CNS - cerebellum + structures in the brainstem

Question 1

Medulla Oblongata

3

Answer 1

• Crucial part of the brain.
• Carries out critical functions such as breathing, swallowing and heart rate which are involuntary.
• Damage to this part causes quick death

Question 2

Pons

5

Answer 2

• Above medulla
• connects structures involved with the management of sleep, arousal and facial expressions.
• serves as the bridge between higher and lower parts of the brain
• connects the cerebellum to the rest of brain
• Very necessary – brain cannot function without pons because without it no messages would be transmitted

Question 3

Midbrain

2

Answer 3

• sits above the pons

- contains a number of structures involved in sensory reflexes, movement and pain

Question 4

Reticular formation

2

Answer 4

• Runs the length of the brainstem’s core from the upper medulla into the midbrain
• participates in the control of mood, arousal and sleep

Question 5

Cerebellum

2

Answer 5

• structure attached to the brainstem

- Essential for maintaining balance and motor coordination (voluntary tasks)
