Question

Striated muscle fibers possess
A. Longitudinal strips
B. Oblique strips
C. Transverse strips
D. No strips

Answer 1

Striated muscle fibers present in muscles. These help in the contraction and relaxation. Bands are appearing in muscles. The arrangement of light and dark bands in these muscles is transverse. Sarcomere plays important role in the contraction of muscles.

Complete answer:
Striated muscles appear as transverse strips when viewed under the microscope. They show alternative transverse light and dark bands. Most striated muscles are attached to bones by tendons. They are also called skeletal muscles. It is a muscle tissue that has sarcomeres. The presence of sarcomeres present as a series of bands visible along the muscle fibers. Striated muscle can be of two types of cardiac muscle and skeletal muscle. T-tubules present in striated muscle tissue enables the release of calcium ions from the sarcoplasmic reticulum. They are classified as slow-oxidative or fast-oxidative based on their contractile and metabolic phenotypes. Cardiac muscles are present in the heart. These cells are connected with each other by intercalated disks, which contain gap junctions and desmosomes. The main function of striated muscles is to create force and contract. It consists of bands termed as A, M, I, and Z lines. They have thick filaments of myosin and proteins that bind myosin
From the above information, we have found that striated muscle fibers possess transverse strips.

Hence, the correct answer is option (C).

Note: If the cardiac muscles are injured they cannot regenerate. During development, mammals can complete a small amount of cardiac regeneration. Regeneration can occur in skeletal muscles. This can be done with help of satellite cells which are dominant in all healthy skeletal muscles. Micro RNAs regulate various programs controlling cell differentiation and morphogenesis.
