In mammalian spinal reflexes, large-diameter afferent fibers from muscle spindles (Ia) makes monosynaptic facilitation to the homonymous and synergist muscles, which is the main constituent of stretch reflex, and disynaptic inhibition to the antagonistic muscles (Fig.
Muscle groups, whether distal and proximal muscles, differ in the size of cortical representation, the extent of monosynaptic corticospinal projection (Pyndt et al., 2003), and the relative contribution of motor unit recruitment and modulation of discharge rate to the gradation of muscle force (Kukulka and Clamann, 1981).
Loss of inhibitory control from the brain via the spinal cord leads to uninhibited excitation of the monosynaptic spinal reflex arc.
Depending on the number of synapses interposed on the trajectory reflex arc, reflexes are monosynaptic and polysynaptic.
Monosynaptic reflexes are hyperactive, H-reflex and reciprocal inhibition are sustained.
Monosynaptic pathways provide an extremely rapid reflex feedback system and are the basis for the muscle stretch reflex.
(34) The H-reflex is produced when action potentials that travel proximally along sensory fibers enter the dorsal horn of the spinal cord and stimulate the monosynaptic reflex arc (Fig.
If the trunk and pelvis were indeed responsible for the triggering of the postural responses, one may expect segmental reflexes from the lumbar (ES muscle) to occur first through fast conducting monosynaptic stretch reflexes to maintain posture.
When that circuit, known as the monosynaptic circuit, was disrupted, the animals did not learn to fear the tone.
