Question
**Title: Understanding Action Potentials** **Question:** "Action potentials are produced by voltage-gated channels." **Options:** - True ⬜ - False ⬜ **Explanation:** This concept relates to the mechanism by which neurons communicate through electrical signals. Action potentials are critical for nerve impulse transmission and are indeed facilitated by voltage-gated ion channels. These channels open and close in response to changes in membrane potential, allowing ions such as sodium (Na+) and potassium (K+) to flow across the neuronal membrane, generating an action potential. Understanding this process is fundamental in neurobiology and helps explain how the nervous system functions efficiently. **Interactive Feature:** This section can be used as a quiz item to test students' comprehension of the role of voltage-gated channels in neuronal signaling.
