| 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) |
| milk let-down 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) |
| clasping reflex | The strong flexion of the forelimbs of amphibia and certain other animals during the mating season when the chest or abdomen is stimulated; it is dependent upon the male sex hormone. (05 Mar 2000) |
| cochleo-orbicular reflex | A form of the wink reflex in which there is a contraction, sometimes very slight, of the orbicularis palpebrarum muscle when a sudden noise is made close to the ear; it is absent in labyrinthine disease with total deafness. Synonym: acousticopalpebral reflex, auropalpebral reflex, cochleo-orbicular reflex, startle reflex. (05 Mar 2000) |
| cochleopalpebral reflex | A form of the wink reflex in which there is a contraction, sometimes very slight, of the orbicularis palpebrarum muscle when a sudden noise is made close to the ear; it is absent in labyrinthine disease with total deafness. Synonym: acousticopalpebral reflex, auropalpebral reflex, cochleo-orbicular reflex, startle reflex. (05 Mar 2000) |
| cochleopupillary reflex | Constriction of the pupil in response to a sudden loud sound. The normal response to such a stimulus is pupil dilation. (05 Mar 2000) |
| cochleostapedial reflex | Contraction of the stapedius muscle in response to a loud sound; this is a protective reflex which with the reflex contraction of the tensor tympani reduces the amplitude of the vibrations of the tympanic membrane and ossicles. (05 Mar 2000) |
| coeliac plexus reflex | Arterial hypotension coincident with surgical manipulations in the upper abdomen during general anaesthesia. (05 Mar 2000) |
| Mondonesi's reflex | In a case of coma from severe apoplexy, pressure on the eyeballs causes contraction of the facial muscles of expression on the side opposite to the lesion; if coma due to diabetes, uraemia, or other toxic cause the reflex is present on both sides. Synonym: facial reflex, Mondonesi's reflex. (05 Mar 2000) |
| pilomotor reflex | Contraction of the smooth muscle of the skin resulting in "gooseflesh" caused by mild application of a tactile stimulus or by local cooling. (05 Mar 2000) |
| pinch reflex diode | <radiobiology> A self-insulated ion diode in which the magnetic field from the ion and electron flow alone provide electron control, and the ion source is an anode plasma formed by relexing the electrons through a thin plastic foil. (09 Oct 1997) |
| Weingrow's 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) |
| Westphal's pupillary reflex | A constriction of both pupils when an effort is made to close eyelids forcibly held apart. A variant of the pupil response to near vision. Synonym: Galassi's pupillary phenomenon, Gifford's reflex, lid-closure reaction, orbicularis phenomenon, orbicularis pupillary reflex, Piltz sign, Westphal's pupillary reflex, Westphal-Piltz phenomenon.
