A neuromuscular disease is any disease affecting the peripheral nervous system (PNS), [a] the neuromuscular junctions, or skeletal muscles, all of which are components of the motor unit. [4] Damage to any of these structures can cause muscle atrophy and weakness. Issues with sensation can also occur. Neuromuscular diseases can be acquired or ...
A neuronopathy affects the cell body of a nerve cell in the peripheral nervous system. [5] Amyotrophic lateral sclerosis; Spinal muscular atrophy; Spinal muscular atrophy with respiratory distress type 1; Atypical motor neuron diseases; Dorsal root ganglion disorders
Among neuromuscular diseases some can be autoimmune disease, or hereditary disorders. They can affect either presynaptic mechanisms or postsynaptic mechanisms, preventing the junction from functioning normally. The most studied diseases affecting the human acetylcholine receptor are myasthenia gravis and some forms of congenital myasthenic ...
Motor disorders are disorders of the nervous system that cause abnormal and involuntary movements. They can result from damage to the motor system. [1]Motor disorders are defined in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) – published in 2013 to replace the fourth text revision – as a new sub-category of neurodevelopmental disorders.
The parallel muscle architecture is found in muscles where the fibers are parallel to the force-generating axis. [1] These muscles are often used for fast or extensive movements and can be measured by the anatomical cross-sectional area (ACSA). [3] Parallel muscles can be further defined into three main categories: strap, fusiform, or fan-shaped.
Nervous system diseases, also known as nervous system or neurological disorders, refers to a small class of medical conditions affecting the nervous system.This category encompasses over 600 different conditions, including genetic disorders, infections, cancer, seizure disorders (such as epilepsy), conditions with a cardiovascular origin (such as stroke), congenital and developmental disorders ...
NMT is a diverse disorder. As a result of muscular hyperactivity, patients may present with muscle cramps, stiffness, myotonia-like symptoms (slow relaxation), associated walking difficulties, hyperhidrosis (excessive sweating), myokymia (quivering of a muscle), fasciculations (muscle twitching), fatigue, exercise intolerance, myoclonic jerks and other related symptoms.
People with spastic quadriplegia are the least likely to be able to walk, or if they can, to want to walk, because their muscles are too tight and it is too much effort to do so. Some children with quadriplegia also have hemiparetic tremors, an uncontrollable shaking that affects the limbs on one side of the body and impairs normal movement.
