increase arterial stiffness

19
Q

artery in I and aVL

A

left circumflex

20
Q

sympathetic effects of dopamine

A
  • low dose = increase in renal blood flow
  • medium dose = beta 1 agonist
  • high dose = alpha 1 agonist
21
Q

protective factors for ovarian cancer

A
  • having kids
  • breast feeding
  • oral contraceptives
22
Q

cells that get GLUT4 receptors

A

adipose and muscle

23
Q

nerves of the leg

A
  • iliohypogastric = motor to anterolateral abdominal wall, skin above pubic region and gluteal region
  • genitofemoral = sensation to upper anterior thigh and motor to cremaster
  • ilioinguinal = sensation to genitals and upper medial thigh
24
Q

pancreatic pseudocyst is lined by…

A

fibrous and granulation tissue (not cells)

25
gaps in BBB
- area postrema (vomiting after chemo) | - organum vasculosum lamina terminalis (osmotic sensing)
26
lateral hypothalamus
- controls hunger | - destruction = anorexia and failure to thrive (if you zap laterally, you shrink laterally)
27
ventromedial hypothalamus
- controls satiety | - destruction = hyperphagia (if you zap ventromedial, you grow ventrally and medially)
28
anterior hypothalamus
cooling, parasympathetic
29
posterior hypothalamus
warming, sympathetic
30
suprachiasmatic hypothalamus
circadian rhythm
31
supraoptic and supraventricular hypothalamus
oxytocin and ADH
32
treatment for bed wetting
ADH
33
treatment of night terrors
benzos (and sleep walking)
34
ventral posterolateral thalamus
vibratory, pain, pressure, proprioception, light touch and temperature - spinothalamic and dorsal columns, medial lemniscus
35
ventral posteromedial thalamus
face sensation and taste (makeup goes on the face)
36
lateral geniculate thlamus
vision (lateral = light)
37
medial geniculate nucleus
hearing from superior olive and inferior colliculus to auditory cortex (medial = music)
38
ventral lateral thalamus
motor to motor cortex
39
mesocortical dopamine pathway
less activity gives negative symptoms
40
mesolimbic dopamine pathway
more activity give positive symptoms
41
jaw muscles
lateral lowers and medial munch
42
moro reflex
hang on for dear life, extend arms and draw together
43
frontal eye field lesion
looks toward lesion
44
