The sarcolemma is the thin, transparent cell membrane of a striated muscle cell, consisting of a plasma membrane and an outer coat.  The motor endplate is a specific part of the sarcolemma that contains acetylcholine (ACH) receptors and helps form the neuromuscular junction (the region of the muscle cell where a motor neuron stimulates the cell to contract).
