The axon reflex was discovered by Kovalevskiy and Sokovnin, two Russian scientists in 1873. They described the axon reflex as a new type of peripheral (or local) reflex where electrical signal starts in the middle of the axon and transmit immediately skipping both an integration center and a chemical synapse as … See more The axon reflex (or the flare response) is the response stimulated by peripheral nerves of the body that travels away from the nerve cell body and branches to stimulate target organs. Reflexes are single reactions that … See more Cutaneous receptors are sensory receptors in the skin that detect changes in temperature (thermoreceptors) and pain (nociceptors). These cutaneous receptors initiate an impulse via excitation of the main sensory axon to the spinal cord. The axon reflex is the … See more When a proximal impulse stimulates the stretch and heat receptors on one branch of a bifurcated axon, the produced signal moves backwards towards the point of axon bifurcation. The impulse then reflects down the other branch of the axon to the effector organ … See more • Axon • Thermoregulation • Hypothermia • Frostbite See more WebThe axon reflex (schematically shown in Fig. 84.1) occurs when ACh stimulates nicotinic receptors on the postganglionic sympathetic sudomotor axon. The evoked impulse travels antidromically, reaches a branch-point, and then travels orthodromically to mediate sweating by binding to M 3 muscarinic receptors on the gland itself.
