What is statokinetic reflexes?
[ stăt′ō-kĭ-nĕt′ĭk, -kī- ] n. A reflex that, through stimulation of the receptors in the neck muscles and semicircular canals, brings about movements of the limbs and eyes appropriate to a given movement of the head.
What are static reflexes?
A reflex concerned with establishing and maintaining posture when the body is at rest.
What is statokinetic?
: of, relating to, or constituting a kinetic postural reflex that is initiated by stimulation of the semicircular canals through movements of the head and involves compensatory movements of the limbs and eyes the effect of statokinetic stimuli on pilots during training flights — compare statotonic.
What is negative supporting reflex?
described by Magnus, who distinguished two types: positive supporting reactions, consisting of those reflex muscular contractions whereby the body is supported against gravity; seen in an exaggerated form in the decerebrate animal; negative supporting reactions, consisting of inhibition of the extensor muscles and …
What is a stretch reflex?
The stretch reflex or myotatic reflex refers to the contraction of a muscle in response to its passive stretching by increasing its contractility as long as the stretch is within physiological limits.
What is the purpose of the crossed extensor reflex?
The crossed extensor reflex or crossed extensor response or crossed extension reflex is a reflex in which the contralateral limb compensates for loss of support when the ipsilateral limb withdraws from painful stimulus in a withdrawal reflex.
