Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

The single-fiber twitch experiments shown here were generated by stimulating the muscle cell membranes to threshold with an electrode and measuring the resulting action potential and force. How would the results differ if Ca21 were removed from the extracellular solution just before the electrical stimulus was applied?
The motor unit firing patterns are measured in a human hand muscle using an electromyography (EMG) recording. Which one of the following statements is the best description of the EMG pattern observed as the individual voluntarily attempts to make a low-level force of contraction in the muscle and steadily increases the force of contraction? Low amplitude spikes visible on the EMG trace at low force. Larger amplitude spikes become visible with increasing force of contraction. Low frequency of small amplitude spikes on the EMG trace at low force. Spike frequency and amplitude increase with increasing force. A large single deflection in the trace as the individual contracts the muscle. The deflection gets larger with increasing force. Low frequency of spikes on the EMG trace at low force. The frequency of spikes becomes more frequent with increasing force.

The sliding-filament model of skeletal-muscle contraction assumes a sliding or slipping of interdigitating filaments of actin and myosin. Electron micrographs show that during contraction the actin and my-osin filaments remain of constant length while the distance between Z lines shortens.
