psk4u Quizz #1 Anatomy

Anatomical Position

Body standing upright, facing forward, arms at sides, palms facing forward, and feet together.

Superior

Above; for example, the head is superior to the chest.

Inferior

Below; for example, the stomach is inferior to the heart.

Anterior (ventral)

Front; for example, the chest is anterior to the spine.

Posterior (dorsal)

Back; for example, the spine is posterior to the sternum.

Medial

Toward the midline of the body.

Lateral

Away from the midline of the body.

Proximal

Closer to the trunk or origin;

Distal

Farther from the trunk or origin.

Superficial

Near the surface of the body.

Deep

Further from the surface of the body.

Flexion

Bending or decreasing the angle between two parts.

Extension

Straightening or increasing the angle between two parts.

Abduction

Moving away from the midline of the body.

Adduction

Moving toward the midline of the body.

Pronation

Turning the palm down.

Supination

Turning the palm up.

Inversion

Turning the sole of the foot inward.

Eversion

Turning the sole of the foot outward.

Dorsiflexion

Movement that brings the toes up toward the shin.

Plantarflexion

Movement that points the toes down.

Rotation

Turning of a body part; medial rotation turns inward, lateral rotation turns outward.

Circumduction

Circular movement of a limb.

Longitudinal Axis

Runs top to bottom and is the axis around which rotation occurs.

Horizontal (Transverse) Axis

Runs left to right; flexion/extension occurs around this axis.

Anteroposterior (Sagittal) Axis

Runs front to back; abduction/adduction occur around this axis.

Sagittal Plane

Divides the body into left and right sections; associated with flexion and extension.

Frontal (Coronal) Plane

Divides the body into front and back sections; associated with abduction and adduction.

Transverse (Horizontal) Plane

Divides the body into top and bottom sections; associated with rotation movements.
