Nervous System Pt1

8. single output channel, takes electrical signal and releases chemical neurotransmitters to next neuron
11. A connection between two neurons, separated by a gap space
12. Cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these function
13. Nerve cells that are activated by sensory input from the environment.
14. Lower negative postsynaptic membrane potential, making action potentials harder
15. useful for the heart
16. glial cells that surround the axon. Insulate, protect, and speed up the travel time of an electrical signal.

1. The process of combining and processing incoming signals at the level of a single neuron to produce an output signal.
2. soon after, K+ channels open and K+ rushes out
3. benefits rest of the body
4. before the synapse, sending the signal
5. Raise positive postsynaptic membrane potential, making action potentials easier
6. when the membrane threshold is reached, voltage-gated Na+ channels open and Na+ rushes in
7. multiple inputs via chemical molecules opening ion channels to generate electric signal
9. the axon is slightly negative (-70mV) compared to the slightly positive space outside the cell
10. after the synapse, receiving the signal
