|---|---|
| Plasma | Take nutrients and proteins to parts of the body. |
| Cytoplasm | Fills the inside of cells |
| Interstitial Fluid | Fluid found in the spaces around cells. Determines internal environment. |
| Basement membrane | A small mat of fibers that creates space for only small microbes to get through. |
| Homeostasis | Keeping an organism's internal environment constant even when the external environment changes. |
| Internal Environment | Interstitial Fluid most cells live in |
| External Environment | Environment outside of the body |
| "Itis" | Suffix for Inflammation |
| Innate Immunity | Body's first response of the immune system |
| Microphages | Eat debris and microbes "Big Eaters" |
| NK cells | Lymphocytes that kill other cells infected by microbes |
| Neutrophils | Phagocytose and explode to release oxide that kills viruses. Realizes a net of DNA "Little eaters" |
| Capillary | Provides nutrients and Oxygen to cells |
| Adaptive Immunity | Classic immune system: built up immunity as we are exposed to diseases. |
| Reye's Syndrome | Happens when taking aspirin for the flu |
| Encephalitis | Brain inflammation |
| Meningitis | Inflammation of the fluid and membranes surrounding the brain |
| Pain | Warning that a tissue is damaged and could be damaged further by continued use |
| Visceral | Internal/ deep |
| Periosteum of Bones | Layer around the bones with cells, blood, and nociceptors |
| Nociceptive receptors | only relates pain, and immediately sends signal. Type A pain. |
| Sensory Signals | Go up to the brain |
| Motor signals | Go down from the brain |
| Ischemia | Lack of blood flow |
| Hypoxia | Not enough oxygen |
| Type A neurons | Sharp pain and rapid immediate signal to the rain, triggers reflex, direct damage to nerves. |
| Idiopathic | Unknown cause of pain |
| Excitoxic | Neurons excited (overstimulated) to death |
| Phantom Pain | Feeling pain in a no longer existing limb |
| NSTAIDS | Non-Steroidal Anti-Inflammatory Drugs |

| Exogenous | Eternal existing pain killers (acetaminophen) |
| Placebo Effect | idea that believing is seeing |

| Action Potential | Nerve impulse |
| Resting Membrane potential | Polarized distribution of charges |
| Action Potential Propagation | Depolarization of charges |
| Nerve-muscle synapse | acetylcholine released by an axon |
| Nerve-nerve synapse | acetylcholine, epinephrine, dopamine, GABA, and endorphins released by axon. |
| Naloxone | treatment to opoiod overdose |
| Central Nervous system | Brain and spinal chord |
| Peripheral Nervous system | Connects CNS nerves to peripheral organs, muscles, glands, sensation detectors Etc... |
| Somatic Nervous System | skeletal muscles stimulated |
| Autonomic Nervous System | regulates internal organs. I.E. digestive, circulatory, urinary, reproductive systems. (automatic) divided into the Sympathetic and Parasympathetic systems |
| Sympathetic Division | "Fight or flight" Coordinates expenditure of energy, signals originate to spinal cord (thoracic region) and release epinephrine. |
| Parasympathetic Division | "Rest and Digest" Coordinates restoring energy, signals original to the brainstem, releases acetylcholine |
| Type C neurons | Dull aching pain, slow sending signal. |
