Question

What are the different levels of organization of a muscle down to myofilaments

Answer 1

Answer:the different levels of organisation of muscles down to myofilaments includes: molecular level and microscopic levels

Step-by-step explanation:

The molecular level consist of actin and myosin( which forms the contractile units of the skeletal muscle). The actin and myosin filaments slide past each other to cause the shortening of a muscle fibre.

The microscopic level consist of sarcomere and myofibril. Sarcomere is the fundamental unit of muscle while the myofibrils consist of the myofilaments ( thick and thin filaments) which are organised into parallel units.

Answer 2

Molecular, Microscopic, Cell, Tissue and Organ levels

Step-by-step explanation:

The natural strength production needed for skeletal muscle to function occurs at the molecular level. You can develop a better knowledge of the properties of cells and tissues by simply studying the molecular systems common to the cells in question. The different muscular level down to myofilaments are:

• Molecular level — actin and myosin
• Microscopic level — sarcomere and myofibrils
• Cell level — myoblasts and myofibers
• Tissue level — neuromuscular intersections and fascicles
• Organ level — The key skeletal muscles of the body
