	a.	Proprioceptors
	b.	Osmoreceptors
	c.	Baroreceptors
	d.	Nociceptors
	e.	none of the above

Answer 1

The correct answer is (d)nociceptors.
Pain receptors are also known as nociceptors . These are neurons with specialised nerve endings. These type of receptors can sense noxious stimuli and send signals to the brain and spinal cord. They are widely distributed in the skin and also in the deep tissues and organs.

Proprioceptors respond to movement and position.

Osmoreceptors detect changes in the osmotic pressure.

Baroreceptors are mechanical receptors. They respond to pressure changes in the arterial wall.
