What qualities do cardiac and skeletal muscles share?
Cardiac and skeletal muscles are both striated muscles that contract in response to nerve impulses. They contain sarcomeres as their basic contractile unit and rely on the presence of calcium ions for muscle contraction. Additionally, both types of muscles are composed of muscle fibers that vary in size and length.
What level of muscle use the creatine-phosphate powers?
The level of muscle that creatine-phosphate powers is striated or skeletal muscles.
Most skeletal muscles contain?
muscle fiber
The liver can supply the skeletal muscles with energy in the form of free glucose but the skeletal muscles cannot supply the liver with energy in the form of free glucose?
No. Unlike skeletal muscles, the liver contains an enzyme known as glucose 6-phosphatase that can remove the phosphate groups and produce free glucose.
What muscles are the muscles that move bones?
These muscles are called "skeletal muscles".
What do skeletel muscles contain?
Skeletal muscles contain muscle fibers, which are long, cylindrical cells that are multinucleated and striated due to the organization of actin and myosin filaments. They also contain connective tissue, blood vessels, and nerves, which supply nutrients and facilitate movement. Additionally, skeletal muscles have specialized structures called tendons that attach them to bones, enabling voluntary movement of the skeletal system.
Does skeletal muscles move limbs and produce smiles?
Yes, skeletal muscles are responsible for the movement of limbs in the body. They contain muscle fibers that contract and relax, causing the bones they are attached to move. Skeletal muscles also play a role in producing smiles, as they assist in the movement of the muscles in the face that create facial expressions.
Where is calcium stored in a relaxed skeletal muscle?
yes calcium is stored in muscles as it is necessary for muscle contraction and muscle contraction is very sensitive to the amount of calcium
What part of the body does not contain muscles?
The nervous system, the endocrine system, and the skeletal system.
What are rodlike structures within skeletal muscles that contain filaments organized into sarcomeres?
myofilaments
Do cardiac muscle cells contain more mitochondria than skeletal muscle cells?
Both are very active.But skeletal muscles have more.
What muscles are muscles that move bones?
Skeletal muscles .
