A reflex arc, then, is the pathway followed by nerves which (a.) carry sensory information from the receptor to the spinal cord, and then (b.) carry the response generated by the spinal cord to effector organs during a reflex action. The pathway taken by the nerve impulse to accomplish a reflex action is called the reflex arc.
Triceps reflex — jerking of the forearm when the triceps tendon is hit with a tendon hammer, stimulating the C7 and C6 reflex arcs. Vagovagal reflex — contraction of muscles in the gastrointestinal tract in response to distension of the tract following consumption of food and drink. Vestibulocollic reflex; Vestibulo-spinal reflex
English: Explicative diagram of reflex arc; the journey takes energy and nerve impulse of a stimulus by two or more neurons.The spinal cord(3) receives sensory impulses of the body(2)- here his finger and sent to the central nervous system (afferent pathways(4), which sends impulses to the spinal motor (efferent(5)that sends turn-here the bodies arm muscle through spinal nerves(6).
The withdrawal reflex (nociceptive flexion reflex or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. [1] The reflex rapidly coordinates the contractions of all the flexor muscles and the relaxations of the extensors in that limb causing sudden withdrawal from the potentially damaging stimulus. [2]
B.Sensory Neurons C.Spinal Column D.Interneuron E.Motor Neuron F.Muscle G.Bone In a reflex arc, an action potential never travels to the brain for processing and so results in a much quicker reaction. When a stimulus (pain) is encountered, the signal from that stimulus will travel up the sensory neuron to the spinal column.
A diagram illustrating crossed extensor reflex. The crossed extensor reflex or crossed extensor response or crossed extension reflex is a reflex in which the contralateral limb compensates for loss of support when the ipsilateral limb withdraws from painful stimulus in a withdrawal reflex. [1]

The triceps reflex, a deep tendon reflex, is a reflex that elicits involuntary contraction of the triceps brachii muscle. It is sensed and transmitted by the radial nerve . [ 1 ] The reflex is tested as part of the neurological examination to assess the sensory and motor pathways within the C7 and C8 spinal nerves .
