GENERAL HISTOLOGY

Detailed explanation-1: -A sarcomere is the region from one Z line to the next Z line. Many sarcomeres are present in a myofibril, resulting in the striation pattern characteristic of skeletal muscle.

Detailed explanation-2: -Muscles are composed of long bundles of Myocytes (Muscle fibers). Myocytes contain thousands of myofibrils.

Detailed explanation-3: -Skeletal muscle cells and cardiac muscle cells both contain myofibrils and sarcomeres and form a striated muscle tissue.

Detailed explanation-4: -A myofibril is a long cylindrical organelle found in muscle cells formed by two transverse filament systems: the thick and thin filaments.
