A Muscle Twitch is a single contraction of skeletal muscle. The three distinct phases are latent, contraction, and relaxation.
Latent Phase: Is the interval from the stimulus application until the muscle begins to contract (shorten). Note that there is no traced activity during this phase, but there are some electrical and chemical changes taking place during this phase.
Contraction Phase: This phase is when the muscle fibers shorten, the tracings will show during this phase (a) peak(s).
Relaxation Phase: This phase is represented by the downward curve in your tracings, this is when the muscle is going back to its original state of relaxation and the muscle will once again lengthen

What are the three stages of a cell cycle in the eukaryotic cell?

Which pump is responsible for muscle contraction through depolarization of muscle cell membrane?
Ca2+
What does stretching a myocardial cell cause the cell to do?
Stretching a myocardial cell allows more Ca+2 into the cell and increases the force of contraction (the longer the muscle fiber when it begins to contract, the greater the force of contraction).
What are the three stages of the cell cycle in a eurkaryotic cell?
Interphase,Mitosis,Cytokinesis
What is a scaffolding of protein fibers that help a cell keep its shape and assist cell division and cell movement?
The cytoskeleton helps a cell keep its shape. The internal movement of organelles, as well as cell locomotion and muscle fiber contraction couldn't take place without it.

What are the 4 stages of a muscle cell?
Tonus (relaxation), Excitation (neural stimulation, Clonus (contraction), Tetanus (prolonged contraction), return to Tonus (relaxation) Or Excitation, Excitation-Contraction Coupling, Contraction, Relaxation
Describe the events of muscle cell contraction?
6 steps in a muscle contraction
What are three characteristics of muscle you can observe under microscope?
Isometric,Isotonic and Twitch-these are the three characeteristics of muscle contraction.

Which pump is responsible for muscle contraction through depolarization of muscle cell membrane?
Ca2+
Which of cell type is specialized for contraction and generation of force?
The three types of muscle cells (cardiac, smooth and skeletal) fit this description.
What organelle would be most common in a muscle cell?
Mitochondria - to produce the ATP needed for muscle contraction
What is the muscular structure?
The myofibril is the basic muscle cell, within which is the sarcomere, the basic unit of muscle contraction.
What is the process that takes place in a muscle cell to produce energy for it to work?
Contraction
The final step involved in skeletal muscle contraction is?
The muscle cell relaxes and returns passively to its resting length
What does stretching a myocardial cell cause the cell to do?
Stretching a myocardial cell allows more Ca+2 into the cell and increases the force of contraction (the longer the muscle fiber when it begins to contract, the greater the force of contraction).
Why can the contraction of the muscle tissue cause your arm to bend but the contraction of a single muscle cell would have no effect?
It doesn't have "no effect" ... it's just too feeble to be noticed.
