| radioperiosteal reflex | With the arm supinated to 45 |
|---|---|
| magnet reflex | A reaction seen in an animal deprived of its cerebellum; when the animal is placed upon its back and the head strongly flexed, the four limbs become flexed in all their joints. Due to stimulation of receptors in the deep layers of the skin, light pressure made upon a toe-pad with the finger causes reflex contraction of the limb extensors; the limb is thus pressed gently against the finger, and when the finger is withdrawn slightly, the experimenter has the sensation that his finger is raising the limb or drawing it out as by a magnet.

| palmar reflex | Flexion of the fingers following tickling of the palm. (05 Mar 2000) |
| palm-chin reflex | Unilateral (sometimes bilateral) contraction of the mentalis and orbicularis oris muscles caused by a brisk scratch made on the palm of the ipsilateral hand. Synonym: palm-chin reflex. (05 Mar 2000) |
| palmomental reflex | Unilateral (sometimes bilateral) contraction of the mentalis and orbicularis oris muscles caused by a brisk scratch made on the palm of the ipsilateral hand. Synonym: palm-chin reflex. (05 Mar 2000) |
| vasopressor reflex | Vasoconstriction caused by stimulation of certain afferent fibres, e.g., in vagus nerve. (05 Mar 2000) |
| gastrocolic reflex | A mass movement of the contents of the colon, frequently preceded by a similar movement in the small intestine, that sometimes occurs immediately following the entrance of food into the stomach. (05 Mar 2000) |
| gastroileac reflex | Opening of the ileocolic valve induced by entrance of food into the stomach. (05 Mar 2000) |
| Geigel's reflex | In the female, a contraction of the muscular fibres at the upper edge of Poupart's ligament on gently stroking the inner side of the thigh; analogue of the cremasteric reflex in males. (05 Mar 2000) |
| mandibular reflex | A spasmodic contraction of the temporal muscles following a downward tap on the loosely hanging mandible. Synonym: chin jerk, chin reflex, jaw jerk, mandibular reflex, masseter reflex. (05 Mar 2000) |
| parachute reflex | The reflex response of an infant (contraction of the limb and neck muscles) when allowed to drop a short distance through the air or startled by a sudden noise or jolt. Synonym: Moro reflex, parachute reflex, startle reaction. Synonym: cochleopalpebral reflex. (05 Mar 2000) |
| paradoxical extensor reflex | <clinical sign> Extension of the great toe and abduction of the other toes instead of the normal flexion reflex to plantar stimulation, considered indicative of pyramidal tract involvement ("positive" Babinski). Synonym: Babinski reflex, Babinski's phenomenon, great-toe reflex, paradoxical extensor reflex, toe phenomenon. (05 Mar 2000) |
| paradoxical flexor reflex | Dorsal flexion of the great toe produced by firm lateral pressure on the calf muscles. Synonym: paradoxical flexor reflex. (05 Mar 2000) |
| paradoxical patellar reflex | A tap on the patellar tendon causes contraction of the adductor, sudden passive extension of the leg causes a contraction of the extensor muscles of the leg. (05 Mar 2000) |
| paradoxical pupillary reflex | A pupillary response to light, the reverse of that expected; e.g., contraction of the pupil in response to turning the lights off. Synonym: Flynn phenomenon, paradoxical pupillary phenomenon. (05 Mar 2000) |
