Functions of parts of the brain

Question 1

What is the function of the cerebellum and what part of the brain is it located in?

Answer 1

Cerebellum is best known for its function in coordination, control and timing of complex movements, also plays a role in cognitive functioning

Part of the Hindbrain

Question 2

The function of the Cerebrum?

Answer 2

• Cerebrum - plays a key role in initiating and coordinating movement links with cerebellum

Question 3

What is the function of the Diencephalon?

Answer 3

• It integrates sensory and motor information on it’s way to the cerebral cortex, within the diencephalon the key features are the hypothalamus and the thalamus

Question 4

What is the function of the;
- SNS
- ANS
- ENS

Answer 4

SNS - Includes all the spinal and cranial nerves and carries info to the CNS from the muscles, joints and the skin. Also transmits outgoing motor instructions that produce movement

ANS - Produces rest-and-digest response through the sympathetic and parasympathetic branch

ENS - formed by a mesh of neurons in the lining of the gut and it controls the gut. Mostly operates autonomously

Question 5

What are the 5 anatomical categories of the spinal nerves ?

Answer 5

• Cervical
• Thoracic
• Lumbar
• Sacral
• Coccygeal

Question 6

What is the ‘Law of Bell and Magendie’ ?

Answer 6

Law of Bell and Magendie - Sensory fibres are dorsal and motor fibres are ventral

dorsal - facing upwards (above)
Ventral - facing downwards (below)

Question 7

What is the difference between gray matter and white matter ?

Answer 7

Gray matter - Areas of the nervous system composed of neuronal cell bodies and that collect and modify information and capillary blood vessels that support this activity

White matter - Areas with fat-rich, myelin sheathed neuronal axons that form connections between neurons
