WebThe neurones of the reflex arc. There are three main types of neurone in a reflex arc: sensory, relay and motor. Sensory neurones carry impulses from sense organs to the CNS (brain or spinal cord); Relay neurones are found inside the CNS and connect sensory and motor neurones; Motor neurones carry impulses from the CNS to effectors (muscles or … WebApr 8, 2024 · A reflex, also known as a reflex action, is an involuntary movement that occurs in response to a stimulus. The reflex arc, a neural pathway that governs reflexes, is where reflex actions take place. The sense organ that detects danger is the receptor in this case. Sensory neurons receive information from the sensory organ and send them to …

WebDefinition. The neural network that manages a reflex is known as a reflex or simple reflex arc. In vertebrates, most sensory neurons synapse in the spinal cord rather than entering the brain directly. By activating the spinal motor neurons, faster reflex actions can be induced without waiting for signals to travel to the brain. WebFigure 2 Generalized reflex arc. Reaction time is the amount of time required for an individual to perceive and respond to a sensory stimulus (such as the act of swinging a bat at a baseball). The average reaction time for a visual stimulus is 200 to 250 ms; for hearing, 150 to 200 ms; and for touch, 130 to 170 ms.
