| 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) |

| paradoxical reflex | Any reflex in which the usual response is reversed or does not conform to the pattern characteristic of the particular reflex. Synonym: inverted reflex. (05 Mar 2000) |
| paradoxical triceps reflex | Flexion of the forearm caused by tapping the olecranon. Synonym: paradoxical triceps reflex. (05 Mar 2000) |
| venorespiratory reflex | Stimulation of respiration and increased pulmonary ventilation in response to an increase in pressure in the right atrium. (05 Mar 2000) |

| vertebra prominens reflex | Pressure upon the last cervical vertebra of an animal, especially of one whose labyrinths have been destroyed and the vestibular nuclei isolated, causes relaxation or reduced tone of all four limbs. (05 Mar 2000) |
| rectal reflex | The entrance of faecal matter into the rectum from the sigmoid colon causes an impulse to defecate. (05 Mar 2000) |
| rectocardiac reflex | A parasympathetic reflex producing bradycardia and hypotension upon stimulation of the pelvic nerve, the afferent limb being the sacral outflow of the parasympathetic division of the autonomic nervous system, and the efferent limb, the cardiac vagus; said to accompany proctologic examinations.

| vesical 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) |
| mass reflex | In cases of gross injury to the spinal cord, as the stage of reflex activity follows the primary flaccidity of the shock, a condition arises in which a strong stimulus to any part of one of the paralysed limbs will be followed by contraction of the hip, knee, and ankle of the same side and often, when the stimulus is applied to the middle line of the body, of both sides, as well as of the abdominal wall, and even evacuation of the bladder and sweating over an area corresponding to the level of the lesion.

| red reflex | A triangular area at the anterior inferior part of the tympanic membrane, running from the umbo to the periphery, where there is seen a bright reflection of light.

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. (05 Mar 2000) |
| vestibular ocular reflex | <clinical sign> Reflex movement of the eyes in the opposite direction to that which the head is moved, e.g., the eyes being lowered as the head is raised, and the reverse (Cantelli's sign); an indication of functional integrity of the brainstem tegmental pathways and cranial nerves involved in eye movement. Synonym: vestibular ocular reflex. (05 Mar 2000) |
