### Educational Material on Neurophysiology#### Multiple Choice Question: Understanding Neuron Function**More than one answer may apply.****When voltage-gated sodium channels of a resting neuron open:**1. ☐ Na enters the neuron2. ☐ Cl channels open3. ☐ the neuron depolarizes4. ☐ Na leaves the neuron---This multiple-choice question focuses on the physiological processes that occur when voltage-gated sodium channels in a resting neuron open. Understanding this concept is pivotal for learning about action potentials and neural signaling.#### Explanation:1. **Na enters the neuron**: This option is correct. When voltage-gated sodium (Na) channels open, sodium ions rush into the neuron due to the electrochemical gradient.2. **Cl channels open**: This option is incorrect. The opening of voltage-gated sodium channels does not directly cause chloride (Cl) channels to open.3. **The neuron depolarizes**: This option is also correct. The influx of sodium ions decreases the membrane potential, leading to depolarization of the neuron.4. **Na leaves the neuron**: This option is incorrect. Sodium ions do not leave the neuron when voltage-gated sodium channels open; instead, they enter the neuron.

(Multiple answers possibly) the absolute refractory period prevents this from happening Sodium voltage gated ions in the area where the action potential just came from are fully activated or inactivated Sodium voltage gated ions bind to the Na+ ions, preventing them from diffusing backwards Na+ only diffuses forward in the axon 2.
