T-Tubule - Invaginations of thesarcolemma penetrating deep into theinterior of the muscle cell. Synaptic Cleft - the space between the axon terminal and the motor end plate. Axon Terminal - the swollen distal end of themotor neuron axon

T-Tubule - Invaginations of the sarcolemma penetrating deep into the interior of the muscle cell.

Synaptic Cleft - the space between the axon terminal and the motor end plate.

Axon Terminal - the swollen distal end of the motor neuron axon.

Sarcolemma - the muscle cell membrane.

Synaptic Vesicles - structures within the axon terminal that contain the neurotransmitter acetylcholine (ACh).

Terminal Cisternae & Sarcoplasmic Reticulum (SR) - structures within skeletal muscle cells that serve as reservoirs of calcium ions.

Motor End Plate - a folded region of the sarcolemma at the neuromuscular junction.
