Answer 22

Subarachnoid space

Question 23

Role of the midbrain

Answer 23

Contains tracts that relay sensory and motor impulses, contains centres for auditory and visual reflexes, contains clusters of neurons integral to muscle control

Question 24

Role of the pons

Answer 24

Contains tracts that convey signals to and from different parts of the brain

Question 25

Main centres of medulla oblongata

Answer 25

Cardiac centre, Vasomotor centre, two respiratory centres

Question 26

Thalamus role

Answer 26

Processes sensory inputs and decides which ones to transmit to the cerebral cortex, involved in memory and emotion

Question 27

Hypothalamus role

Answer 27

Controls autonomic nervous system, contains centres for hunger, thirst and temperature regulation, controls pituitary gland
