GENERAL HISTOLOGY

Detailed explanation-1: -The sarcolemma (sarco (from sarx) from Greek; flesh, and lemma from Greek; sheath) also called the myolemma, is the cell membrane surrounding a skeletal muscle fiber or a cardiomyocyte.

Detailed explanation-2: -The sarcolemma is a specialized membrane which surrounds striated muscle fiber cells.

Detailed explanation-3: -A sarcomere (Greek sarx “flesh", meros “part") is the smallest functional unit of striated muscle tissue. It is the repeating unit between two Z-lines. Skeletal muscles are composed of tubular muscle cells (called muscle fibers or myofibers) which are formed during embryonic myogenesis.
