Question

What are receptors with reference to nervous system?
List three types of receptors and mention their
functions. How do receptors pass the information to
brain?​

Answer 1

Answer:

• Receptors. Receptors are groups of specialised cells. They detect a change in the environment (stimulus) and stimulate electrical impulses in response. Sense organs contain groups of receptors that respond to specific stimuli.

:- Receptors are groups of specialised cells. ...

• 1)sensory neurons—receive impulses and carry them from the sense organs to the spinal cord or brain.
• 2) interneurons—connect sensory and motor neurons and interpret the impulse; only in the brain and spinal cord.

Answer 2

Answer:

1-Receptors. Receptors are groups of specialised cells. They detect a change in the environment (stimulus) and stimulate electrical impulses in response. Sense organs contain groups of receptors that respond to specific stimuli.

2-Chemoreceptors detect the presence of chemicals.

Thermoreceptors detect changes in temperature.

Mechanoreceptors detect mechanical forces.

Photoreceptors detect light during vision.

More specific examples of sensory receptors are baroreceptors, propioceptors, hygroreceptors, and osmoreceptors

3-To understand the world around us, our sensory receptors receive information in a process known as reception. They then transduce the information and code it according to qualitative and quantitative measures. Finally, it is transmitted to the brain, where it is interpreted.
