Neuromuscular disorders leads to loss of muscle function because they affect the musculature and/or the nervous system. Etiology could be due to autoimmune disorders, genetic/hereditary disorders. The process of mastication is controlled and coordinated by a well-defined neurological system which primarily consists of skeletal muscles, motor and sensory nerve fibers. This neuromuscular control involves in every phase of complete denture prosthesis construction. Skeletal muscles directly play a vital role in complete denture prosthesis function. A good muscular control and coordination is neces

✓ Misdirection of sensory fibers into motor pathways is, in part, responsible for the poor results obtained after peripheral nerve repair. After avulsion of the C-5 root in rats, the authors connected a C-4 ventral rootlet to the musculocutaneous nerve by means of a sural nerve graft. In this way, they were able to increase the number of regenerating motor fibers and avoid growth of sensory fibers into the nerve grafts. Functional recovery was evaluated electrophysiologically and histologically. The origin of the axons that reinnervated the nerve graft was analyzed by means of morphological st

Each human lower limb contains over 50 muscles that are coordinated during locomotion.

Joint position sense is believed to be mediated by muscle afferent signals. Because a “phantom” hand produced by a sensory and motor nerve block appears to move in the direction of voluntary effort, signals of “motor command” or “effort” can influence perceived joint position. To determine whether this occurs when sensory signals are available, three studies assessed position sense when motor command and afferent signals were available, but joint movement was prevented. First, the hand was positioned to stop movement at the proximal joint of the middle finger, and movement at the distal joint

The rhythmic motor activity of the vibrissae that rodents use for the tactile localization of objects provides a model system for understanding patterned motor activity in mammals.

As a means to characterize the pattern of muscular dynamics during different patterns of whisking, we recorded electromyogram (EMG) activity from the muscles that propel individual follicles, as well as EMG activity from a muscle group that moves the mystacial pad.

The decrease in tone of antigravity muscles, in turn, is triggered by the deficit and distortion of gravity-specific sensory input from tactile mechanoreceptors and otoliths.

Background: Blood flow restriction (BFR) therapy is a technique that uses partial occlusion of arterial blood flow in tandem with low-load resistance training to promote an environment of metabolic stress within muscle tissue. It is hypothesized that such therapy can facilitate protein synthesis and muscle hypertrophy even in the setting of age, injury, or postoperative rehabilitation—conditions which are marred by muscle atrophy and progressive loss of function. Therefore, BFR may be a successful option to facilitate strength gains even in patients unable to perform traditional high-load resi

In obstructive sleep apnea (OSA), the short-latency inhibitory reflex (IR) of inspiratory muscles to airway occlusion is prolonged in proportion to the severity of the OSA. The mechanism underlying the prolongation may relate to chronic inspiratory muscle loading due to upper airway obstruction or sensory changes due to chronic OSA-mediated inflammation. Continuous positive airway pressure (CPAP) therapy prevents upper airway obstruction and reverses inflammation. We therefore tested whether CPAP therapy normalized the IR abnormality in OSA.

When oxygen delivery to active muscle is too low for the ongoing rate of metabolism, metabolites accumulate and stimulate sensory nerves within the muscle leading to sympathetic activation (muscle chemoreflex). To date, studies on this reflex have focused primarily on its ability to increase arterial pressure or on the activity of the nerves that mediate this response. Clearly, a rise in cardiac output (CO) constitutes an important adjustment, because it increases the total blood flow available to be distributed among organs competing for flow. However, increments in heart rate and contractili

Moreover, the observable sensory inputs are delayed and there are typically multiple solutions to solve a motor task (e.g. Franklin &amp; Wolpert, 2011).

Sensory receptors, afferent fibers, and spinal ascending pathways involved in somatosensory inhibition of baroreflex vagal bradycardia (BVB) were studied in chloralose-urethan-anesthetized rats. BVB was induced by electrical stimulation of the aortic depressor nerve (ADN). Among mechanical and thermal stimuli applied on a hindlimb, hot water (55 degrees C) immersion was most effective to inhibit BVB. Static hindlimb muscle contraction by ventral root stimulation also produced BVB inhibition that was abolished by muscle relaxation. These findings suggest that thermal nociceptors and muscle rece

Fusion was made possible by means of prisms that moved the images of targets in central vision to the threshold of fusion in the primary eye position.
