| Chodzko's reflex | Contractions of several muscles of the shoulder girdle and arm when the manubrium sterni is percussed. (05 Mar 2000) |
| metatarsal reflex | Flexion of the toes on tapping over the cuboid bone; almost identical with Guillain-Barre reflex, and fundamentally similar to Rossolimo's reflex. Synonym: metatarsal reflex. (05 Mar 2000) |
| Guillain-Barre reflex | Plantar flexion of the foot and toes elicited by tapping the sole near its outer edge; has the same significance as the Rossolimo toe flexion reflex Also called Guillain-Barre, Weingrow's, or sole tap reflex. Synonym: Guillain-Barre reflex, sole tap reflex, Weingrow's reflex. (05 Mar 2000) |
| gustatory-sudorific reflex | Sweating, especially over the face, when chewing food. See: auriculotemporal nerve syndrome. (05 Mar 2000) |
| Roger's reflex | Salivation caused by irritation of the lower end of the oesophagus, as by carcinoma. Synonym: Roger's reflex. (05 Mar 2000) |
| rooting reflex | When the cheek or lip is touched, a newborn baby automatically roots and turns the face toward the stimulus. The rooting reflex helps with breast-feeding. (12 Dec 1998) |
| pharyngeal reflex | The act of swallowing (second stage) induced by stimulation of the palate, fauces, or posterior pharyngeal wall. Synonym: deglutition reflex, pharyngeal reflex. (05 Mar 2000) |
| Rossolimo's reflex | Flicking the tops of the toes from the plantar surface causes flexion of the toes; a stretch reflex of the flexors of the toes seen in lesions of the pyramidal tracts. See: Starling's reflex. Synonym: plantar muscle reflex, Rossolimo's sign. (05 Mar 2000) |
| phasic reflex | A coordinated complex response such as the scratch reflex in the spinal animal. (05 Mar 2000) |
| Phillipson's reflex | A contraction of the extensors of the knee when the extensors of the opposite knee are inhibited. (05 Mar 2000) |
| ciliospinal reflex | Dilation of the pupil following scratching of the skin of the neck. Synonym: ciliospinal reflex, cutaneous pupil reflex, cutaneous-pupillary reflex, skin-pupillary reflex. (05 Mar 2000) |
| micturition reflex | Contraction of the walls of the bladder and relaxation of the trigone and urethral sphincter in response to a rise in pressure within the bladder; the reflex can be voluntarily inhibited and the inhibition readily abolished to control micturition. Synonym: bladder reflex, urinary reflex, vesical reflex. (05 Mar 2000) |
| milk-ejection reflex | Release of milk from the breast following tactile stimulation of the nipple; the afferent path is postulated to exist from the nipple to the hypothalamus; the efferent limb is represented by the neurohypophysial release of oxytocin into the systemic circulation; contraction of myoepithelial elements within the breast, caused by oxytocin, moves milk into the collecting ducts and toward the nipple. Synonym: let-down reflex, milk let-down reflex. (05 Mar 2000) |
