| Question | Answer |
|---|---|
| muscle tissue | controls internal and external movement |
| epithelial tissue | covers surface of body and lines internal organs |
| connective tissue | holds organs in place and binds different parts of the body together |
| nervous tissue | recieves messages from the body's internal and external enviroment |
| threshold | minimum level of stimulus to activate a neuron |
| action potential | firing of a neuron |
| acetyl choline | used in thought and muscles |
| epinephrine | excitedtory/ vasoconstrictor |
| seratonin | mood and sleep |
| dopamine | pleasure neuron |
| the central nervous system | brain and spinal cord; processes information |
| the peripheral nervous system | picks up stimuli from the outside enviroment; sends to central nervous system |
| vision | sensing light with your eyes |
| pupil | opening that regulates the amount of light entering the eye |
| lens | focuses the object |
| retina | contains rods and cones |
| rods | black and white vision |
| cones | color vision |
| hearing | picking up sound vibration |
| cochlea | hair cells inside produce nerve impulses in response to vibration |
| semicircular canals | responsible for balance |
| ligament | attaches bone to bone |
| tendon | attaches muscle to bone |
| skeletal muscle tissue | striated-voluntary; attaches to bone; can be involuntary |
| smooth muscle tissue | involuntary; (digestive tract) |
| cardiac muscle tissue | myocardium, involuntary |
| muscle contraction | the sliding filament theory |
| neuromuscular junctions | neuron controls muscle contraction |
| the skin | serves as a barrier against infectio, regulates temp., secretes waste, UV protection |
| epidermis | outer layer, contains melanosytes |
| dermis | inner layer, has cologen, blood vessels, nerve endings, glands, sense organs, smooth muscles, hair folicles |
| antigen | disease causing agent, viruses and bacteria |
| second line of defense | inflammatory response; white blood cells go to area vaso-constrict bacteria so body cannot tell difference between pierced and unpierced skin so it always gets hot |
| first line of defense | skin; non-specific (keeps everything out) |
| B cell | makes antibodies |
| antibody | surround "bad guys"; combine with antigens |
| helper T cells | activate other helper T's and B cells |
| cytotoxic T cells | attack imbaded cells |
| active immunity | body produces antibodies from getting sick or from a vaccine |
| passive immunity | antibodies are injected or you get them from mom |
| allergic response | the antigen binds to an antibody that binds to a mast cell mast cells secret histimines |
| hormones | keeps the body in homestatis |
| hypothalamus | controls the pituitary gland and is responsible for the flight or fight response |
| pituitary gland | secrets hormones |
| antidiuretic hormone (ADH) | responsible for water resbsorbtion in the kidney |
| oxytocin | controls ejection of milk |
| follicle-stimulating hormone | stimulates production of egg and sperm |
| luteinizing hormone (LH) | causes a release of the egg |
| thyroid-stimulating hormone (TSH) | stimulates the release of the thyroxine from the thyroid gland |
| adreno-corticotropic hormone (ACTH) | release of hormones from the adrenal glands |
| growth hormone (GH) | protein synthesis and growth in cells |
| prolactin | milk production |
| thyroid gland | regulates metabolism |
| thyroxin | (hormone) responsible for metabolism |
| calcitonin | puts calcium from blood into bones |
| parathyroid gland | homoestasis of calcium |
| parathyroid hormone (PTH) | takes calcium out of bone and into blood |
| adernal glands | prepare for and deal with stress |
| cortisol | (hormone) repsonsible for metabolism of carbs, lipids, and proteins |
| aldosterone | (hormone) sodium/potassium balance in kidney |
| epinephrine | increase heart and blood pressure |
| pancreas | makes enzymes and hormones |
| Islets of Langerhand | have alpha and beta cells |
| insulin | produced by beta cells; puts glucose into cells and muscles |
| glucagon | produced by alpha cells; changes glycogen into glucose |
| the circulatory system | heart, blood vessels, blood |
| myocardium | heart muscle; beats in unison |
| sinoatrial node | pacemaker; controls heartbeat |
| blood vessels | aterie-arterioles-capillaries-venules-veins |
| arteries | are thick and elastic so it can handle pulse of blood |
| veins | one way valves; take blood back to the heart |
| blood pressure | pressure from the heart on the vessels |
| systolic | first hit of blood on the arterie walls |
| diastolic | free flow of blood into the aterie |
| heart attack | blocks ateries; symptoms:difficulty breathing, nausea |
| stroke | blood clot breaks free and gets stuck in the brain |
| hypertension(?) | high blood pressure |
| erythrocytes | RBC (45% of blood is RBC) |
| hemoglobin | carrys O2 and contains iron |
| plasma | fluid in blood 55% |
| platelets | clot blood 1% |
| the lymphatic system | network of vessels that collect fluid once it leaves the circulatory system |
| air pathway | nose/mouth- nasal cavity- pharynx- larynx- trachea- bronchi- bronchioles- alvedarducts- aveoli |
| aveoli | air sacs where you change O2 and CO2 |
| bulimia | binging and purging |
| anorexia | not eating |
| cirrhosis | scar tissue on the liver from detoxifying |
| diabetes | insulin target cells do not respond (type #2) |
| kidney | filters uria out of the blood |
| nephron | 1 million per kidney |
