Q

What happens when neurons are stimulated?

Q

When enough Na+ ions get in for the potential to be reduced to -55 mV, what happens?

A

The ion gates to the cell membrane are flung open, allowing Na+ to rush in

Q

How does the cell go back to resting potential?

A

by pushing out K+ ions (Na+ goes out slower), then another pump takes Na+ back out and puts K+ back in

Q

The peripheral nervous system is divided into…

A

the somatic nervous system and the autonomic nervous system

30
Q

What does the somatic nervous system control?

A

muscles and senses

31
Q

What does the autonomic nervous system control?

A

vital functions: heart rate, breathing, digestion, reproduction

32
Q

What are the two divisions of the autonomic nervous system?

A

sympathetic nervous system and parasympathetic nervous system

33
Q

Sympathetic nervous system

A

arousal: mobilizes for emergency

34
Q

parasympathetic nervous system

A

calm: conserves energy

35
Q

What are the parts of the hind brain?

A

medulla, pons, cerebellum

36
Q

what is the medulla responsible for?

A

breathing, heartbeat, blood circulation

37
Q

what are the pons responsible for?

A

arousal and attention

38
Q

what is the cerebellum responsible for?

A

integration of muscles to perform fine movements, but no coordination/direction of these movements; balance

39
Q

If a cat was transected just above the hindbrain how would it behave?

A

low-decerebrate cat; can move but not act

40
Q

What is the other name for the pons?

A

bridge

41
Q

Midbrain

A

forms movements into acts; controls whole body responses to visual and auditory stimuli

42
Q

How would a cat act if just transected just above midbrain?

A

can act, but without regard to environment, without purpose

43
Q

superior colliculus

A

part of the midbrain; “upper hills”

44
Q

substantia nigra

A

part of midbrain; “black substance”

45
Q

forebrain

A

cerebral hemispheres connected by corpus callosum

46
Q

what are the parts of the forebrain?

A

thalamus, hypothalamus, basal ganglia, limbic system, cerebral cortex

47
Q

thalamus

A

sensory and motor relay center

48
Q

hypothalamus

A

controls responses to basic needs (food, temp, sex)

49
Q

basal ganglia

A

regulates muscle contractions for smooth movements

50
Q

what are the parts of the limbic system

A

hippocampus and amygdala

51
Q

limbic system

A

memory (hippocampus) and emotion (amygdala)

52
Q

cerebral cortex

A

four lobes: frontal, parietal, occipital, temporal; seat of higher intellectual functions

53
Q

How would a cat behave transected above its limbic system?

A

acts normal, with purpose, but clumsy

54
Q

corpus callosum

A

connects hemispheres

55
Q

cerebral cortex

A

higher motor, sensory, and intellectual functions

56
Q

Broca’s aphasia

A

speech is diminished and there is a loss of normal grammatical structure

57
Q

Wernicke’s aphasia

A

speech comprehension is diminished

58
Q

frontal lobe

A

planning; social behavior; motor control

59
Q

parietal lobe

A

somatosensory (sense of touch) (on top and toward back of brain)

60
Q

occipital

A

vision

61
Q

71
Q

expressive aphasia

A

cannot produce speech; lesion to Broca’s area

72
