ch 7 structure/function

Question 1

two main parts of the forebrain

Answer 1

diencephelon

telencephalon

Question 2

diancephalon

Answer 2

contains thalamus and hypothalamus which are

responsible for such functions as motor control, relaying sensory information, and controlling autonomic functions.

Question 3

telencephalon

Answer 3

contains cerebrum

consists of two cerebral hemispheres

deals with high level thinking

Question 4

diencephelon

Answer 4

relays sensory information between brain regions and controls many autonomic functions of the peripheral nervous system.

works with the limbic system structures to generate and manage emotions and memories

includes the thalamus and hypothalamus.

Question 5

thalamus

Answer 5

all sensory input goes through thalmus

it acts like a gateway to the cerebrum

Question 6

hypothalmus

Answer 6

deals with homeostasis, emotion, biological needs, autonomic nervous system

sends signals to pituitary gland (what hormones to secrete)

Question 7

midbrains tectum

Answer 7

responsible for auditory and visual reflexes

has superior and inferior colliculus

superior-recieves input from retina and visual cortex. participates in visual reflexes

inferior colliculus-part of auditory pathway

Question 8

two dopamine pathways

Answer 8

nigrostriatial-motor behavior

mesolimbic pathway-reward and pleasure

Question 9

substantia nigra

Answer 9

critical role in modulating motor movement and reward function

Question 10

venteral tegmentum

Answer 10

sends dopaminergic neural projections to both the limbic and cortical areas

Question 11

tegmentum

Answer 11

controlling basic body and limb movements

Question 12

two major structures within the midbrain tegmentum

Answer 12

substantia nigra and the ventral tegemental area

Question 13

where is NE produced

Answer 13

locus coeruleus

part of hindbrain

Question 14

what is the HPA regulated by

Answer 14

amygdela and hippocampus

Question 15

basal ganglia

Answer 15

control of voluntary motor movements, procedural learning, habit learning, eye movements, cognition, and emotion.

Question 16

main function of thalmus

Answer 16

relay motor and sensory signals to the cerebral cortex

Question 17

limbic system

Answer 17

allows for shortcuts for

intuitive responses

Question 18

Kahneman’s System 1

Answer 18

instinctual and emotional

Question 19

Kahneman’s system 2

Answer 19

reason, logic and abstract thinking

Question 20

how thick is human cortex

Answer 20

1?4th inch

has 6 layers

Question 21

basal telencephalon

Answer 21

composed of neurons that synthesize acetylcholine and/or GABA

Question 22

vagus nerve (10)

Answer 22

parasymathetic control of heart, lungs and abdominal organs (visceral motor)

sensation of pain located in viscera (visceral sensory)

movement of muscles in throat (somatic motor)

Question 23

olfactory nerve (1)

Answer 23

sensation of smell

Question 24

auditory vestibular nerve (8)

Answer 24

sensation of hearing and balance

Question 25

optic nerve (2)

Answer 25

sensation of vision

Question 26

different types of axons for cranial nerves

Answer 26

special sensory

visceral motor

somatic motor

somatic sensory

visceral sensory

Question 27

the vagus nerve has what kinds of axons

Answer 27

visceral motor

visceral sensory

somatic motor

Question 28

moro reflex

Answer 28

when babies throw their hands up and arch their back then they are falling or being set down in a fast manner

Question 29

Pons

Answer 29

Relay sensory information between cerebrum and cerebellum

Question 30

Medulla

Answer 30

Control of involuntary functions such as helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing
