MEDICAL PHYSIOLOGY

Detailed explanation-1: -Through its receptors, the nervous system keeps us in touch with our environment, both external and internal. Like other systems in the body, the nervous system is composed of organs, principally the brain, spinal cord, nerves, and ganglia.

Detailed explanation-2: -Although the sensory systems associated with these senses are very different, all share a common function: to convert a stimulus (such as light, or sound, or the position of the body) into an electrical signal in the nervous system. This process is called sensory transduction.

Detailed explanation-3: -The transmission of any message in the neurons of our body requires it to be in the form of an action potential; the sensation must undergo conversion into electrical signals. The structures which convert mechanical signals into electrical signals are receptors.
