Reflexes are categorized based on their complexity and the part of the nervous system they involve: Reflex Arc - an overview | ScienceDirect Topics
: Transmits the electrical impulse from the receptor toward the central nervous system (the spinal cord). RefleX
: Detects the stimulus (e.g., heat, pressure, or a pinprick). Reflexes are categorized based on their complexity and
: 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. This step bypasses the conscious part of the
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:
: Carries the response signal away from the central nervous system to the target organ.
