|---|---|---|---|---|---|
| Central NS | Brain and Spinal Cord
🗑
|
||||
| Peripheral NS | 12 cranial nerves. 31 spinal nerves. Afferent division. Efferent division.
🗑
|
||||
| Afferent | Sensory
🗑
|
||||
| Efferent | Motor
🗑
|
||||
| Somatic | Pertaining to the body. Sensory information communicated through spinal cord.
🗑
|
||||
| Visceral | Surrounding
🗑
|
||||
| Ganglia | Neuron
🗑
|
||||
| Dendrite | Carries impulses from synapse to cell.
🗑
|
||||
| Axon | Carries electrical signals away from the cell. Cyatic nerve has largest axon. Axons are shorter in the upper body. Very sensitive to acidosis.
🗑
|
||||
| Astrocytes | #1 tumor because of cell structure. Form blood brain barrier.
🗑
|
||||
| Microglia | Pac Man of brain. Sensitive to acid/base imbalance. In imbalance start eating good cells. Need to keep controlled.
🗑
|
||||
| Oligodenrocyes/Oligodendroglia | Support of cell. Mylen sheath. Message sending ability. Don't like exposure to viral infection, will permanently alter oligis. Viral menengitis,
🗑
|
||||
| MS | rejects new mylen sheath.
🗑
|
||||
| Ependyma | Line the ventricles (tanks that hold CSF) Allow for movement, progression in brain. Single layer cells of cells also on spinal cord.
🗑
|
||||
| Neurotransmitters | Acetylcholine, Dopamine, Norepinephrine, Seratonin, GABA, Aspartate, Glutamic, Glycine
🗑
|
||||
| Acetylcholine | Main neurotransmitter, making motor/movement. Defecit - Alzheimers, parkinsons, speech blockage.
🗑
|
||||
| Dopamine | Think psych. turn off of message sending. Increased dop. - ticks.
🗑
|
||||
| Norepi | Neurotransmitter of most of sypathetic NS, released from adreanal medula. Increased - anxious.
🗑
|
||||
| Seratonin | Increased - sedation. Decreased - depression.
🗑
|
||||
| GABA | Acid. Natural valium. Increased - coma. Decreased - Anxiety. Very fickle - likes acid/base balance. Hung up on K+
🗑
|
||||
| Aspartate | Acid. Excitatory. Changes memory.
🗑
|
||||
| Glutamic | Excitatory. H2O 'hog'. Too much makes brain swell.
🗑
|
||||
| Glycine | Excitatory in brain, Inhibatory everywhere else.
🗑
|
||||
| Neuro Peptides | Somatostatin, Endorphins, Substance P, Histamine
🗑
|
||||
| Somatostatin | Protects growth hormone. Possible cause of Alzheimers when it runs out. Needs to cross blood brain barrier.
🗑
|
||||
| Endorphins | Analgesia effect. High endorphin response causes seizures, too much stress.
🗑
|
||||
| Substance P | Excitable. Tendency to aggrivate microglia - panic. Controlled with acid/base balance. Prevent cascade if gotten under control.
🗑
|
||||
| Histamine | Alertness. regulated by fluid onboard. (antihistamine with cold med. - get sleepy). Body makes as you need it. Goes out of control in trauma.
🗑
|
||||
| Hormones | ACTH, ADH, Leptin, Ghrelin, PYY
🗑
|
||||
| ACTH | Hypothalamus - production of adreanal or corticosteroid/glucocorticoid - too much sugar - acid. Anterior pituitary.
🗑
|
||||
| ADH | Absorption. Fluid excretion. Released from anterior pit, sythesized in hypothalamus.
🗑
|
||||
| Leptin | Appetite stimulant (in chocolate). Causes decrease in dopamine. (Parkinson's pts don't eat chocolate).
🗑
|
||||
| Ghrelin | Increase hunger, decrease fat utilization. From kidney, placenta, hypothalamus. Stomach stimulates, by pass pts. loss this part of the stomach.
🗑
|
||||
| PYY | Tells stomach that it is full. Hypothalamus.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
