Document Summary
Anatomy- the study of the physical structures of the body and the relationships among body structures. Physiology- the study of the function of body structures and their complex interactions. Homeostasis- the ability to maintain a relatively stable internal environment; allows the body to maintain a physiological parameter, such as body temperature, in a normal range around a predetermined set point. Example: body corrects an increase in body temperature by sweating. Negative feedback- opposes the original stimulus; thus minimizes the change that activated the system. Works to return the system back to its normal set point. Positive feedback- enhances the change that initiated the response. Standard anatomic position- specimen is presented facing forward, toes pointing forward, the feet shoulder width apart and palms facing forward. Important because it creates a standard point of reference that facilitates communication among science and health care professionals. Sagittal plane- cut down from head to feet in right or left side.
