MUSCLE PHYSIOLOGY

Detailed explanation-1: -Cell level-myoblasts and myofibers. Tissue level-neuromuscular junctions and fascicles. Organ level-major skeletal muscles of the body.

Detailed explanation-2: -Muscle cells, commonly known as myocytes, are the cells that make up muscle tissue. There are 3 types of muscle cells in the human body; cardiac, skeletal, and smooth. Cardiac and skeletal myocytes are sometimes referred to as muscle fibers due to their long and fibrous shape.

Detailed explanation-3: -Skeletal muscle fibers are organized into groups called fascicles. Blood vessels and nerves enter the connective tissue and branch in the cell. Muscles attach to bones directly or through tendons or aponeuroses.
