Crossed segmental inhibition in muscles.
Muscle spindles are critically involved in the reflex regulation of the dynamic and static actions of muscles; the sensitivity of the actions is under strong efferent control2, 8. In the usually studied mammal, the cat, the receptor elements in the muscle spindles convey by two types of fibers (Groups I and II) muscle displacement and velocity information to the central nervous system. The func...
متن کاملShort-latency crossed inhibitory responses in extensor muscles during locomotion in the cat.
During locomotion, contacting an obstacle generates a coordinated response involving flexion of the stimulated leg and activation of extensors contralaterally to ensure adequate support and forward progression. Activation of motoneurons innervating contralateral muscles (i.e., crossed extensor reflex) has always been described as an excitation, but the present paper shows that excitatory respon...
متن کاملPostnatal cytochemical development of muscle fibers in segmental tail muscles of the rat.
Postnatal development of extrafusal and intrafusal muscle fibers was examined histochemically in segmental tail muscles of the rat. At birth all fibers show a strong reaction for myosin ATPase, uniformity in diameter, and homogeneity in staining intensity. During the first postnatal week, the muscle fibers undergo gradual hypertrophy and hyperplasia but they all maintain the same intense homoge...
متن کاملAbnormal reciprocal inhibition between antagonist muscles in Parkinson's disease.
Disynaptic Ia reciprocal inhibition acts, at the spinal level, by actively inhibiting antagonist motor neurons and reducing the inhibition of agonist motor neurons. The deactivation of this pathway in Parkinson's disease is still debated. Disynaptic reciprocal inhibition of H reflexes in the forearm flexor muscles was examined in 15 control subjects and 16 treated parkinsonian patients at rest ...
متن کاملDurability Effects of Corrective Eexercise Program with Kinesiotaping and Physio Ball on EMG of Selected Shoulder Girdle Muscles in Boy with Upper Crossed Syndrome
Postural disorders disrupt muscle activity and lead to joint dysfunction. Maintaining the function of the shoulder joint requires precise coordination and on-time action of muscles, and its dysfunction lead to change in the level of muscle activity, movement disorder. This study aimed to measure the effects of corrective exercise program with kinesiotaping and physio-ball and durability of the...
