Question

What Receptor in the human body detects Pressure, gravity and sound ?

Answer 1

I suspect you want the cochlea ( inner ear )

Answer 2

The listed types of sensitivity are all handled by mechanoreceptors, that respond to mechanic stimuli, such as pressure from objects, pull from gravity or the vibrations in the air that are sound.

Answer 3

All the jobs mentioned are carried out by the vestibular labyrinthine system found in both the inner ears.

The cochlea, dedicated to hearing......
The vestibular system, dedicated to balance.......
