Axon reflex
Encyclopedia
An Axon reflex is a response brought on by peripheral nerve stimulation. Examples include Vasodilation
originally described by Lewis as the "Hunter's Response
" or autonomic reaction to loss of body heat in the extremities (also known as "Lewis wave" and "Lewis reaction")..
Vasodilation
Vasodilation refers to the widening of blood vessels resulting from relaxation of smooth muscle cells within the vessel walls, particularly in the large arteries, smaller arterioles and large veins. The process is essentially the opposite of vasoconstriction, or the narrowing of blood vessels. When...

Hunter's Response
The Hunter's Response, also known as the Lewis wave, is a tendency for certain people in a cold environment, to periodically open to allow blood flow of capillaries of the extremities , when they might otherwise be constricted to preserve the body's core temperature...
