Document Summary

Anatomy: study of the structure of the body. Physiology: study of the function of the body. The principle is what a structure can do depends on its specific form. Cellular level: cells are made up of molecules. Tissue level: tissues consist of similar types of cells. Organ level: organs are made up of different types of tissues. Organ system level: organ systems consist of different organs that work together closely. Organismal level: the human organism is made up of organ systems. Axial skeleton (blue): axis around which the body moves. Anatomical position: standing, facing forward, palms of hands facing forward. Describes structures relative to each other in the vertical exis of the body. Describes structures relative to each other in terms of the middle of the body. Ex: the arm is lateral to the sternum. Used to describe locations on extremities (upper limb, lower limb) Start of the extremity versus end of extremity.
