n. the neural path of a reflex
Wikipedia
A reflex arc is a neural pathway that controls a reflex action. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the reflex is carried out. Analysis of the signal takes place after action has been taken.
There are two types of reflex arc: autonomic reflex arc (affecting inner organs) and somatic reflex arc (affecting muscles).
It is the pathway followed by sensory nerve in carrying the sensation from receptor organ to spinal cord and then the pathway followed by motor nerve in carrying the order from spinal cord to effector organ during a reflex action.
Usage examples of "reflex arc".
The nerve cell connections along which the nerve impulse travels from initial sensation to final response is the reflex arc.
The simplest possible reflex arc is one consisting of two neurons, the sensory and the motor.
This is basically a reflex arc, like the knee-jerk, although involving rather more complex circuitry.
As all Teachers had to, she'd gone through the testers' hands when she was hired, and they'd reported a high level of e-wave activity, indicating more than one psi capacity, along with aberrant neurophysiological response in the autonomic system, primarily in reflex arc synaptic time.
