W4 - The Brain

Question 1

Cerebrum function

Answer 1

Contains sensory, motor and association areas from all 5 lobes (frontal, parietal, temporal, occipital & insula)

Question 2

Cerebellum function

Answer 2

Co-ordinates motor movements and maintains balance

Question 3

Thalamus function

Answer 3

Relay station - sorts and edits sensory information and conducts it to the relevant areas of the cerebral cortex. Also conducts impulses between the cerebral motor areas and the cerebellum

Question 4

Hypothalamus function

Answer 4

Controls and integrates activities of the ANS

Regulates emotions/behaviours, controls temp, hunger, thirst, sleep and produces hormones

Question 5

Epithalamus function

Answer 5

Secretes melatonin which is involved in sleep

Question 6

Midbrain function

Answer 6

Visual and auditory reflexes

Produces dopamine

Question 7

Pons function

Answer 7

Relays information between the cerebrum and the cerebellum
Various somatic and visceral motor centres
Controls breathing

Question 8

Medulla oblongata function

Answer 8

Conduction pathways between the brain and spinal cord
Autonomic centres for regulations of visceral functions (cardiovascular, respiratory, blood vessels, digestive system activities)
