| Question | Answer |
|---|---|
| Synapse | The place where signals are transmitted from one neuron, called the presynaptic neuron, to another neuron, called the postsynaptic neuron. |
| Resting Potential Neuron (voltage) | `70mV |
| Nerve Impulse (speed) | myelinated- fast; unmyelinated- slow |
| Repolarization | when the peak of the action potential is reached and the membrane potential begins to move back toward the resting potential |
| Refraction | brief period during which a local area of an axon’s membrane resists restimulation |
| Saltatory Conduction | where the action potential seems to “leap” from node to node along myelinated fibers |
| Medulla oblongata | Integration of cardiac, vasomotor (vessel muscle), respiratory, digestive and other reflexes |
| Ventral Nerve Root | Carries motor information out of the spinal cord |
| Dynamic Equilibrium | The ability to detect changes in both the direction and the rate at which movement occurs |
| Thyroid | regulates metabolism |
