The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement.
Muscle is a soft tissue, one of the four basic types of animal tissue. Muscle tissue gives skeletal muscles the ability to contract. Muscle is formed during ...
In an isotonic contraction, tension remains the same, whilst the muscle's length changes. Isotonic contractions differ from isokinetic contractions in that ...
Muscle contraction, the physiological condition of a muscle which generates tension (traction) at its origin and insertion · Contractility, the intrinsic ability ...
The physiological concept of muscle contraction is based on two variables: length and tension. In physiology, muscle shortening and muscle contraction are ...
Isolytic contraction is when a muscle contracts while external forces cause it to lengthen. For example, during a controlled lowering of the weight in a ...
Skeletal muscle is one of the three types of vertebrate muscle tissue, the other being cardiac muscle and smooth muscle. They are part of the voluntary ...
A tetanic contraction is a sustained muscle contraction evoked when the motor nerve that innervates a skeletal muscle emits action potentials at a very high ...
For voluntary muscles, contraction occurs as a result of conscious effort originating in the brain. The brain sends signals, in the form of action potentials, ...
