What is radioactive isotope? - Atom whose nucleus undergoes degeneration and in the process gives off radiation What is a molecule? - Atoms bonded together to form a chemical unit What is a compound? - Combining different atoms What is ionic bond? - Ions with opposite charges attractWhat are ions? - Particle that is electrically charged because it has gained or lost one or more eletrons What is a covalent bonds? - Atoms sharing electrons instead of losing or gain them What is polar bond? - Bond created when electrons shared by adjacent atoms are shared unequally hydrophilic means - water-living Hydrophobic means - water-fearing What is electrolyte? - Substances that release ions when puts into water What is pH? - a measure of hydrogen ion concentration Anterior position - a body part is located towards the front (ventral) Posterior position - a body part is located toward the back. (dorsal) Superior position - a body part is located ABOVE another part or towards the head Anatomy - structure as well as its relationship with other structure Physiology - function of the body Proximal - a body part is CLOSER to a specific point of origin or attachment or closer to the trunk of the body Distal - a body part is FARTHER from the specific point of the origin or attachmentSuperficial -external - a body part is located near the surface Deep (internal) - a body part is located away from the surface A sagittal plane (median) cuts the body - right down the middle A frontal plane (coronal) is perpendicular (oppose) so it cuts the body - from ear to ear, from shoulder to shoulder across A transverse plane cuts the body - from the navel in half dividing the superior from the inferior A group of similar types of cells that performs a specific function is a(n): - Tissue What is the mechanism called which brings about an increasing change in the same direction?
