WebIf the speed of the movement was increased fewer spindle discharges were seen during muscle shortening. If the shortening contraction was opposed by an external load, so that greater effort was required to perform the same movement, more discharges were seen and the discharge pattern became less modulated by the change in muscle length. 3. WebWhich of the following terms are NOT used interchangeably? motor unit - motor neuron Which of the following is NOT a phase of a muscle twitch? shortening phase Where does the acetylcholine that stimulates muscle contraction bind? receptors in the motor end plate When acetylcholine binds to its r

Difference Between Contraction and Constriction

WebMuscle contraction is the activation of tension-generating sites within muscle cells. In physiology, muscle contraction does not necessarily mean muscle shortening … Webmuscle during the contraction. Clearly, if an isometric or lengthening action or condition occurs, the muscle cannot be shortening during the contraction and any reference to shortening is simply redundant. In actu-ality, investigators have been modifying contraction with adjectives that are at odds with a definition of WebBoth ends of the muscle bulge connect to the bone with a tendon. If the muscle bulge contracts, it transfers the tension onto the tendon, which in turn transfers the tension onto … ps8190 march 2016 fillable
