The upper motor neuron syndrome represents the lesion of upper motor neuron which leads to the absence of inhibition and to disorder of the reflex arc with spasm.
The reflex arc of the hiccup has 3 components: the afferent limb composed of phrenic, vagus, and sympathetic nerves; a central processor in the midbrain; and the efferent limb composed of the phrenic nerve supplying the diaphragm and intercostal nerves supplying the intercostal muscle fibers [3].
[4] Peripheral nerve blocks have been shown to be an effective way of reducing spasticity by interrupting the stretch reflex arc. [5]
It is used to assess the spinal reflex arc having ascending Ia afferent activity, the synapse at spinal level, and the descending homonymous motor nerve efferent activity (a motor neuron) to the muscle.
(32) He criticized the reflex arc, a model that reduces behavior to discrete and separate stimulus and response observed in situations similar to a child quickly withdrawing (response) his or her hand from a flame (stimulus).
we have a new and unusual reflex arc" and that the phenomenon occurs with sufficient frequency and regularity to demand an inquiry as to its nature Twitmyer, 1974, p.
Loss of inhibitory control from the brain via the spinal cord leads to uninhibited excitation of the monosynaptic spinal reflex arc. [5] The muscles, therefore, fire on their own, which causes spasticity.
Dry eye syndrome, a disease that is reported to affect over 30% of the population over 50 years of age, can be the result of an altered or inadequate tear film and it is thought to be associated with poor regulation of tear production via these sensory neurons in the tear reflex arc. (16-17) Ocular surgery, particularly laser refractive surgery, can negatively affect the ocular surface and tear film dynamics resulting in dry eye syndrome.
Reflex arc is the physiological response to the action of a stimulus that acts on a specific receptor field and has an anatomical substrate called reflex arc (fig 4).
The difference began with a disagreement that Bode had with Dewey's view of the psychological reflex arc. The disagreement enabled Bode to conceive of subject matters as more important to decision making than Dewey had.
Nerve growth factor (NGF) is one of the neurotrophic factors implicated, a known mediator of C fiber nerve excitability and bladder reflex arc reconstruction following SCI [12].
