anatomy - ANSWERS-study of structure and form; derived from Greek word Anatome
which means to cut apart or dissect; Anatomists study structure and form of organims
studying the relationships among parts of the body and the structure of individual
organs
physiology - ANSWERS-the study of function of the body parts; physiologists examine
how organs and body systems function under normal circumstances as well as how
their functions are altered with medication or disease
branches of anatomy - ANSWERS-microscopic- structures that cannot be observed to
the unaided eye
(cytology- study of body cells and their internal structure;
histology- study of tissues)
gross anatomy- structures that can be observed to the unaided eye,; macroscopic
(systemic anatomy- anatomy of each body system;
regional anatomy- examines all of the structures in a particular region of the body as a
complete unit)
homeostasis - ANSWERS-refers to the ability of an organism to maintain a consistent
internal environment or "steady state"; for example if the body gets hot due to external
temperature, the body maintains a steady state by circulating more blood toward the
surface to facilitate heat loss; nervous system regulating blood pressure when you get
out of bed in the morning
, receptor- detects changes in variable; either substance or process stimulus
control center - interprets input from the receptor and initiates change through the
effector; parathyroid hormone monitors calcium levels
effector- structure that brings about the change to alter the stimulus; muscles in the
lungs that bring air flow
positive feedback - ANSWERS-set point-- what is normal
action occurs that reinforces the response; mother breast feeds baby: suckling causes
receptors to signal to hypothalamus to release oxytocin causing breast tissue to
produce milk
negative feedback - ANSWERS-detecting a change and then initiating the opposite
response to return to the set point (if it's hot, bringing heat to the surface of the skin so
the body loses heat, if cold withdrawing blood to vessels, skeletal muscles shiver, no
sweat, withdraw foot when stepping on glass)
atoms - ANSWERS-protons (+1 charge), nuetrons, and electrons (very little weight)
atomic number is based on protons
amu is based on protons and nuetrons
types of chemical bonds - ANSWERS-ionic bond- bond that transfers electrons,
stronger; form salts
covalent bond- bond that shares electrons, weaker, can be single, double, triple; form
molecular compounds
major elements of the human body - ANSWERS-Oxygen (65%), Carbon(18), Hydrogen
(10), Nitrogen (3), Calcium, Phosphorous,
cation - ANSWERS-positively charged ion
anion - ANSWERS-negatively charged ion
