Why do skeletal muscle cells have more than one nucleus?
Skeletal muscles are straited, multinucleate cells. Stimulated by voluntary/ somatic nervous system. Skeletal muscles cause forceful, strong contractionsCardiac 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)
Why do some cells have more than one nucleus?
Multinucleated cells, such as muscle cells and certain fungi, have multiple nuclei to support their large size and high metabolic demands. Having multiple nuclei allows for more efficient control of gene expression and protein synthesis throughout the cell. In the case of muscle cells, multiple nuclei help coordinate muscle contraction and repair.
Does bears cells have a nucleus?
Virtually all eukaryotic (meaning all plants, animals, funghi, etc) cells have nuclei. The only exception of which I can think are erythrocytes (red blood cells) which lose their nuclei as they mature in mammals.
Which organisms have cells without nuclei?
Organisms that have cells without nuclei are called prokaryotes. This includes bacteria and archaea. Prokaryotic cells do not have a defined nucleus but instead have a nucleoid region where the genetic material is located.
Do bacterial cells contain nuclei?
No, bacterial cells do not contain nuclei. Bacterial cells are prokaryotic, which means they do not have a membrane-bound nucleus. Instead, their genetic material is present in a circular chromosome located in the nucleoid region of the cell.
What kind of cell in the human body do you think would have more mitochondria cell or a skin cell?
They are in active cells. Some like muscle and cardiac cells
Is a nuclear pore prokaryotic?
A nuclear pore is not a cell. It is not even an organelle, only a characteristic/part of the nucleus. I think you mean are cells with nuclei prokaryotic. No, possessing nuclei is a characteristic of eukaryotic cells. If you need more information, see the related link.
What wind of cell in the human body do you think would have more mitochondria?
Cells which are very active.They need a lot of energy. Cardiac ,muscle cells are some examples
Skeletal muscle fibers differ from typical cells in that these muscle fibers?
contain multiple nuclei and are elongated, allowing for contraction and relaxation to generate movement in the body. They also have a striated appearance due to the arrangement of myofilaments within the cell, which aids in the sliding filament mechanism of muscle contraction.
Why do you think cardiac muscle is involuntary?
Cardiac muscle will beat on its' own. You don't have to think about.
What tissue is your heart composed of?
Cardiac Muscle tissue =)
What is an example of cardiac?
I think that the best example of a cardiac muscle would be...the heart, seeing as the root for cardiac means heart in Latin.
