ANS

A

Controls organs and glands

22
Q

Parasympathetic

A

calming, digesting, relaxing

23
Q

Sympathetic

A

arousing fight or flight

24
Q

Autonomic

A

maintains homestasis, involuntary movements

25
Q

Frontal Lobe

A

Planning, Problem solving, motivation , judgment, decision making, impulse control,
social behavior, personality , memory , learning, award , attention

26
Q

Parietal Lobe

A

awareness of somatic sensation : touch, pain, temperature, pressure, vibration
processing somatic sensation: Analyzing/Recognizing memory of somatic sensation spacial and body awareness

27
Q

Occipital Lobe

A

Select, organize, integrate visual information

28
Q

Temporal Lobe

A

Awareness processing auditory Stimuli:
sounds of auditory stimuli: hearing pitch and frequency

29
Q

Brainstem

A

Analyzing Recognizing memory of auditory Stimuli ,
controls the flow of messages between the brain and the rest of the body (midbrain: earning
controls involuntary eye movement. Pons: cortex - cerebellum, facial sensitivity, REM Sleep. Medulla Oblon

30
Q

Cerebellum

A

coordinates movements, posture, balance, motor learning

31
Q

Thalamus

A

information processor for all senses

32
Q

Hypothalamus

A

maintain homeostaisis

33
Q

Hippocampus

A

Learning, memory encoding, spatial navigation

34
Q

Amygdala

A

Processing center for emotions

35
Q

Somatosensory pathway

A

first order neuron: sensory cell to spinal cord and midbrain
second order neuron: midbrain to thalamus
third order neruon: thalamus to respective sensory cortex

36
Q

Role of Na+

A

depolarization phase (membrane potential becomes +)

37
Q

Role of K+

A

Repolarization phase (membrane potential goes to resting state)

38
Q

Role of Ca2+

A

Nt release at axon terminal

39
Q

Role of Cl-

A

Influences resting membrane potential and inhibit excitation

40
Q

EPSP

A

makes membrane + =more likely AP will occur

41
Q

IPSP

A

makes membrane - = less likely AP will occur

42
Q

Glutamate

A

opens Na+ channels = excitatory

43
Q

GABA

A

open Cl- channels = inhibition

44
Q

Ionotropic`

A

open a channel

45
Q

metabotropic

A

intracellular response, swings both ways to open ion channels

46
Q

GPCR and taste

A

different GPCR for sweet sour bitter etc

47
Q

Olfactory Targets

A

nasal cavity cilia receptors then ORN which lead to olfactory bulb (base of brain) then target the amygdala and olfactory tubercle which go to orbitofrontal cortex, thalamus, and hypothalamus

48
Q

On center bipolar cells

A

hypoerpolarized(inhibit) in dark; rods and cones are depolarized
Depolarized(Exciteted) in light rods and cones are hyperpolarized

49
Q

off center bipolar cells

A

depolarized in dark, rods cones depolarized

hyperpolarized (inhibited) in light rods cones are hyperpolarized

50
Q

targets of optic nerve

A

Visual cortex (basics of what we see)
Pretectum: light reflex
Superior colliculus: visual and motor maps
suprachaismattic nucleus: light stimulates gluta neurons (light/dark cycle)
