Correct Answer: C

Rationale: Dendrites are the part of a neuron responsible for receiving information from other neurons. They are branched structures that extend from the cell body and contain receptors for neurotransmitters. When neurotransmitters bind to these receptors, they generate electrical signals that travel toward the cell body, initiating communication between neurons. Dendrites play a crucial role in integrating incoming signals and determining whether the neuron will fire an action potential.

Correct Answer: A

Rationale: Curare is an antagonist for the neurotransmitter acetylcholine, meaning it blocks acetylcholine receptors at the neuromuscular junction. This prevents acetylcholine from binding to its receptors and initiating muscle contraction, leading to paralysis. Curare has been used historically as a poison and in medical procedures to induce muscle relaxation. Its action highlights the importance of acetylcholine in muscle function and the effects of receptor blockade.

Correct Answer: C

Rationale: Neuroplasticity refers to the brain's ability to reorganize itself by forming new neural connections in response to learning, experience, or injury. This adaptability allows the brain to compensate for damage and recover lost functions. Neuroplasticity is the basis for learning and memory and plays a crucial role in rehabilitation after brain injury. It highlights the brain's remarkable capacity for change and adaptation.
