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.

1 is C - see first attachment. Genotypes with Y's represent males, and big R represents red eyes, while little r represents white eyes. For example XRxr is a heterozygous (red-eyed) female, and XrYr is a homozygous white-eyed male.

2 is B because the absence of functional proteins and some ribosomes due to the mRNA strand is not as detrimental as the loss of the entire cell.

3 is B. (The insertion of 3 base pairs into a genetic sequence is the length of a single codon, meaning that only one amino acid in the entire polypeptide was added)
