| Define neurons | Basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances. |
| What are the types of neurons? | sensory, motor, and interneurons. |
| Define sensory neurons | Sensory nerves carry signals to your brain to help you touch, taste, smell and see. |
| Define motor neurons | Motor nerves carry signals to your muscles or glands to help you move and function. |
| Define interneurons | They connect motor and sensory neurons and send signals between neurons. |
| What are the parts of a neuron? | Dendrites, soma, body, axon, myelin sheath, nodes of Ranvier, axon terminal and synapse. |
| Define action potential | A temporary shift (from negative to positive) in the neuron's membrane potential caused by ions suddenly flowing in and out of the neuron. |
| Define synaptic transmission | Process by which a neuron communicates with a target cell across a synapse. |
