Nerves
| Action Potential | Rapid depolarization of the cell that results in propagation of the nerves impulse along the membrane |
| Afferent Nerve | Sensory nerve that carries information from the periphery of the body to the brain or spinal cord |
| Anesthesia | The loss of feeling or sensation resulting from the use of certain drugs or glasses that serve an inhibitory |
| Bell's Paksy | Type of unilateral facial paralysis involving the facial nerve |
| Efferent Nerve | Motor nerve that carries information away from the brain or spinal cord to the periphery of the body |
| Facial Paralysis | Loss of action of the muscles |
| Ganglion/ Ginglia | Accumulation of neuron cell bodies outside the central nerves system |
| Innevation | Supply of nerves to tissues or organs |
| Neuron | Cellular agent form the neuron that is discharged with the arrival of the peripheral nervous system |
| Neurotransmitter | Chemical agent from the neuron that is discharged with the arrival of the action potential, diffuses across the synapse, and binds to receptors on another cell's membrane |
| Nervous System | The extensive, intricate network of structures that activates, coordinates, and controls all functions of the body |
| Resting Potential | Charge difference between the fluid outside and inside a cell that results in differences in the distribution of ions. |
| Synapse | Junction between 2 neurons or between a neuron and an effector organ, where neural impulses are transmitted by electrical or chemical means. |
| Trigeminal Neuralgia | Type of lesion of the trigeminal nerve involving facial pain |
