Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which part of the brain serves as a relay station for information entering the brain?
A
Thalamus
B
Hypothalamus
C
Hypocretins
D
Orexins
Explanation: 

Detailed explanation-1: -Your thalamus serves as the main relay station for your brain. All motor and sensory signals (except smell) pass through this structure in the center of your brain. Your thalamus is arranged in regions, called nuclei, that each possesses specialization for dealing with that particular information.

Detailed explanation-2: -The thalamus relays sensory impulses from receptors in various parts of the body to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation. This sensation is then passed onto the cerebral cortex for interpretation as touch, pain or temperature.

Detailed explanation-3: -The thalamus is a paired gray matter structure of the diencephalon located near the center of the brain. It is above the midbrain or mesencephalon, allowing for nerve fiber connections to the cerebral cortex in all directions-each thalamus connects to the other via the interthalamic adhesion.
