Web18 de out. de 2014 · The stretch reflex is fast, with a latency (stimulus–response interval) of about 15–25 ms (contrast the polysynaptic withdrawal reflex with latency ~70-100 ms .) The stretch is initiated at the Golgi tendon organs. These are found at the junction between muscle and tendon.

Reflex arc Definition & Meaning - Merriam-Webster

WebKey Points. • Reflexes, or reflex actions, are involuntary, almost instantaneous movements in response to a specific stimulus. • Reflex arcs that contain only two neurons, a sensory and a motor neuron, are considered monosynaptic. • Monosynaptic refers to the presence of a direct single synapse; no interneuron is present. WebReflex arc Reflex actions. There are three main types of neuron: sensory, motor and relay. These different types of neurons work together in a reflex action. A 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 reflex is being carried out and the analysis of the signal takes place after the reflex action. d2 a good match
