What does third ventricle refer to?

  1. Cavity of diencephalon

  2. Cavity of medulla oblongata

  3. Cavity of mesencephalon

  4. Nerve fibre joining the hemispheres of cerebrum


Correct Option: A
Explanation:

Cavity of diencephalon is known as third ventricle.

Which area serves as the relay centre for sensory and motor impulses from spinal cord and brain stem to various parts of the cerebrum?

  1. Hypothalamus

  2. Thalamus

  3. Neurohypophysis

  4. Hippocampus


Correct Option: B
Explanation:

Thalamus is the area which serves as the relay centre for sensory and motor impulses from spinal cord and brain stem to various parts of the cerebrum.

Which part of the brain is the link between the endocrine system and the nervous system?

  1. Thalamus

  2. Hypothalamus

  3. Cerebellum

  4. Medulla


Correct Option: B
Explanation:

Hypothalamus links the nervous system to the endocrine system and controls the functioning of the endocrine glands.

Which part of the brain coordinates the muscle movements on the two sides of the body?

  1. Cerebellum

  2. Pons

  3. Medulla

  4. Corpora quadrigemina


Correct Option: B
Explanation:

Pons varolli coordinates the muscle movements on the two sides of the body.

Which canal connects the third ventricle to the fourth ventricle?

  1. Diocoel

  2. Metacoel

  3. Iter

  4. Neopallium


Correct Option: C
Explanation:

Iter is a narrow canal which connects the fourth ventricle to the third ventricle.

What is the middle zone of cerebellum called?

  1. Neocortex

  2. Folium

  3. Vermis

  4. Granule cell


Correct Option: C
Explanation:

The central lobe or middle zone of cerebellum is called vermis.

Which part of CNS causes disorder in equilibrium on being damaged?

  1. Cerebrum

  2. Cerebellum

  3. Medulla oblongata

  4. Spinal cord


Correct Option: B
Explanation:

Cerebellum controls coordination and balance. Damage to cerebellum causes disorder in equilibrium.

Which area connects the anterior thalamus to the posterior hypothalamic region?

  1. Mammillotegmental tract

  2. Mammillothalamic tract

  3. Lateral spinothalamic tract

  4. Ventral spinothalamic tract


Correct Option: B
Explanation:

The term mammillothalamic tract refers to a fibre pathway that originates from neurons in the posterior hypothalamic region and projects to various nuclei of the anterior nuclear group of the thalamus.

In most people where is the language area situated in the brain?

  1. Right hemisphere

  2. Left hemisphere

  3. Center of brain

  4. Medulla


Correct Option: B
Explanation:

In most people, the language area is chiefly on the left.

Which are the largest neurons in the human brain?

  1. Granule cells

  2. Purkinje cells

  3. Lugaro cells

  4. Pleiomorphic cells


Correct Option: B
Explanation:

Purkinje cells are the largest neurons in the human brain.

What are immune cells of the brain called?

  1. Hofbauer cell

  2. Intraglomerular messangial cells

  3. Microglial cells

  4. Red pulp macrophage


Correct Option: C
Explanation:

They are the immune cells of CNS which includes brain.

Which centre of Medulla oblongata regulates heart beat?

  1. Reflex centres

  2. Vital cardiac centre

  3. Medulla

  4. Promotor area


Correct Option: B
Explanation:

Cardiac centre of vital centres regulates heart beat.

Where are the Purkinje cells located?

  1. Cerebrum

  2. Cerebellum

  3. Medulla oblongata

  4. Heart


Correct Option: B
Explanation:

Purkinje cells are found in cortex of cerebellum of brain

What is the cavity of medulla called?

  1. Diocoel

  2. Iter

  3. Metacoel

  4. Paracoel


Correct Option: C
Explanation:

Metacoel is the inner cavity of medulla.

Which glial cells are involved in synthesis of myelin?

  1. Astroglia

  2. Oligodendroglia

  3. Microglia

  4. Purkinje cells


Correct Option: B
Explanation:

Oligodendrocytes (Oligodendroglia) form myelin in the CNS and hence are responsible for normal propagation of action potentials.
