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 ...

webreflex arc, neurological and sensory mechanism that controls a reflex, an immediate response to a particular stimulus. The primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action. The ...

webApr 29, 2023 · Reflex Arc. A signal travels from the organ and initiates a response to the organ that reacts to the signal. This response causes various parts of the reflex arc to work in order. A simple reflex arc has the following parts: 1. Stimulus. It is any change in the environment (internal or external) detected by a receptor.

webThe muscle stretch reflex is a reflex arc that responds to stretching of muscle fibers to keep the muscle in an appropriate state of tension and tone, ready to contract or relax as needed. The sensory input (afferent) of the reflex is from two structures in the muscle called spindles and Golgi tendon organs .

webIn its simplest form, a reflex is viewed as a function of an idealized mechanism called the reflex arc. The primary components of the reflex arc are the sensory-nerve cells (or receptor s) that receive stimulation, in turn connecting to other nerve cells that activate muscle cells (or effectors), which perform the reflex action.
