What is the reflex arc?

The reflex arc refers to the sequence of events since the body receives external stimuli until it reacts to it.

In general terms,

1. a stimulus of varying nature reaches the body,

2. the peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-.

3. The CNS processes the information and sends another signal as a response to the stimulus.

This mechanism is known as the reflex arc, and it is composed of five elements,

- Receptors,

- Three types of neurons,

1. Afferent or sensorial neurons
2. Interneurons
3. Efferent or motor neurons

- Effectors.
