| radial reflex | On tapping the lower end of the radius, flexion of the forearm occurs, and sometimes, on strong percussion, flexion of the fingers. See: inverted radial reflex. (05 Mar 2000) |
| Galant's reflex | A deep abdominal reflex in which there is a contraction of the abdominal muscles on tapping the anterior superior iliac spine. Synonym: lower abdominal periosteal reflex. (05 Mar 2000) |
| vagovagal reflex | Bradycardia with arterial hypotension, often with supraventricular arrhythmias; ascribed to stimulation, especially mechanical, of afferent vagal pathways in the abdomen, thorax, or airway, the efferent arc being vagal cardioinhibitory fibres. (05 Mar 2000) |
| galvanic skin reflex | A change in electrical resistance of the skin, occurring in emotion and in certain other conditions. (12 Dec 1998) |
| radiobicipital reflex | Contraction of the biceps muscle which sometimes occurs in the elicitation of the brachioradial reflex. (05 Mar 2000) |

| 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reflex contraction of the limb extensors; the limb is thus pressed gently against the finger, and when the finger is withdrawn slightly, the experimenter has the sensation that his finger is raising the limb or drawing it out as by a magnet.

| 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) |
