This chapter introduces key anatomical concepts and terminology. It covers directional terms that describe the body's orientation in space, positional terms for medical procedures, and movement terms for different motions. The major body regions and cavities are defined, dividing the body into mapped locations. Understanding these anatomical concepts is important for accurately communicating about the structure and function of the human body.

9. Summary
Directional terms describe
• the relative location of different body features
• the ways the body can be viewed along imaginary lines
Position terms explain
• how a patient should be positioned for a procedure
Movement terms explain
• a person’s ability to move a body structure in a particular
direction in relation to the center of the body
Body region terms
• create a map of the body locations
• describe the location of pain or injury
Body cavity terms
• create a map of the body structures
• help healthcare workers communicate accurately and
effectively
