WebThese components form a basic circuit that is called a reflex arc. The control center portion of the reflex arc can be quite simple (as in the synapse of an afferent neuron onto an efferent neuron in a stretch reflex), but it is often more complex involving one or more interneurons. Simple reflexes involving a single synapse between two WebThe stretch reflex arc may be tested in human subjects by the application of fast stretch or vibration to the primary ending of the muscle spindle to produce a tendon jerk, or by the electrical stimulation of Ia afferent fibers in the appropriate peripheral nerve to evoke an H …

What is the importance of the reflex arc? Answer: A reflex arc is a neural pathway that controls a reflex. WebThe stretch reflex can be a monosynaptic reflex which provides automatic regulation of skeletal muscle length, whereby the signal entering the spinal cord arises from a change in muscle length or velocity. It can also include a polysynaptic component, as in the tonic stretch reflex. [2] hangouts sms on computer
