Definitions:

Actin Myofilaments

Thin filaments within muscle cells that, along with myosin, contribute to muscle contraction and relaxation.

Threshold Level

A threshold level refers to the minimum intensity that stimulates a perceptible response in a physical, biological, or psychological system.

Neuromuscular Junctions

Specialized synaptic contacts between motor neurons and skeletal muscle fibers that facilitate muscle contraction.

Presynaptic Terminal

The terminal segment of an axon responsible for discharging neurotransmitters into the synaptic gap, thereby facilitating communication with an adjacent neuron.
