calcium increases the action potential transmitted along the scarcolemma
What else can I help you with?
What are contract muscles?
Smooth Muscle contractions are regulated by calcium ions. The smooth muscle differs from skeletal muscle in that its contracts from all sides.
What is the ion called that triggers muscle contractions?
There are several, but a calcium ion is one that is used in skeletal muscle contraction.
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
If a drug caused a sudden release of large amounts of calcium in skeletal muscle from which structure would the calcium come?
The calcium would come from the sarcoplasmic reticulum, which is a specialized structure found within skeletal muscle cells responsible for storing and releasing calcium ions for muscle contraction. A sudden release of large amounts of calcium from the sarcoplasmic reticulum can lead to uncontrolled muscle contractions and potentially muscle damage.
What neurotransmitter stimulates skeletal muscle contractions?
Acetylcholine
What are the three types of contractions of skeletal muscle?
isotonic concentric eccentric isometric
What are smooth muscle contractions?
Spindle shaped by faireena singh
Muscle contracts to move?
the muscles and the bone work together and attached
Can skeletal muscle be tetanised?
Yes, because of the short refractory period of skeletal muscle (compared to cardiac muscle), skeletal muscle can be restimulated before the muscle is completely relaxed. If repeated enough times, the contractions fuse together i.e. they become tetanised.
What muscle skeletal muscles do to move?
Skeletal muscles rely on contractions to move the bone they are attached to so it is contract and relax
Can A deficiency of calcium in the body can result in involuntary muscle contractions?
Yes it can
The structure storing calcium in the skeletal muscle fibers at rest is the?
The structure responsible for storing calcium in skeletal muscle fibers at rest is the sarcoplasmic reticulum. This organelle regulates the release of calcium ions during muscle contraction to trigger the muscle fiber to contract.
