Following neurotransmitter activation of chemically gated channels,

Question

Quizplus · Accepted Answer

When neurotransmitter activates chemically gated channels, sodium ions (Na+) flow into the cell, causing the inside of the membrane to become more positive, generating a local potential. This local potential may or may not be large enough to cause the cell to reach threshold and generate an action potential. The Na+ channels open for a brief time, generating a local current by allowing positively charged ions to enter the cell. Therefore, all of the above (A, B, C, and D) are correct.
