Introduction

The nervous system of human beings performs several functions of utmost importance for the perfect functioning of the organism. In addition to performing specific tasks, the nervous system acts in conjunction with other organs of the human body, assisting them in their functioning.

Sensitive Functions

Stimuli and various kinds of information are captured by sensory receptors (also known as receptor or afferent neurons) in our body. A wound on the skin, an inflammation, an increase and decrease in external temperature and even a simple scratch are caught by these receptors. Sensory neurons almost instantaneously carry this information and stimuli to the brain and or spinal cord.

Integrating Functions

Specific nerve cells, especially interneurons (also known as connector neurons), perform the analysis, processing and storage of these stimuli and information captured by sensory receptors. These cells also act in preparing an organism response to the situation that is occurring.

Motor Functions

It is the last step of the nervous system process for a stimulus. It is the response of the nervous system, which is performed by motor neurons (also known as efferent or effector neurons). Effector cells and organs, which are in contact with motor neurons, receive information from the brain and perform an action according to the situation that is occurring.

Summary and Example

In a nutshell the nervous system receives the stimulus, analyzes and processes the information, sending it to the brain. Shortly thereafter, performs an action in favor of the body. Interestingly, this whole process takes place in milliseconds. This is all that happens when we touch a hot pan, feel the pain, and take it away immediately.
