WEBApr 29, 2023 · A simple reflex arc has the following parts: 1. Stimulus. It is any change in the environment (internal or external) detected by a receptor. It initiates a response known as the reflex. It can be anything like a heat or cold sensation, an electron shock, and touching a sharp object. 2. Receptor.

Reflex arc - Wikipedia
https://en.wikipedia.org/wiki/Reflex_arc
WEBA reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain. The brain will receive the input while the ...
