(c) Z-band (d) cross bridges

Answer 1

Answer:

the correct answer is option (c)

Answer 2

Composition of muscle fibers:

• Option “A” is correct i.e. Myofibrils.

• Muscle fibers are composed of numerous fine fibrils called myofibrils.

• A myofibril (also recognized as a muscle fibril) is a simple rod-like unit of a muscle cell. Muscles are poised of tubular cells named myocytes, known as muscle fibers in striated muscle, and these cells, in turn, cover many chains of myofibrils.
