Neuromuscular Junction

Front

What happens once calcium is pumped into the axon terminal?

Back

ACh is released into the synaptic cleft.

Front

What is the point at which the nerve cell reaches the sarcolemma of the muscle fiber?

Back

Neuromuscular Junction (NMJ)

Front

What is the specific neurotransmitter that stimulates the movement of skeletal muscles?

Back

Acetylcholine (ACh)

Front

What is the gap between the nerve cell and sarcolemma called?

Back

Synaptic cleft

Front

What is defined as one neuron and all the skeletal muscle cells it stimulates?

Back

Motor unit

Front

What is the role of Acetylcholine (ACh) in muscle contraction?

Back

ACh binds to receptors on the sarcolemma, triggering muscle contraction.

Front

What is the function of the synaptic cleft?

Back

It is the space where neurotransmitters are released and bind to receptors.

Front

What occurs at the neuromuscular junction?

Back

The transmission of signals from the nerve to the muscle fiber.

Front

What is the role of calcium ions in muscle contraction?

Back

Calcium ions facilitate the release of ACh and initiate muscle contraction.

Front

What is a motor unit composed of?

Back

A motor neuron and the muscle fibers it innervates.
