| bregmocardiac reflex | In infants, pressure upon the anterior fontanelle causing cardiac slowing. (05 Mar 2000) |
|---|---|
| Brissaud's reflex | Tickling the sole causes a contraction of the tensor fasciae latae muscle, even when there is no responsive movement of the toes. (05 Mar 2000) |
| bulbocavernosus reflex | A sharp contraction of the bulbocavernosus and ischiocavernosus muscles when the glans penis is suddenly compressed or tapped. (05 Mar 2000) |
| bulbomimic 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) |
| Capps' reflex | An obsolete eponym for vasomotor collapse at the time of crisis in pneumonia. (05 Mar 2000) |
| cardiac depressor reflex | A fall in blood pressure due to peripheral vasodilation and cardiac inhibition by stimulations of terminations of a cardiac depressor nerve in the aortic arch and base of the heart. Synonym: aortic reflex, depressor reflex. (05 Mar 2000) |
| gag reflex | Contact of a foreign body with the mucous membrane of the fauces causes retching or gagging. Synonym: faucial reflex. (05 Mar 2000) |
| 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) |
| palatal reflex | Swallowing reflex induced by stimulation of the palate. (05 Mar 2000) |
| 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.
