| Question | Answer |
|---|---|
| What system in the brain is involved in emotion ? | Limbic=emotions, surrounds the deincephalon |
| What surrounds the axon in the CNS and allows to insulated and speed up the signal? | myolin shealth called in CNS= Oligodendrocyte |
| How do you determine cardic output? | Storoke volume x BPM= C.O |
| What happens on the two sides of the capillaries (arterial & venule sides), How does fliud get in and out? | fluid getting in and out of blood depends on concentration of substance) * blood pressure- out of arterial into the tissue *osmotic pressure-in back through venules Lymphatic system picks up extra fluid |
| what is universal blood donor type? Recipient? | O-,AB+ |
| What percentage of blood is plasma? RBC-WBC=? | 55%,45% |
| What are the vessels that supply the neck and head with blood? Drains neck & head? | Carotid, Jugular |
| whats the divisions below the aorta and inferior vena cava into hip & legs both supply & drainage? | Iliac |
| What are two types of cells in the alveoi? | 1. alveolar cell- allows gas exchange next to capillaries cell 2. Surfactin |
| Where does the actual respiration start? | respiratory bronchals- gas exchange begins (ventilation vs respiration-gets air) |
| Basic functional unit in a muscle cell? | Sacromere |
| Two types of PROTEINS that make uo the sarcomere? | Protein strand * Actin- needs CA+ to allow to shift shape to pull myosin across * Myosin- needs ATP to be able to pull head across |
| What causes muscle cell to release all of CA+ to contract? | Acetolcoline (neurotransmitter) |
| Where do you see smooth muscle in body? | Intestines, arteries (CV,Digestive, Urinary) |
| Action Potential | -55 |
| Resting Potential | -70 |
| Depolarization | Na+ rushes in |
| Re polarization | K+ out |
| Na+K+ pump | Resting requires ATP |
| ATP starts | Hillock know to send signal |
| Dendrite | Receives signal for another neuron |
| Excitatory (EPSP) or Inhibitory (IPSP) | post synaptic potential |
| Na+ goes in (inhibit or excite) | neurotransmitters |
| ACH | Skeletal muscle, movement |
| GABA | Goes into brain, inhibitory |
| Adrenalin | adrenal |
| Na+ causes | release of increase neurotransmitters and that will incite or inhibit the next neuron |
| Brain | cerebrum: lobes( frontal, parietal, temp-olfaction(auditory) |
| Frontal lobe | prefrontal area- personality, cognition, decision-making |
| Parietal lobe | Somatosensory and association areas: interpreting touch, temp, pain, sensations (skin) |
| Temporal lobe | long term memory formation, auditory, word identification/comprehension, Interpreting/ remembering smells, emotions |
| Occipital lobe | Vision and association areas |
| Insula lobe | language,balance |
| Diencephalon- Thalamus: | Two large oval masses integrates, filters and prioritizes all formation goin to cerebral cortex |
| Diencephalon-Hypothalamus: | Controls autonomic nervous system Controls physical response to emotions Regulation of body temp Regulation of hunger/satiety and thirst Regulation of sexual behavior Help regulate sleep/wake cycles Controls secretion from pituitary gland |
| Diencephalon-Brain Stem: | Medulla-Vital, heart& lungs Pons -relaxtion, connection for cerebellum(muscle signals) -all muscle signals from cerbrum & diencepholn have to go thru cerebrum to coordinate muscle action |
| Periephral Nervous System Sympathetic : | highly alert, "fight or flight" beta brain waves |
| Periephral Nervous System Parasympathetic: | Inhibitory, most of time we spend life in this mode, visceral active, digestion, urinary activity, muscles are relaxed |
| Cardiovascular R-Wave: | main activity, ventricle contracting ventricular depolarization |
| P-Wave: | atrial depolarization |
| T-Wave: | Ventricular re polarization |
| SA Nodes: | In atria |
| AV Nodes: | Atria ventricular |
| AV bundle: | Down middle of HEART |
| Purkinji Fibers: | cause ventricles to contract |
| Hepatic Portal System: | Blood flow through messentaries goes to liver first to detoxify the process of the substances . |
| H.P.V: | delevers to liver, drain into inferior vena cava directly to HEART |
| Boyles Law: | Air in lungs- inverse |
| Inspiration: | Pressure decrease, Volume increase (chest expand) |
| Expiration: | Pressure increase, Volume decrease (diaphram relax) |
| P.V.= | PCO2,PO2 (Partial Pressure) |
| Aveoli->Blood->Cells: | Depends on increase(PCO2, PO2) |
| Obstructive Disease: | Block airway. ex asthma, bronchitis |
| Restrictive Disease: | Respiratory & alveoli not able to work |
| All together: | Called chronic obstructive pul. disease |
| How the cell can determine if its a part of your body or someone else? | Protein Carbohydrate Marker |
| Epithelial Tissue:Squamous: | Flat, irregular cells |
| Epithelial Tissue:Cuboidal: | cube-shaped cells |
| Epithelial Tissue:Columnar: | Tall, rectangular cells |
