Skeletal muscles are straited, multinucleate cells. Stimulated by voluntary/ somatic nervous system. Skeletal muscles cause forceful, strong contractions
Cardiac muscles are also straited, yet they have 1-2 nuclei per cell. Stimulated by involuntary/autonomic nervous system. Cardiac muscles cause strong, forceful interactions (think of the heart beating, & its ventricles pumping out the blood)
Smooth muscles are nonstraited, have one nucleus per cell. Stimulated by the involuntary/autonomic nervous system. They have smooth, continuous contractions (think of the digestive system)
that is not true. the heart is made from many cells all of which theoretically contain a nucleus. red blodd cells are the only type of cells which exist in large numbers in the body but do not have a nucleus
Cells are equipped with an appropriate amount of mitochondria to satisfy their energy demands. Cardiac cells, due to their frequent and constant work (the pumping of the heart), have high energy demands and therefore high levels of mitochondria.
Cardiac muscle cells only have one nucleus. Under a microscope, cardiac muscle cells appear to have more than one nucleus due to the resulting fusion of two or more uninuclear cells
More nuclei=more protein production capacity. Since skeletal muscles have high turnover of proteins, the extra nuclei help with this turnover.
They are the result of the fusion of precursor nucleated cells during their differentiation into skeletal muscle cells.
5. Yeup, that's it! Only five.
Some cells have more nuclei because they have more jobs to do than other cells. You can think of these cells like a major corporation, where in order to efficiently run, there needs to be more than one manager.
Eukaryotic cells are typically larger than prokaryotic cells because they are more complex. They have an enclosed nucleus and more jobs to fulfill.
Actually, Skeletal muscle in and of itself is a TYPE of muscle. There are three types of muscle.1.) Skeletal - the muscles that help us move around daily and are under voluntary control2.) Cardiac- the heart muscle basically3.) Smooth- these muscles are under involuntary nervous control. For example, the muscles in your digestive tract contract to move food downward. You don't have to think to initiate contractions do you? :)Skeletal Muscle can further more be broken down into fiber types I, II( IIa, IIb, IIx)type I muscles are slow twitch- highly resistant to fatigue. Type II are fast-twitch and have a low resistance to fatigue.
Muscle cells are very active relatively to the skin cell. So it has more mitochondria
eukaryotic cells have a nucleus that holds their DNA. Prokaryotic cells have no nucleus and their DNA floats around the cell. Eukaryotic cells generally have a lot more DNA than prokaryotic cells because prokaryotic cells are a lot less complicated than their counterpart.
Skeletal muscles (the ones in arms, legs and other moving parts of the body) have large numbers of nuclei. They are formed during development by the fusion of many single nucleus myoblastcells . Other muscle cells, like the cardiac muscle cells in the heart or smooth cells in the gut, do not fuse and have only one nucleus. For more information see "Molecular Biology of the Cell" published by Garland Press.
Skeletal muscle cells have more than one nucleus.
Both are very active.But skeletal muscles have more.
Skeletal Muscle
Most of eukariyotic cells have only one nucleus.But some cells have more than one nucleus. Eg:-Skeletal muscle cells.Some cells do not have a nucleus.Eg:-Erythrocytes,Seive tube elements

skin cells are specialized which means they are quickly to be shed and replace while muscle cells are very different because they aren't really that easy to replace
true
Striated muscle includes cardiac muscle and skeletal muscle. Cardiac muscle is found only in the heart. Skeletal muscle is between bones and is voluntarily controlled. Examples of skeletal muscle are the sternoclydomastoid, biceps, obicularis oris, rectus femoris, etc.
The tissue that has more than one nucleus and is voluntary is the skeletal muscle. The tissues that are small, spindle shaped, and found in the walls of hollow organs are smooth muscles.
One key difference between cardiac and skeletal muscles is that skeletal muscles are controlled by the nervous system, while cardiac muscles move involuntarily. In addition, cardiac muscles are only found in the heart, while skeletal muscles are found throughout the entire body.
