CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or false:muscle cells have exactly one nucleus per cell
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Skeletal muscle cells are long, cylindrical, and striated. They are multi-nucleated meaning that they have more than one nucleus. This is because they are formed from the fusion of embryonic myoblasts. Each nucleus regulates the metabolic requirements of the sarcoplasm around it.

Detailed explanation-2: -Muscle cells are one of the largest cell types, which are formed by fusion of mononucleated myoblasts and contain up to several tens (invertebrates) to several hundred (vertebrates) nuclei. Myonuclei are typically positioned at the cell’s periphery, and are distributed to maximize internuclear distance.

Detailed explanation-3: -Smooth muscle has no striations, is not under voluntary control, has only one nucleus per cell, is tapered at both ends, and is called involuntary muscle.

Detailed explanation-4: -The muscle cells attached to your skeleton and that help you move your body have multiple nuclei. Skeletal muscle is composed of long, fiber-like cells, which fuse together as they’re made. This means that each muscle cell has more than one nucleus because it is really made of several combined cells.

Detailed explanation-5: -Muscles are organs composed mainly of muscle cells, which are also called muscle fibers. Each muscle fiber is a very long, thin cell that can do something no other cell can do.
