Students have asked these similar questions
Skeletal muscle cells cannot divide. How does skeletal muscle repair itself when injured?
1) capZ encourages the elongation of actin filaments (true or false)
2)microtubules are tissue specific (true or false )
3) microtubule-associated proteins stabilize microtubules along their length (true or false)
During a histological examination of muscle tissue you see a cell that is striated. You determine that it is a cardiac myocyte because it
Possesses multiple nuclei per cell
O Contains neuromuscular junctions
Has intercalated disks with one nucleus per cell
Is spindle shaped with a single nucleus
Lacks intercalated disks

- Cardiac muscle differs from smooth and skeletal muscle because.... It is composed of long and cylindrical fibers, each of which has multiple nuclei. It is composed of a branching network of fibers and is only found in vertebrates. It typically contracts more rapidly than skeletal or smooth muscle. It is composed of long and cylindrical fibers with one nucleus per cell. It is composed of a branching network protected by chitin.arrow_forwardTumors associated with breast cancer usually arise from either epithelial cells or fibroblasts. Because optimal treatment differs depending on the cellular origin of the tumor, it’s important for doctors to determine which cell type is present in a tumor. Unfortunately, the distinctive morphology of epithelial cells is lost when they become cancerous, so this determination cannot be made based on cell shape alone.
