Neuromuscular Junction Review

Front

What is the neurotransmitter stored in the axon terminal?

Back

Acetylcholine

Front

Which muscle characteristic allows the muscle to return to resting length after contraction?

Back

Extensibility

Front

What is the location where the motor neuron reaches the sarcolemma of the muscle fiber?

Back

Neuromuscular Junction

Front

What is the function of the neuromuscular junction?

Back

Controlling a skeletal muscle contraction

Front

What structure stores neurotransmitters?

Back

Synaptic vesicles

Front

What is the role of acetylcholine in muscle contraction?

Back

It binds to receptors on the muscle fiber, triggering contraction.

Front

What is the synaptic cleft?

Back

The gap between the axon terminal and the muscle fiber.

Front

What is the function of calcium ions (Ca²⁺) in muscle contraction?

Back

They facilitate the release of acetylcholine from synaptic vesicles.

Front

Define contractility in the context of muscle tissue.

Back

The ability of muscle fibers to shorten and generate force.

Front

What is excitability in muscle fibers?

Back

The ability to respond to stimuli and generate action potentials.
