Interactions between actin and myosin filaments of the sarcomere are responsible for muscle contractions. The I bands contain only thin (actin) filaments, whereas the A bands contain thick (myosin) filaments.

What is the sound following the flash of lighting?
The sound following the flash of lightning is thunder. Thunder is caused by the rapid expansion and contraction of air surrounding the lightning bolt, creating a sonic shockwave that we hear as a loud rumbling noise.
What are the points on a map connected by?
Points on a map are connected by lines, which are known as routes or paths. These lines represent the physical or conceptual connections between the points, such as roads, rivers, or airline routes. By following these lines, travelers can navigate from one point to another on the map.
How many watts does a whole house generator use?
The size of a generator is based on what the connected load will be. Add up all of the connected wattages that will be connected to the generator at one time and add ten percent, this will be the size of the generator you will need. Some equipment does not show the wattage on its nameplate. To find the wattage use the following formula Watts = Amps x Volts.
What is repolarization of the sarcolemma?
Repolarization of the sarcolemma refers to the process of restoring the electrical charge across the muscle cell membrane following depolarization. It involves the movement of potassium ions out of the cell, returning the membrane potential to its resting state. This repolarization phase is critical for the muscle cell to prepare for its next contraction.
What does a smooth endoplasmic reticulum do in a plant cell do?
The smooth endoplasmic reticulum is a vast network of membrane-bound vesicles and tubules. It does the following: 1. lipid and steroid hormone synthesis 2. breakdown of lipid-soluble toxins in liver cells 3. control of calcium release in muscle cell contraction
Which of the following provide shape to the cell?
microfilaments intermediate filaments
Excitation-contracton coupling requires which of the following substances?
Excitation-contraction coupling requires calcium ions to trigger the release of calcium from the sarcoplasmic reticulum in muscle cells, leading to muscle contraction. It also involves the action of proteins like troponin and tropomyosin to regulate the interaction between actin and myosin filaments.

What is the formula for Lorentz contraction?
Lorentz contraction, or length contraction, coresponds to following formula: l = l0 * sqrt(1-V2/c2)
What is the name of the theory muscle contraction illustrated in the transparency?
In short, the basic contraction unit of the muscle is the sarcomere. Many sarcomeres work serially and in parallel to acheive the full contraction ability of the muscle. The sarcomere is made up of many filaments of Actin and Myosin, two types of protein based filaments that reach out towards each other from opposing sides of the sarcomere. When the muscle is at rest, the Actin and myosin filaments overlap each other the least. In order for the muscle to contract, the filaments from the opposing sides slide over each other thus pulling both walls of the sarcomere towards each other, with them. When the muscle is fully contacted, the filaments overlap each other the most. The sliding motion is activated by calcium that floods the sarcomeres (at the end of a process that is triggered by a command from a motor nerve). The calcium reveals sites on the Actin filaments at which molecular 'whips' extending from the Myosin filaments, can throw themselves, attach, pull, and leave, using the muscle's energy reserves in the process. Each molecular whip works at its own time (much like cylinders in an internal combustion engine), so that in any given time, contact between the filaments is being made by some of the whips.
Which of the following transformations preserves the lengths of the sides of the figure?
contraction
What is an aftermovement?
An aftermovement is the movement of a limb following the contraction of a muscle.
Which of the following scale factors would produce a contraction under a dilation of the original image?
The answer is 0.5
Which of the following best describes the events of excitation in excitation-contraction coupling?
Propagation of the action potential along the sarcolemma
Which of the following transformation will always produce a congruent figure a rotation b contraction c dilation d expansion?
A. Rotation
