| Question | Answer |
|---|---|
| axon | the 'tail' of the neuron cell. carries information away from the cell, towards another cell in order to communicate. |
| blood-brain barrier | selective barrier in the blood vessels in the brain that attempts to keep toxic substances away from neurons |
| brainstem | lower part of the brain, connects the brain with the spinal cord, responsible for your vital functions (heart rate, breathing, etc). |
| CNS | central nervous system (brain and spinal cord) |
| cerebellum | posterior part of the brain that maintains balance and physical actions that are 'memorized' |
| CSF | cerebrospinal fluid |
| dendrite | arms of the neuron that receive information from other neurons |
| cerebral cortex | outer part of the brain, contains neuronal connections mostly unique to human life (self awareness, speech, logic, problem solving) (your fingers wrapped around your thumb) |
| meninges | protect membrane that surrounds your CNS, filled with CSF |
| myelin sheath | cells that flatten out like pancakes and wrap around axons to protect them and help them communicate more efficiently with their neighbors |
| nerve | a bundle of neurons that run together |
| PNS | peripheral nervous system, all the nerves (neurons) in your body that are not part of the brain or the spinal cord |
| synapse | the area where two neurons connect (and hold hands) |
| ventricles of the brain | canals, or spaces, in the brain that contain CSF |
| sympathetic nervous system | your fight or flight system |
| parasympathetic nervous system | your rest and digest system |
| encephal/o | brain |
| gli/o | glial cells (small cells that support neurons in the nervous system, hold neurons together like 'glue' and help create the blood-brain barrier) |
| mening/o | meninges |
| my/o | muscle |
| myel/o | spinal cord |
| neur/o | nerve |
| -algesia | excessive sensitivity to pain |
| -algia | pain |
| comat/o | sleep |
| -esthesi | feeling |
| -kinesia -kinetic -kinesis | movement |
| -phasia | speech |
| -plegia | paralysis |
| -praxia | action |
| -syncop/o | to cut off |
| syncope | to faint (cut off consciousness) |
| efferent | moving away from |
| afferent | moving towards |
