Answer 2

associated with: - higher processing and intelligence - regulation of motor function - smell and memory and emotions

Question 3

What is the function of the basal nuclei?

Answer 3

• controls voluntary movement and functions involved in motor planning centres

Question 4

What is the function of the thalamus?

Answer 4

• principle relay centre for sensory information that is projecting to the cortex

Question 5

What is the function of the tectum?

Answer 5

• two pairs of swellings that act as relay systems for visual and auditory inputs

Question 6

** What is the structures comprise the limbic system and what is their function?

Answer 6

• structures that comprise the limbic system consist of cortical gyri, the hippocampus, the fornix and the amygdala The functions of the limbic system are: - Emotions- fear - Spatial and short term memory - The amygdala is active in aggressive behaviour and fear

Question 7

What is the main function of the epithalamus (pineal)?

Answer 7

The main function of the pineal gland is to secrete melatonin

Name the structure circled and state it’s function:

Answer 9

Epithalamus (pineal gland) - the main function of it is that it secretes melatonin

Question 19

What is the function of the lateral and medial geniculate processes?

Answer 19

Often difficult to see but they are relay points for vision and auditory circuits

Question 20

What is the function of the amygdala?

Answer 20

Active in agressive behaviour/fear

Question 21

What is the function of the reticular formation?

Answer 21

Chains of nuclei forming a network that ends in the thalamus. The thalamus can be though of as the head of the process.
