There are two types of isotonic contractions: (1) concentric and (2) eccentric. In a concentric contraction, the muscle tension rises to meet the resistance, then remains the same as the muscle shortens. In eccentric, the muscle lengthens due to the resistance being greater than the force the muscle is producing. [citation needed]
Extrapyramidal symptoms (also called extrapyramidal side effects) get their name because they are symptoms of disorders in the extrapyramidal system, which regulates posture and skeletal muscle tone. This is in contrast to symptoms originating from the pyramidal tracts. [citation needed]
Abbreviations are used very frequently in medicine. They boost efficiency as long as they are used intelligently. The advantages of brevity should be weighed against the possibilities of obfuscation (making the communication harder for others to understand) and ambiguity (having more than one possible interpretation).
Depiction of smooth muscle contraction. Muscle contraction is the activation of tension-generating sites within muscle cells. [1] [2] In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. [1]
altered muscle tone (hypotonia or hypertonia) – a decrease or increase in the baseline level of muscle activity; decreased endurance; exaggerated deep tendon reflexes including spasticity, and clonus (a series of involuntary rapid muscle contractions) Such signs are collectively termed the "upper motor neuron syndrome".
Eponymous medical signs are those that are named after a person or persons, usually the physicians who first described them, but occasionally named after a famous patient. This list includes other eponymous entities of diagnostic significance; i.e. tests, reflexes, etc.
Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder.The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles and rigidity. [1]
