The structure storing calcium in the skeletal muscle fibers at rest is the?
sarcoplasmic reticulum
Is calcium a fiber?
No. Calcium does have a major role in muscle fibers when your muscles contract, but it is not the actual fiber.
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.
What type of muscle fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
What is the function of the muscle fibers?
muscle fibers contract the muscles when stimulated.
Does glycerinated skeletal muscle fibers need ATP in order to contract?
true
Does glycerinated skeletal muscle fibers nee ATP in order to contract?
no, they need ATP
The structure storing calcium in the skeletal muscle fibers at rest is the?
sarcoplasmic reticulum
Is calcium a fiber?
No. Calcium does have a major role in muscle fibers when your muscles contract, but it is not the actual fiber.
Which fibers carry action potential to cause skeletal muscles to contract?
Alpha motor neurons
Skeletal muscle fibers differ from typical cells in that these muscle fibers?
Skeletal muscle fibers differ from typical cells in that these muscle fibers have many nuclei. The skeletal muscle store calcium ions in the sarcoplasmic reticulum.
When do you see glycerinated muscle shorten?
Glycerinated muscle can shorten when ATP is present, allowing myosin cross-bridges to form and generate force. However, once ATP is depleted or unavailable, glycerinated muscle cannot shorten as it lacks the energy to power the cross-bridge cycling.
At what junction do nerves contact skeletal muscle fibers?
Motor neurons meet the muscle cells at neuromuscular junctions. Neurotransmitters are passed from the nerve across a synaptic cleft to the muscle to make it contract. Any damage to this nerve will mean that those cells will not contract (move).
How are smooth muscle cells similar to skeletal fibers?
Smooth muscle cells are similar to skeletal muscle cells due to the actin-tropomyosin interactions. These interactions "tell" the muscle when to contract.
What is a group of skeletal muscle fibers?
A skeletal muscle
Bone that consists of hardened fibers interspersed with many spaces?
Spongy bone provides lightweight support. Consists of hardened fibers interspersed with many spaces. Skeletal system made of calcium hardened collagen fibers that make it strong but flexible.
Is skeletal muscle made of muscle fibers?
Basically, yes. All muscle (skeletal, cardiac and smooth) are made of muscle fibers.
