Muscle - Jawed Fishes, Contraction, Movement: The sharks and other cartilaginous fishes (the class Chondrichthyes) have modified the structure of the first two arches; the cartilages of the anterior arch form the mandible and upper jaw (palatoquadrate),
within a muscle fiber and is responsible for all types of movements in animals. From the delicate jump of a cat onto the countertop to the full force speed of an elephant, or the dexterity of a human typing, muscle contraction is responsible for all of this. Muscle contraction allows for:...
(increased tone, spasticity, co-contraction) has been removed. For example, when a person with a brain injury is treated for spasticity, the tone in the affected limbs will be reduced and an apparentflexion contracturemay disappear. Conversely, some joint contractures may persist in these ...
The effect of a contralateral contraction on maximal voluntary activation and central fatigue in elbow flexor muscles A long-duration, submaximal contraction of a hand muscle increases central fatigue during a subsequent contraction in the other hand. However, this 'cross-... G Todd,NT Petersen,JLT...
1.a tissue composed of elongated cells, the contraction of which produces movement in the body. 2.a specific bundle of such tissue. 3.muscular strength; brawn. 4.power or force, esp. of a coercive nature:They put muscle into their policy and sent the marines. ...
In this study the effect of muscle fatigue on the cervical spine flexion–relaxation response was studied. Twenty healthy participants (10 males and 10 females) were recruited for data collection. The Sorenson protocol was utilized to induce neck muscle fatigue. Surface electromyography and optical mo...
From a theoretical standpoint, skeletal muscle is a primary driver of the relationship between body composition, bone health, and clinical outcomes, as it is involved in mobility, strength, and balance. However, while muscles play a vital role in human h
Thus, maximal isometric voluntary contraction, series elastic stiffness during wrist flexion and wrist extension, and wrist flexibility were investigated in healthy sedentary subjects and in women volley-ball players. Maximal isometric contraction and flexibility were measured classically with specific ...
In subject area: Medicine and Dentistry An eccentric contraction is one in which muscle tension increases in a muscle as it contracts to resist a force that attempts to overstretch the muscle's length. From: Clinics in Podiatric Medicine and Surgery, 2006 ...
An investigation was made of the influence of age and sex on peak muscle in knee extension and flexion during maximal isokinetic and isometric contraction... O Borges - 《Scandinavian Journal of Rehabilitation Medicine》 被引量: 382发表: 1989年 Bilateral...
