: Transmits the electrical impulse from the receptor toward the central nervous system (the spinal cord).
: Located within the spinal cord (or brainstem), where the signal is often passed to an interneuron (relay neuron). This step bypasses the conscious part of the brain for immediate action. RefleX
The pathway followed by the nerve impulses during a reflex action is called the . In a typical spinal reflex, this pathway usually consists of five core components: : Transmits the electrical impulse from the receptor
A is a rapid, automatic, and involuntary response to a specific stimulus. These actions are fundamental to survival because they allow the body to react nearly instantaneously to protect itself—such as pulling your hand away from a hot stove—before the brain even processes the sensation of pain. The Reflex Arc The pathway followed by the nerve impulses during
: Carries the response signal away from the central nervous system to the target organ.
Reflexes are categorized based on their complexity and the part of the nervous system they involve: Reflex Arc - an overview | ScienceDirect Topics
