Anatomical Terms Terms and Definitions

Bell Work: Define the Regions

Standard 12 and 13: Outline the in-depth normal structure and function Outline the bony anatomy and organ structures of the musculoskeletal, digestive, cardio-respiratory systems specifically as they relate to radiology. Review directions, planes, and sections of the body in order to perform radiographic images. Summarize appropriate medical text(s) in order to list signs and symptoms of common diseases and disorders associated with each system.

Objectives Classify the anatomical terms of movement Unit III

Anatomic Terminology Anatomic position Erect, face forward, feet together, arms at sides with palms forward Unit III

Anatomic Terminology Plane Flat surface passed through the body or a portion of the body Longitudinal planes Coronal Sagittal Horizontal plane Transverse transverse mid-sagittal coronal Unit III

Directional Terms anterior posterior lateral cephalad cephalic superior cranial posterior anterior lateral proximal inferior caudal caudad medial distal Unit III

Abduction vs Adduction Abduction is any motion of the limbs or other body parts that pulls away from the midline of the body.  Adduction is the movement of a body part toward the body's midline. So, if a person has their arms straight out at the shoulders and brings them down to their sides, it is adduction Unit III

Joint Movement Terms ABDUCT vs. ADDUCT Unit III

Flexion and Extension Flexion and extension are movements that occur in the sagittal plane. They refer to increasing and decreasing the angle between two body parts: Flexion refers to a movement that decreases the angle between two body parts. Flexion at the elbow is decreasing the angle between the ulna and the humerus. When the knee flexes, the ankle moves closer to the buttock, and the angle between the femur and tibia gets smaller. Unit III

Extension Extension refers to a movement that increases the angle between two body parts. Extension at the elbow is increasing the angle between the ulna and the humerus. Extension of the knee straightens the lower limb. Unit III

Joint Movement Terms FLEXION vs. EXTENSION hyperextend flexion flexion dorsiflexion plantar flexion neutral Unit III

Dorsiflexion vs. Plantarflexion Dorsiflexion refers to flexion at the ankle, so that the foot points more superiorly. Plantarflexion refers extension at the ankle, so that the foot points inferiorly. Unit III

Inversion and Eversion Inversion and eversion are movements which occur at the ankle joint, referring to the rotation of the foot around its long axis. Inversion involves the lateral rotation of the foot, such that the sole points medially. Eversion involves the medial rotation of the foot, such that the sole points laterally. Unit III

Joint Movement Terms INVERSION vs. EVERSION turn inward or medially turn outward or laterally Unit III

PRONE AND SUPINE Prone: Position of lying on the anterior part of the body. Patient lies on stomach with head turned to the side. Supine: Position of lying on the posterior part of the body. Patient lies flat on back. Additional supportive devices may be added for comfort.

PRONATION vs. SUPINATION Joint Movement Terms PRONATION vs. SUPINATION place on front place on back Unit III

Rotation Rotation of the neck or body is the twisting movement produced by the summation of the small rotational movements available between adjacent vertebrae Unit III

Lateral and Midline Rotation Movement that brings the anterior surface of the limb toward the midline of the body is called medial (internal) rotation Anterior surface moves away from the midline is lateral (external) rotation Unit III

Circumduction is the movement of a body region in a circular manner, in which one end of the body region being moved stays relatively stationary while the other end describes a circle Unit III

ROTATION vs. CIRCUMDUCTION Joint Movement Terms ROTATION vs. CIRCUMDUCTION pivot circle Unit III

Elevate and Depress Elevate: Move Upward Depress: Move Downward Unit III
