The Anatomical Planes
Movements and descriptions of the body use anatomical planes as references.

3. Anatomical Plane Definitions
Coronal (Frontal): A vertical plane running from side to side, dividing the body into anterior and posterior portions
Sagittal (Lateral): A vertical plane running from front to back, dividing the body into left and right portions

4. Anatomical Plane Definitions (cont.)
Axial (Transverse): A horizontal plane dividing the body into superior and inferior portions (see text Figure 14-12)

Directional Terms
Medial is toward the midline; lateral is away from the midline
Proximal refers to nearest to the trunk; distal is farthest away from the trunk
Inferior means below; superior means above

Articular System
A series of joints that allow movement of the human body
Joints provide two main functions: motion and stability
There are three classifications: synarthroses, amphiarthroses, and diarthroses

Synarthroses
A joint that lacks a synovial cavity and is held closely together by fibrous connective tissue
An immovable joint
Three structural types: sutures, syndesmoses, and gomphoses

Amphiarthroses
Type of joint in which bones are connected by hyaline cartilage or fibrocartilage
A slightly movable joint

10. Copyright ©2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED.
Diarthroses
A type of joint that connects bones by hyaline cartilage separated by a joint cavity
Freely movable joints
Six different types: pivot, gliding, hinge, condyloid, ball-and-socket, and saddle

11. Movements of Diarthroses
Ranges of motion vary from a single direction to complete motion in three dimensions.

Flexion and Extension
Flexion decreases and extension increases the angle between bones.

13. Abduction and Adduction
With abduction, a limb moves away from the midline. Moving a limb toward the midline is called adduction.

Rotation
Rotation describes bones that turn around their axes, either toward, away from, or around the midline.

Circumduction
With circumduction, an entire limb or portion of a limb moves in a circle around an axis.

16. Supination and Pronation
Supination is the turning of the palm upward; pronation turns the palm downward. The foot performs similar movements, but not as completely.

17. Plantar Flexion and Dorsiflexion
The foot is extended with toes pointing downward in plantar flexion.
The foot is flexed with the toes upward toward the lower leg in dorsiflexion.

18. Inversion and Eversion
With inversion, the sole of the foot is turned inward; eversion turns it outward.

19. Protraction and Retraction
Protraction refers to moving a body part forward, and retraction backward, within a transverse plane.
Copyright ©2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED.

20. Elevation and Depression
Elevation is lifting a body part upward, and depression is moving a body part downward, along a frontal plane.
