What else can I help you with?
Specifically what is responsible for the banding pattern in skeletal muscle cells?
Prosomes form sarcomere-like banding patterns in skeletal, cardiac, and smooth muscle cells.Actin and Myosin proteins
When a muscle contracts how does its form change?
A muscle that contracts shortens whereas a muscle that relaxes lengthens.
What is a smooth muscle that contracts or relaxes to change the volume of the chest?
The Diaphragm.
What is the cause of the banding pattern visible in striated muscle?
The banding pattern visible in striated muscle is due to the arrangement of thick and thin filaments within muscle fibers. The alternating dark A bands (containing thick filaments) and light I bands (containing thin filaments) create the striated appearance. This banding pattern is essential for the function of muscle contraction.
What does a muscle become when it contracts?
A muscle becomes shorter when it contracts.
What happens to the length of a muscle when it contracts?
When a muscle contracts, it shortens in length.
When a muscle contracts, it pulls with what force?
When a muscle contracts, it pulls with a force generated by the muscle fibers contracting and shortening.
When a muscle contracts but does not change length what type ofpools networks of?
When a muscle contracts but does not change length, it is undergoing isometric contraction. During this type of contraction, the muscle generates tension without any visible movement or change in the muscle's length. This is commonly observed when holding a weight in a fixed position or pushing against an immovable object. Isometric contractions are important for stabilizing joints and maintaining posture.
When one muscle contracts what happens to the opposing muscle?
When one muscle in a pair contracts the other expands.
Which muscles contracts when the leg is extended at the knee?
The muscle that contracts when the leg is extended at the knee is call the gastrocnemius muscle
When a muscle contracts it?
shortens
When the muscle contracts it is?
Flexion
