Read each question carefully and answer to the best of your knowledge. Refer to the diagram provided for relevant questions.
Observe the diagram of the neuromuscular junction below to answer the following questions.
1. The specialized synapse between a motor neuron and a muscle fiber is called the .
2. The neurotransmitter released at the neuromuscular junction is .
3. The binding of the neurotransmitter to receptors on the muscle fiber causes a change in its , leading to muscle contraction.
4. Which of the following structures is NOT part of the neuromuscular junction?
Motor end plate
Synaptic cleft
Dendrite
Presynaptic terminal
5. What is the primary function of the neuromuscular junction?
To generate action potentials in neurons
To transmit nerve impulses to muscle fibers
To produce ATP for muscle contraction
To store calcium ions
6. Acetylcholinesterase is an enzyme that breaks down acetylcholine in the synaptic cleft.
True
False
7. The motor end plate is a part of the motor neuron.
True
False
8. Describe the sequence of events that occurs when an action potential reaches the presynaptic terminal of a neuromuscular junction, leading to muscle fiber depolarization.
9. Explain the role of calcium ions in the release of neurotransmitters at the neuromuscular junction.
