What are the phases of a twitch contraction?
A single contraction is called a twitch. A muscle twitch has a latent period, a contraction phase, and a relaxation phase.
A graded muscle response allows variation in muscle tension.
What is a latent period ?
The amount of time that passes between an action potential being generated in a muscle cell and the beginning of muscular contraction.
What is a muscle twitch?
The fundamental reaction of a motor unit to a single stimulus is a muscle twitch. Muscle Twitch in three different states .
Excitation of the muscle fiber takes place during the latent phase, and calcium ions are released from the sarcoplasmicreticulum into the cell's cytoplasm.
What happens during latent period of muscle twitch?
A single muscle twitch consists of three parts. the contraction phase, the relaxation phase, and the latent period, often known as the lag phase.
The action potential reaches the muscle, and the latent period is the brief (1-2 msec) interval before tension is seen in the muscle.
(VEE-nuh KAY-vuh) A large vein that carries blood to the heart from other areas of the body. The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest.
