The types of reflexes will be discussed after we make you familiar about a reflex or reflex action. Reflex is an involuntary or instantaneous action by our body parts in response to a stimulus. It is due to the numerous neural pathways known as reflex arcs that act on an impulse before it reaches the brain. For reflex to occur, there is no requirement of any conscious thought or awareness about the automatic response. When a specialized tissue is receiving a stimulus, it may either directly or indirectly change the relation of other tissue or also the whole individual to the environment from where that stimulus arises. A few examples of the reflex action are the pupil of the eye changing its size where light acts as a stimulus; withdrawing our hands or legs suddenly when we touch something very hot and coughing or sneezing when dust or foreign particles enter our nasal passages. Our reactions are instantaneous, quick and involuntary in these situations. It doesn’t require much of a thinking process and the action is called the reflex action. And here, the mechanism of reflex includes the roles of spinal cord and the nerve pathway, involved in this action including a sensory nerve, a synapse, and a motor nerve, which altogether is termed as reflex arc. 

There are several ways to classify the reflexes of the body. Following are the classification of reflexes.

This is based on the movement of the organs or parts of the body that move due to the reflex. Some reflexes that move the skeletal muscles are extensor, flexor, locomotor and statokinetic. Reflexes that involve the function of internal organs include cardiovascular, digestive, secretory and excretory.

Reflexes can also be classified based on the degree of complexity of the neuron or  nerve organization within the reflex arcs. Under this category, these can be monosynaptic or monosegmental reflexes that involve only one segment of the central nervous system and multisynaptic or intersegmental reflexes that involve more than one segment of the central nervous system.

Reflexes can be innate reflexes and acquired reflexes where the former includes genetically determined and the latter type includes learned reflexes.

Reflexes can be somatic reflexes that control skeletal muscle contractions and include superficial and stretch reflexes; the other one includes visceral or autonomic reflexes.

Different types of reflex actions are known which are involuntary responses of effectors to the stimulus. It aids us in protection from any sudden stimulus that may harm us and therefore takes care of the survival of an organism. The significance of reflex action is due to the fact that reflex arcs are composed of major components creating a reflex. The function of each of these components is explained below-

We have briefly explained some reflex action examples in humans in the following points:

Reflex is the involuntary action of body parts in response to a stimuli. It occurs with the help of a reflex arc which is a nerve pathway via which varied components like receptor, interneuron, sensory neuron and effector work together to generate a reflex action. It is a five step process by which they generate a reflex action.

A multisynaptic reflex involves more than one neuron or interneurons within the reflex arc process. It works together with more than one area of the central nervous system, mainly the brain and the spinal cord. An example of such kind of reflex is flexor reflex.

Monosynaptic or monosegmental reflex involves only one segment of the central nervous system.

The different types of reflexes depend upon varied factors such as type, function, degree of complexity, development and response. The different reflexes may include  extensor, flexor, locomotor and statokinetic. Two types of reflex arcs are the autonomic reflex arc that affects inner organs, and the other type is the somatic reflex arc that affects muscles.
