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
What neurotransmitter stimulates skeletal muscle contractions?
Acetylcholine
What are smooth muscle contractions?
Spindle shaped by faireena singh
What are the three types of contractions of skeletal muscle?
isotonic concentric eccentric isometric
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
What is the purpose of the sodium-calcium exchanger in cardiac muscle?
Unlike skeletal muscles, cardiac muscles need extracellular calcium ions in order to perform contractions. The sodium-calcium exchanger is the protein that facilitates this transfer, trading calcium from outside the cardiac cell with sodium inside the cell.
Can A deficiency of calcium in the body can result in involuntary muscle contractions?
Yes it can
The somatic nervous system issues somatic motor commands that?
contractions of skeletal muscle
