The effect of calcium ions on neurotransmitter release at synapses include:
- A. vesicular fusion
- B. tonic depolarization of the presynaptic neurone
- C. post-tetanic potentiation
- D. all above
Correct Answer: D
Rationale: Calcium ions trigger vesicular fusion, contribute to post-tetanic potentiation, and can cause tonic depolarization in the presynaptic neuron. These effects are essential for synaptic plasticity and neurotransmission.

Parkinsonism includes combination of the following:
- A. tremor, bradykinesia & muscles rigidity
- B. paresis, anesthesia & muscles spasticity
- C. chorea & muscles hypotonia
- D. tremor, ataxia & muscles hypotonia
Correct Answer: A
Rationale: Tremor, bradykinesia, and muscle rigidity are the correct answers because these are the cardinal features of Parkinsonism. Bradykinesia refers to slowness of movement, rigidity refers to increased muscle tone, and tremor is often present at rest. These symptoms result from the degeneration of dopaminergic neurons in the substantia nigra.
One of the three basic parts of a neuron is the ________.
- A. axon
- B. myelin
- C. pons
- D. dura mater
Correct Answer: A
Rationale: A neuron consists of three basic parts: the cell body, dendrites, and axon. The axon is a long, slender projection that transmits nerve impulses away from the cell body to other neurons or target cells. Myelin is a protective sheath around some axons, the pons is a part of the brainstem, and the dura mater is a meningeal layer. Therefore, axon is the correct answer as it is one of the fundamental components of a neuron.
