Question

Give any two functions of cerebellum.
Write the names of any four motor cranial nerves with their appropriate serial number.
Which hormones stimulate liver for glycogenesis and glycogenolysis?

Hint:

Cerebellum ensures smooth movements; insulin stores glucose, glucagon releases it.

Answer 1

i. Cerebellum Functions:
1. Coordinates voluntary movements and balance.
2. Regulates muscle tone and motor learning.
ii. Motor Cranial Nerves:
1. Oculomotor (III)
2. Trochlear (IV)
3. Abducens (VI)
4. Hypoglossal (XII)
iii. Hormones:
- Glycogenesis: Insulin (promotes glucose storage as glycogen).
- Glycogenolysis: Glucagon (promotes glycogen breakdown to glucose).
Answer: i. Movement coordination, muscle tone; ii. Oculomotor (III), Trochlear (IV), Abducens (VI), Hypoglossal (XII); iii. Insulin, Glucagon.
