gross anatomy - ANSWERS-large structures such as the brain
microscopic anatomy - ANSWERS-structures too small to be seen with the naked eye
What are the levels of structural organization of the human body in order?- ANSWERS-
chemical, cellular, tissue, organ, organ system, organism
homeostasis - ANSWERS-process by which organisms maintain a relatively stable
internal environment
positive feedback loop - ANSWERS-results in a change in the body's status, rather than
a return to homeostasis ex. normal childbirth
negative feedback loop - ANSWERS-resists a change to bring back to homeostasis
what controls the negative feedback loop? - ANSWERS- the brain
, is positive feedback or negative feedback more common ex. body temperature, blood
and glucose levels, pH levels in the blood?- ANSWERS- negative feedback loop
what are the four basic parts of the negative feedback loop in order?- ANSWERS-
stimulus, sensor, control, effector
stimulus - ANSWERS-initial change in condition
sensor - ANSWERS-detecting the deviation from homeostasis
control - ANSWERS-nueral response ordering action (when homeostasis gets out of
balance)
effector - ANSWERS-action to return to homeostasis example is sweating
magnetic resonance imaging (MRI) - ANSWERS-uses a strong magnetic field to study
differences in soft tissue
what is an MRI used for?- ANSWERS- brain scans, muscle and tendon injury
positron emission tomography (PET) scan - ANSWERS-uses a dye with radioactive
tracers, injected or ingested, used to look at the overall functioning or physiological
activity ex. the digestive tract (drink fluid and watch the activity of that physiology
throughout the body)
what is a PET scan used for- ANSWERS- Alzeimers
sonography - ANSWERS-ultrasound imaging, uses sound waves, very safe, can see
overall structures in both bone and soft tissue
parietal pleura - ANSWERS-membrane that lines the thoracic cavity
visceral pleura - ANSWERS-covers the lungs
