Acetylcholinesterase
Acetylcholinesterase is the enzyme that breaks down acetylcholine at the neuromuscular junction.
Actin
Actin: Provides binding sites for myosin.
Excitation-contraction coupling
Excitation-contraction coupling is the process linking a muscle action potential to calcium release and contraction.
Myosin
Myosin: Forms cross-bridges and performs the power stroke.
Neuromuscular junction
The neuromuscular junction (NMJ) is the synapse (connection) between a motor neuron and a skeletal muscle fiber.
Rate coding
Rate coding refers to the frequency at which motor units are stimulated to contract.
Sliding filament theory
The sliding filament theory describes how actin and myosin filaments within the sarcomere interact to produce muscle contraction.
