Reflex
: Transmits the electrical impulse from the receptor toward the central nervous system (the spinal cord).
: Carries the response signal away from the central nervous system to the target organ. RefleX
: Detects the stimulus (e.g., heat, pressure, or a pinprick). : Transmits the electrical impulse from the receptor
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: RefleX
: 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.
