Dear Soumya,

Here is the explanation of your queries:
1. “pons acts as relay centre in different parts of brain”

Pons includes neural pathways or tracts that conduct signals from the brain down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus. The pons contains nuclei that relay signals from the forebrain to the cerebellum, along with nuclei that deal primarily with sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, facial sensation, and posture.

Coming to your next query
2. “pons Varolli pneumotactic area of brain”

Breathing is highly regulated and work in a controlled manner.
A neural center in the upper part of the pons (pneumotactic center) that provides inhibitory impulses on inspiration and thereby prevents over-distension(excessive stretching) of the lungs and helps to maintain alternately recurrent inspiration and expiration.


Hope the answer of the question!
