Hydrogen, Oxygen, Nitrogen
\.The smallest unit of an element that still retains the chemical and physical properties of the
element is called: - Answer- Atom

\.What is pH? - Answer- a measure of hydrogen ion concentration
,\.Anterior position - Answer- a body part is located towards the front (ventral)
\.Posterior position - Answer- a body part is located toward the back. (dorsal)
\.Superior position - Answer- a body part is located ABOVE another part or towards the head
\.Anatomy - Answer- structure as well as its relationship with other structure

\.Proximal - Answer- a body part is CLOSER to a specific point of origin or attachment or
closer to the trunk of the body
\.Distal - Answer- a body part is FARTHER from the specific point of the origin or attachment
\.Superficial -external - Answer- a body part is located near the surface
\.Deep (internal) - Answer- a body part is located away from the surface
\.A sagittal plane (median) cuts the body - Answer- right down the middle
