WebbOnce the muscle fibre is stimulated by the motor neuron, actin and myosin protein filaments within the skeletal muscle fibre slide past each other to produce a contraction. The sliding filament theory is the most widely accepted explanation for how this occurs. According to this theory, muscle contraction is a cycle of molecular events in which thick … WebbAs a result, bone surfaces rub against each other, causing severe discomfort.

8.4E: Synovial Joint Movements - Medicine LibreTexts
Synovial joints allow for a number of different types of body movements. There are six types of synovial joints found at different locations in the body. 1.

For a muscle cell to contract, the sarcomere must shorten. However, thick and thin filaments—the components of sarcomeres—do not shorten. Instead, they slide by one another, causing the sarcomere to shorten while the filaments remain the same length. darby cates
