Question

What is the shape of the muscle cells?
A. Spindle
B. Spherical
C. Long and branched
D. None of the above

Answer 1

Muscles are the organs of the muscular system that are mostly connected to bones by the tendon. The cells of muscles in the skeletal muscles are longer than in the other types of muscular tissue, and are usually called as muscle fibers. These skeletal muscle cells are striated (striped appearance) which is because of the arrangement of sarcomeres. The sarcomere is the contracting unit of the skeletal muscle.

Complete answer:
Skeletal muscles are voluntary muscles which means they are under the control of our nervous system, they work on our will. The cardiac muscle and smooth muscle are both involuntary in nature because they are not under the control of our will. The cardiac muscles are striated.
A skeletal muscle is composed of various fascicles which are bundles of muscle fibers. Every individual fiber, and each muscle is encircled by a sort of connective tissue layer of belt. Muscle filaments are shaped from the combination of formative myoblasts in an interaction known as myogenesis coming about in long multinucleated cells. In these cells the cores named myonuclei are situated within the cell layer. Muscle strands likewise have different mitochondria to address energy issues. Muscle fibers are actually composed of myofibrils.
The muscle cells are spindle shaped. Some blood cells are spherical, neurons on the other hand are long and branched.

So, the correct answer is option A which is spindle shaped.

Note:
The myofibrils are made out of actin and myosin fibers called myofilaments, rehashed in units called sarcomeres, which are the essential practical, contractile units of the muscle fiber important for muscle constriction. Muscles are prevalently controlled by the oxidation of fats and starches, yet anaerobic compound responses are likewise utilized, especially by quick jerk filaments.
