GENERAL HISTOLOGY

Detailed explanation-1: -Each muscle fibre is lined by the plasma membrane called sarcolemma enclosing the sarcoplasm . Muscle fibre is a syncitium as the sarcoplasm contains many nuclei. The endoplasmic reticulum, i.e., sarcoplasmic reticulum of the muscle fibres is the store house of calcium ions.

Detailed explanation-2: -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. It consists of a lipid bilayer and a thin outer coat of polysaccharide material (glycocalyx) that contacts the basement membrane.

Detailed explanation-3: -This is muscle cell. The lining over muscle fibre is called sarcolemma. The protoplasm in the muscle fibre is called sarcoplasm. The endoplasmic reticulum in muscle fibre is called sarcoplasmic reticulum.

Detailed explanation-4: -Sarcolemma is the name of the cell membrane that encloses each muscle cell, specifically muscle cells ("muscle cell” = “muscle fibre")
