'''Reflex''' is a simple, automatic response to a specific stimulus. Reflexes are involuntary, meaning that they occur without conscious control. They are a fundamental part of the body's ability to respond quickly to changes in the environment.

== Overview ==
A reflex is a rapid, involuntary response to a stimulus. It is a basic building block of the nervous system and is critical for survival. Reflexes can be simple, such as blinking when something comes close to the eye, or complex, such as the body's response to changes in temperature.

== Types of Reflexes ==
There are two main types of reflexes: [[autonomic reflexes]] and [[somatic reflexes]]. Autonomic reflexes control the activity of internal organs and glands, while somatic reflexes control skeletal muscle movements.

=== Autonomic Reflexes ===
Autonomic reflexes are those that involve the [[autonomic nervous system]]. They control the functions of our internal organs, such as the heart, stomach, and intestines. These reflexes are not under conscious control and are often involved in maintaining homeostasis.

=== Somatic Reflexes ===
Somatic reflexes are those that involve the [[somatic nervous system]]. They control voluntary muscle movements, such as moving your hand away from a hot stove. These reflexes are under conscious control and are often involved in responding to external stimuli.

== Reflex Arc ==
The pathway followed by a nerve impulse during a reflex is called a [[reflex arc]]. A typical reflex arc involves a sensory neuron, an interneuron, and a motor neuron. The sensory neuron detects the stimulus and sends a signal to the interneuron, which in turn sends a signal to the motor neuron, causing a response.

== Clinical Significance ==
Reflexes are often used in medical examinations to assess the health of the nervous system. Abnormal reflex responses can indicate a variety of conditions, including [[neurological disorders]], [[spinal cord injuries]], and [[peripheral neuropathy]].
