GENERAL HISTOLOGY

Detailed explanation-1: -It is called a reflex action. Thus an automatic, spontaneous and mechanical response to a stimulus controlled by the spinal cord without the involvement of the brain is called a reflex action.

Detailed explanation-2: -There are many different types of reflexes, but the most basic is called a simple reflex. A simple reflex contains only one space where information in the spinal cord travels between two nerve cells, called neurons.

Detailed explanation-3: -It is the processing unit for reflex actions because all nerves from various parts of the body meet at spinal cord before reaching the brain.

Detailed explanation-4: -A reflex action is an involuntary and nearly instantaneous movement in response to a stimulus.

Detailed explanation-5: -The reflex arc doesn’t involve the brain. Reflexes do not involve the conscious part of the brain, and the reflex arc therefore just runs through the spinal cord, not the brain. Reflexes are therefore rapid and automatic.
