VELASCO Week 7
Nervous System
| Question | Answer |
|---|---|
| The brief period during which a local area of an axon's membrane resists re-stimulation is called the __________ period. | Refractory |
| The difference in electrical charge between the inside and outside of a membrane is called the membrane potential. | TRUE |
| A membrane that exhibits a membrane potential is said to be | Polarized |
| There are two types of synapses—the electrical synapse and the __________ synapse. | Chemical |
| Movement of the membrane potential away from zero (below the usual RMP) is called | Hyperpolarization |
| The membrane potential maintained by a nonconducting neuron’s plasma membrane is called the _____ membrane potential. | Resting |
| If the magnitude of the local depolarization surpasses a limit called the _____, voltage-gated Na+ channels are stimulated to open. | Threshold Potential |
| The tiny bulge at the end of a terminal branch of a presynaptic neuron’s axon is called a(n) | Synaptic Knob |
| The active transport mechanism in the plasma membrane that transports sodium and potassium ions in opposite directions and at different rates is the | sodium-potassium pump |
| A membrane that exhibits a membrane potential is said to be | polarized |
