A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons synapse in the spinal cord and the signal then travels through...

The pharyngeal reflex is different from the laryngeal spasm, which is a reflex muscular contraction of the vocal cords. In a reflex arc, a series of physiological...

response to surrounding tissue. The axon reflex arc is distinct from the spinal cord reflex arc. In the spinal cord reflex pathway the afferent neuron transmits...

signals to the spinal cord along a sensory neuron. Within the spine, a reflex arc switches the signals straight back to the muscles of the arm (effectors)...

Biceps reflex is a deep tendon reflex (DTR) test (also known as a muscle-stretch reflex test) that examines the function of the C5 reflex arc and the C6...

in organisms with a nervous system. A reflex occurs via neural pathways in the nervous system called reflex arcs. A stimulus initiates a neural signal...

the reflex arc to suppress extensor withdrawal results in the upgoing toes in the plantar reflex known as Babinski's sign. The Hoffmann's reflex is sometimes...

contraction of the triceps muscle causes extension, and indicates a normal reflex. The arc involves the stretch receptors in the triceps tendon, from where the...

The Bainbridge reflex (or Bainbridge effect or atrial reflex) is a cardiovascular reflex causing an increase in heart rate in response to increased stretching...

jerk reflex — jerking of the ankle when the Achilles tendon is hit with a tendon hammer while the foot is relaxed, stimulating the S1 reflex arc. Arthrokinetic...

one of the founding thinkers of functional psychology. His paper "The Reflex Arc Concept in Psychology", published in 1896, is regarded as the first major...

inhibitory reflex (RAIR), also known as the anal sampling mechanism, anal sampling reflex, rectosphincteric reflex, or anorectal sampling reflex, is a reflex characterized...

This reflex may also be impaired by damage to the internal branch of the superior laryngeal nerve which relays the afferent branch of the reflex arc.[citation...

inflammatory reflex is a neural circuit that regulates the immune response to injury and invasion. All reflexes have an afferent and efferent arc. The Inflammatory...
