during what phase of a muscle twitch chemical changes such as the release of calicum are according intracelluary as rthe muscles
SOVA2 [1]

<u>During </u><u>latent </u><u>phase of a muscle twitch chemical changes such as the release of calicum are according intracelluary as rthe muscles prepare for contractrion.</u>

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 sarcoplasmic reticulum 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.

Desmosomes form channels that allow each cardiocyte to electrically stimulate its neighbors. True False
dimulka [17.4K]

Answer:

False

Explanation:

The most specific feature of cardiac muscles is the presence of intercalated discs. Intercalated disc connects the ends of cardiac muscle fibers to one another. The discs have desmosomes and gap junctions. The function of desmosomes is to hold the cardiac fibers together. The gap junctions of cardiac fibers allow muscle action potentials to spread from one cardiac muscle fiber to another. These gap junctions have tubular connexons that form channels and connect the cytosol of adjacent cardiocytes to allow the flow of ions and spread of action potential from one cell to another.
