Q

reticular layer- receptors

A

lamellar corpuscles

20
Q

sudoriferous gland location: apocrine vs eccrine

A

apocrine- axillary and anogenital
eccrine- most common, everywhere else

21
Q

meissner’s corpuscle function

A

senses light touch and vibration

22
Q

merkel disc function

A

senses light and sustained pressure

23
Q

free nerve ending function

A

senses pain and temperature

24
Q

ruffini ending

A

sense deep pressure and skin stretch

25
Q

pacinian corpuscle

A

senses deep pressure and vibration

26
Q

pituitary gland is attached to the hypothalamus via

A

infundibulum

27
Q

hormones of the anterior pituitary gland (adenohypophysis)

A

FSH- follicle stimulating hormone
LH- luteinizing hormone
ACTH- adrenocorticotropic hormone
TSH- thyroid stimulating hormone
Prl- prolactin
GH- growth hormone

28
Q

hormones of the posterior pituitary gland

A

ADH, oxytocin

29
Q

thyroid gland hormones

A

T3, T4, calcitonin

30
Q

parathyroid gland

A

PTH

31
Q

adrenal cortex hormones

A

aldosterone, cortisol, androgens

32
Q

adrenal medulla hormones

A

epinephrine, norepinephrine

33
Q

testis hormones

A

primary source of androgens

34
Q

ovary hormones

A

primary source of estrogens

35
Q

endocrine pancreas hormones

A

insulin, glucagon

36
Q

why is a LP performed at L4 or L5?

A

because the conus medullaris is at L1/L2 so you are able to ensure you dont cause damage

37
Q

conus medullaris

A

end of the spinal cord

38
Q

cauda equina

A

not part of the spinal cord. its a collection of spinal nerves (think horse’s tail)

39
Q

dorsal vs ventral root

A

dorsal - sensory (afferent)
ventral- motor (efferent)

40
Q

dorsal ramus vs ventral ramus

A

dorsal- mixed motor and sensory
ventral- mixed motor and sensory

41
Q

what are the 4 nerve plexus?

A

cervical, brachial, lumbar, sacral

42
Q

cervical plexus

A

remember the phrenic nerve: C3,4,5- innervates the respiratory diaphragm

43
Q

brachial plexus

A

remember: axillary, musculocutaneous, radial, median, and ulnar nerves (terminal nerves are all of these except ulnar)

44
Q

do intercostal nerves form a plexus?

A

no. but they do innervate the trunk and arm

45
Q

lumbar plexus nerves to know

A

femoral and obturator nerves

46
Q

sacral plexus nerves to know

A

superior gluteal, inferior gluteal, sciatic, common fibular, tibial

47
Q

patellar reflex arc

A

receptor- quadriceps femoris
afferent neuron- femoral nerve
integration center- spinal cord
efferent neuron- femoral nerve
effector- quadriceps femoris
