| stepping reflex | If the plantar surface of a hind foot of a dog is pressed gently, a movement of extension of the limb will follow, accompanied sometimes by flexion of the opposite hind limb. (05 Mar 2000) |
|---|---|
| sternobrachial reflex | Contraction of the adductors of the arm when the sternum is tapped. (05 Mar 2000) |
| stretch reflex | Tonic contraction of the muscles in response to a stretching force, due to stimulation of muscle proprioceptors. Synonym: Liddell-Sherrington reflex, muscular reflex, stretch reflex. (05 Mar 2000) |
| Strumpell's reflex | Stroking the abdomen or thigh causes flexion of the leg and adduction of the foot. (05 Mar 2000) |
| styloradial reflex | With the arm supinated to 45 |
| nociceptive reflex | Flexion of ankle, knee, and hip when the foot is painfully stimulated; the crossed extension reflex occurs in association with it. Synonym: defense reflex, nociceptive reflex, withdrawal reflex. (05 Mar 2000) |
| nocifensor reflex | Vascular dilation in a part surrounding an injury or in its neighborhood. (05 Mar 2000) |
| suckling reflex | The reflex liberation of prolactin from the anterior lobe of the hypophysis evoked by stimulation of nerves in the nipple during the act of suckling by the newborn animal. (05 Mar 2000) |
| nose-bridge-lid reflex | Contraction of the orbicularis oculi muscles upon tapping the margin of the orbit, or the bridge or tip of the nose. Synonym: nose-bridge-lid reflex, nose-eye reflex. (05 Mar 2000) |
| nose-eye reflex | Contraction of the orbicularis oculi muscles upon tapping the margin of the orbit, or the bridge or tip of the nose. Synonym: nose-bridge-lid reflex, nose-eye reflex. (05 Mar 2000) |
| darwinian reflex | The tendency of young infants to grasp a bar and hang suspended. Compare: grasping reflex. (05 Mar 2000) |

| decerebrate reflex | <neurology, physiology> Spontaneous extension of elbows, wrists and legs which suggests damage to the diencephalon (midbrain). Seen in cases of stroke and some cases of encephalitis. The decerebrate reflex is a clinical finding characterised by rigid contraction of the extensor and other muscles which maintain an animal in the standing position (antigravity muscles), may be seen in association with a severe stroke, intracranial haemorrhage, cerebral haemorrhage, cerebral toxin or transection of the brain below the level of the anterior corpora quadrigemina but above the vestibular nuclei, clinically may be preceded by decortication. (27 Sep 1997) |
| decorticate reflex | <neurology, physiology> Spontaneous flexion of the elbows with the legs extended. Accompanies severe damage to the contralateral cerebral hemisphere above the midbrain (for example stroke). The destruction of the cerebral cortex, usually due to anoxia, trauma or toxic insult, may proceed to decerebration (a more severe neurologic state). (27 Sep 1997) |
| supination reflex | With the arm supinated to 45 |
