| righting reflexes | Reflex's which through various receptors, in labyrinth, eyes, muscles, or skin, tend to bring an animal's body into its normal position in space and which resist any force acting to put it into a false position, e.g., on its back. See: body righting reflexes, labyrinthine righting reflexes, neck reflexes, optical righting reflexes. Synonym: static reflexes. (05 Mar 2000) |

| proprioceptive reflexes | <physiology> Any reflex brought about by stimulation of proprioceptors. See: proprioceptor. (05 Mar 2000) |
| skin-muscle reflexes | Superficial or cutaneous reflex's, such as the superficial abdominal reflex's. Synonym: skin reflexes. (05 Mar 2000) |
| skin reflexes | Superficial or cutaneous reflex's, such as the superficial abdominal reflex's. Synonym: skin reflexes. (05 Mar 2000) |
| neck reflexes | Changes in position of the head cause alterations in tone of the neck muscles through stimulation of proprioceptors in the labyrinth which bring the head into its correct position in space; stimulation of proprioceptors in the neck muscles causes in turn reflex movements of the limbs which bring the animal into the normal position in relation to the head. (05 Mar 2000) |
| static reflexes | Responses that control the position of the trunk and extremities. See: righting reflexes. Synonym: static reflexes. (05 Mar 2000) |
| statotonic reflexes | Reflex's in which utricular receptors in the vestibular apparatus sense changes in the head's position in space in terms of linear acceleration and the earth's gravitational field while receptors in the neck muscles sense changes in the position of the head relative to the trunk; input from these receptors reflexly controls the tone of the limb muscles to maintain or regain the desired posture. Synonym: attitudinal reflexes. (05 Mar 2000) |
| deep abdominal reflexes | Contraction of abdominal muscles elicited by stimulation, such as tapping a deep structure; e.g., the costal margin. See: Galant's reflex, upper abdominal periosteal reflex. (05 Mar 2000) |
| optical righting reflexes | Visual stimuli that enable an animal to maintain the correct position of the head in space, by bringing about movements of the muscles of the neck and limbs. (05 Mar 2000) |
| utricular reflexes | See: statotonic reflexes. (05 Mar 2000) |
| labyrinthine reflexes | Reflex's initiated through stimulation of receptors in the utricle or saemicircular canals. See: statotonic reflexes, statokinetic reflex, righting reflexes. (05 Mar 2000) |
| labyrinthine righting reflexes | Stimulation of the proprioceptors of the labyrinth causes changes in tone of the neck muscles which bring the head into its natural position in space. (05 Mar 2000) |
