| 1965247399 | Cell Body | nucleus surrounded by cytoplasm | 0 | |
| 1965247400 | Nissal Bodies | clusters of rough endoplasmic reticulum | 1 | |
| 1965247401 | Endoplasmic Reticulum | manufactures proteins | 2 | |
| 1965247402 | Dendrites | short branches off the cell body and receives information | 3 | |
| 1965247403 | Axon | generates &carries action potential | 4 | |
| 1965247404 | Axon Hillock | cone shaped area adjacent to cell body | 5 | |
| 1965247405 | Axon Terminal | end of the axon | 6 | |
| 1965247406 | Myelin Sheath | Lipid layer that surrounds parts of the axon. Speeds up the action potential as it travels down the axon | 7 | |
| 1965247407 | Nodes of Ranvier | gaps between myelin | 8 | |
| 1965247408 | Neurilemma | Plasma membrane surrounding neuron | 9 | |
| 1965247409 | Multipolar Neuron | -Most common -found in brain & spinal cord -many processes extending from cell body (many dendrites and one axon) | 10 | |
| 1965247410 | Bipolar Neuron | -found in the retina and inner ear -Two processes from cell body (one dendrite and one axon) | 11 | |
| 1965247411 | Unipolar Neuron | -found in sensory neurons -one process extending from cell body | 12 | |
| 1965247412 | Nuclei | (CNS Neuron) clusters of cell bodies | 13 | |
| 1965247413 | Tracts | (CNS Neuron) bundles of neuron processes | 14 | |
| 1965247414 | Ganglia | (PNS Neuron) clusters of cell bodies | 15 | |
| 1965247415 | Nerves | (PNS Neuron) bundles of neuron processes | 16 | |
| 1965461808 | Classifications of Neuron | -Longevity -Amitoric: can't undergo cell division -High metabolic rate: neurons contain a lot of glucose in order to obtain energy -Generate and conduct action potentials | 17 | |
| 1965461809 | Neurons | Nerve cells | 18 |
