Q

how does the cerebrum have a large surface area and what does this do

A

it’s highly convoluted and it’s surface area increases its capacity for complex activity

Q

what does each lobe in the hemispheres do and what do they have a function in smell sight

A

it receives information from receptor cells in each sense organ so has a function in smell sight speech and hearing

Q

how do the lobes send electrical impulses from the information they receive

A

they receive information from receptor cells in sense organs the information is then passed on to other parts of the brain called ‘association areas’ which coordinate a response and send electrical impulses to effectors via motor neurones

Q

what can damage to the medulla oblongata cause

A

paralysis from the neck down

17
Q

what does the medulla oblongata contain

A

many regulatory centres for the autonomic nervous system

18
Q

what is the hypothalamus a controlling region for

A

the autonomic nervous system

19
Q

what two centres does the hypothalamus have

A

sympathetic and parasympathetic

20
Q

what are the functions of the hypothalamus

A

it controls feeding/sleeping patterns it monitors body water potential and glucose concentration and produces hormones involved in urine production eg ADH

21
Q

what does the cerebellum control and what happens if this part of the brain gets damaged

A

it controls involuntary muscular movements/coordination, posture and balance it doesn’t initiate movement but coordinates
if this part of the brain gets damaged the person will have uncoordinated jerky movements it can also cause paralysis from the neck down

22
Q

how did the cerebellum relay the information it receives

A

it receives information from balance organs in the ears and from muscles and it relays this information to the part of the cerebrum that’s involved in motor control
