood glucose back to its normal range?

A

by stimulating the liver to break down its glycogen into glucose and release it into the blood

63
Q

what is a disorder related to blood glucose regulation?

A

diabetes mellitus

64
Q

type 1 diabetes mellitus occurs when? what occurs? what is it?

A

beta cells of pancreas no longer produce / secrete insulin
blood glucose levels rise dangerously high
auto-immune disorder - immune system attacks pancreas’ beta cells

65
Q

type 2 diabetes mellitus occurs when? associated with what?

A

liver resists insulin, leaves excess glucose in the blood

associated with poor life style habits
