A contractile response of an unmarried muscle fiber to a single muscle impulse is known as a muscle twitch. A muscle twitch is the result of an unmarried muscle fiber contracting in response to a motor neuron-stimulating event. when multiple movement potentials are sent, it is known as wave summation.
Muscle contraction begins when the nervous system generates a sign. The single, impulse known as a movement ability, travels via a sort of nerve mobile referred to as a motor neuron. The neuromuscular junction is the cell of the area in which the motor neuron reaches a muscle mobile.
The electrochemical transmission of a single alongside a nerve fiber produces an excitatory or inhibitory response at a goal tissue, which includes a muscle or any other nerve. A "twitch" represents an unmarried muscle contraction in reaction to a single over-threshold stimulus. A sarcomere is the primary contractile unit of a myocyte (muscle fiber).
