Answer 1

cerebrum

cerebellum

hypothalamus, pituitary gland

medulla oblongata

Question 2

what is the function of the cerebrum

Answer 2

carry out higher thought processes
problem solving
memory
thinking
emotional response
intelligence
judgement

Question 3

the cerebrum is divided into two …?

Answer 3

two cerebral hemispheres

Question 4

what is important about the two cerebral hemispheres of the brain

Answer 4

the right hemisphere controls the left side of the body.
vice versa

Question 5

what is the name for the outer layer of the cerebrum

Answer 5

cerebral cortex

Question 6

what does the cerebral cortex consist of

Answer 6

neurone cell bodies

Question 7

what is the other name for the cerebral cortex

Answer 7

grey matter

Question 8

why is it advantageous for the cerebral cortex to be consisted of neurone cell bodies

Answer 8

more neurones- more connection between neurones- greater ability to carry out complex behaviour

Question 9

what connects the two cerebral hemispheres

Answer 9

corpus callosum

Question 10

the grey matter on the outer side of the cerebrum is cerebral cortex neurone cell bodies

what is the white matter inside the cerebrum

Answer 10

myelinated axons of neurones

Question 11

the cerebrum also contains 3 areas

Answer 11

sensory area
association area
motor area

Question 12

what does the sensory area

Answer 12

recieves action potential from sensory receptors

Question 13

what do association areas do in the cerebrum

Answer 13

compare sensory inputs with previous experience and judge a response

Question 14

what do motor areas do in the cerebrum

Answer 14

send action potentials to effectors

Question 15

if the motor area of the cerebrum is on the left of the brain what side will the effectors be on which it controls

Answer 15

if the motor area is on the left side it will control effectors on the right side of the brain

Question 16

what are effectors

Answer 16

muscles or glands

Question 17

how are the cerebrum and cerebellum connected

Answer 17

the pons

Question 18

what part of the brain contains the majority of neurones

Answer 18

cerebellum

Question 19

what is the function of the cerebellum

Answer 19

balance and fine coordination

Question 20

what are some sensory receptors which can supply input to the cerebellum

Answer 20

retina
balance organs in the ear
spindle fibres in the muscle

Question 21

where is the decision to contract voluntary muscle initiated

Answer 21

cerebral cortex

Question 22

what area of the brain coordinates fine control and balance

Answer 22

cerebellum

Question 23

what are some actions that are controlled by cerebellum

Answer 23

body position when riding a bike
tensing muscles when playing an instrument
coordinating contraction of antagonistic muscles when running

Question 24

when do actions produced by the cerebellum become second nature or unconscious controlled

Answer 24

when they have been learned
nervous pathways are strengthened through the process of learning or practice

Question 25

where is the cerebellum located in the brain

Answer 25

lies below the cerebrum
