The basic physiological principles of muscle contraction are well established ... The aim of this collection is to provide an overview of current advances in the development of quantitative ...

Isotonic contractions – these occur when a muscle contracts and changes length and there are two types: Isotonic concentric contraction – this involves the muscle shortening. The origin and ...

The insertion is the other end of the muscle that is attached to the bone which moves. Muscular contractions are defined as the change in the length of the muscle under contraction. Muscles ...

Muscle twitching is a general term for muscle contractions. Your muscles are made up of fibers that your nerves control. Stimulating or damaging a nerve can cause muscle fibers to twitch.

When muscle cells are viewed under the microscope, one can see that they contain a striped pattern (striations). This pattern is formed by a series of basic units called sarcomeres that are ...

The purpose of this study is to learn about and measure changes in muscle contraction that happen as healthy people age. The connection between electrical activity causing muscles to contract and the ...

When the facial nerve fires, the signal is directed to the ipsilateral facial muscles causing muscle contractions in different areas of the face on the same side. A competing hypothesis states that ...

Describes the nature of a clinical study. Types include: Observational study — observes people and measures outcomes without affecting results. Interventional study (clinical trial) — studies new ...

This chapter provides an overview of surface EMG decomposition techniques ... the electrical activity of several nearby muscle fibers that are active during a muscle contraction. The electrical ...
