Applied Learning Outcomes
Directional terms describe: • the relative location of different
body features
• the ways the body can be viewed along imaginary lines
Directional orientation•explains a particular view of a person
Directional planes •views of imaginary lines sliced through a person

DIRECTIONAL ORIENTATION
Chapter 1 – Overview of the Body
DIRECTIONAL ORIENTATION
•Inferior, or caudal, refers to a location near the feet.
•Anterior, or ventral, refers to the front of the human body.
•Posterior, or dorsal, refers to the back of the human body.
Chapter 1 – Overview of the Body
Directional planes
Directional planes are views of imaginary lines sliced through a person.
•A sagittal section slices the body vertically into left and right sections.
•A midsagittal section slices the body into equal left and right halves.
Chapter 1 – Overview of the Body
Directional planes
•A frontal, or coronal, section slices the body vertically into anterior and posterior sections.
•A transverse section slices the body horizontally into inferior and superior sections.

Human Body Orientation
Flexion: to bend a joint
Extension: to straighten a joint
Chapter 1 – Overview of the Body
Human Body Orientation
Abduction: movement of the arm or leg away from the midline of the body
Adduction: movement of the arm or leg toward the midline of the body
Chapter 1 – Overview of the Body
Human Body Orientation
Eversion: movement of the hand or foot so that the thumb or great toe moves away from the midline of the body
Inversion: movement of the hand or foot so that the thumb or great toe moves toward the midline of the body
Chapter 1 – Overview of the Body
Human Body Orientation
• Antagonistic: Opposing movements
Flexion Extension
Abduction Adduction
Inversion Eversion
Chapter 1 – Overview of the Body
Body Regions and Cavities
• Body regions are divided into general locations, abdominopelvic regions, and quadrants
Chapter 1 – Overview of the Body
Body Regions and Cavities
• Abdominopelvic regions include nine sections that divide up the abdominal and pelvic portions of the body.
Body Regions and Cavities
• Quadrants section the abdominal region into four portions.
Chapter 1 – Overview of the Body
Body Regions and Cavities
• The human body is naturally divided into internal cavities
• The body cavities contain specific body structures. (You will receive a list of these structures later)

Summary
Directional terms describe • the relative location of different body features• the ways the body can be viewed along imaginary linesPosition terms explain• how a patient should be positioned for a procedureMovement 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
