Answer :
Motor end plate is the the indented region of the sarcolemma that participates in the neuromuscular junction.
The cell membrane enclosing a skeletal muscle fibre or a cardiomyocyte is known as the sarcolemma, sometimes known as the myolemma. It is made up of a lipid bilayer and a thin polysaccharide layer that touches the basement membrane on the outside. Numerous tiny collagen fibres and specific proteins, including laminin, can be found in the basement membrane region, which acts as a framework for the muscle fibre to adhere to. The actin skeleton inside the cell is coupled to the basement membrane and the cell's surface by transmembrane proteins in the plasma membrane. The surface layer of the sarcolemma merges with a tendon fibre at each end of the muscle fibre, and the tendon fibres then group together into bundles to produce the muscle tendons that attach to bones.
