Describe the size, shape, & arrangement of cells for the Skeletal Muscles, Smooth Muscles, and Cardiac Muscles.

Respuesta :

gvcci
Skeletal muscle shapeSingle, very long cylindrical, multinucleated cells with obvious striations (nucleus at periphery); lots of mitochondria
Smooth muscle shapeSingle, spindle shaped cells (thick in the middle and tapered at the end), uninucleated (in the center); little mitochondria; dense bodies
Cardiac muscle shapeBranching chains of cells, uni or bi nucleated; striations; nucleus in center; lots of mitochondria; intercalated discs - 2 parts: Gap junctions and desmosomes

The skeletal muscles are cylindrical in shape, have multinucleated, and striated, and are under voluntary control. The size of these muscles may range from 2-3 cm. long and 100 micrometers in diameter. They are highly elongated in shape.

What is the size, shape, & arrangement of cells for the smooth muscles?

Smooth muscles are spindle-shaped cells that contain a single central nucleus. The size of these muscle cells may range from 10-600 micrometers in length.

They are the smallest type of muscle cells. Such types of muscle cells lack striations and are referred to as involuntary muscles.

Cardiac muscle cells are short, narrow, and significantly rectangular in shape. The size of these muscle cells is approximately 0.02mm wide and 0.1mm in length.

Such types of cells contain many sarcomeres that furnish the needed energy for the process of contraction.

Therefore, it is well described above.
