Ca 2+  ions in nerve action 5 A nerve impulse is transmitted through the use of calcium ions and neurotransmitters. The nerve impulse triggers the opening of calcium channels allowing Ca 2+ ions to migrate into the cell. The presence of Ca 2+ ions triggers release of neurotransmitters (acetylcholine ACh) into the synapse. The neurotransmitters collect on the other side of the gap and trigger a contraction.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
