Question | Answer |
---|---|
Sagittal Plane | Divides the body in left and right halves. |
Coronal Plane (Frontal Plane) | Divides the body into anterior and posterior portions. |
Transverse Plane | Divides the body into superior and inferior portions. |
Cranial | Closer to the head. Used when referring to structures in the trunk. |
Caudal | Closer to the buttocks. Used when referring to structures in the trunk. |
Posterior | Towards the back of the body. |
Anterior | Towards the front of the body. |
Medial | Towards the midline of the body. |
Lateral | Further away from the midline. |
Distal | Farther away from the trunk. Arms and legs only. |
Proximal | Closer to the trunk. Arms and legs only. |
Superficial | Closer to the surface of the body. |
Deep | Farther away from the surface of the body. |
Ventral | Same as anterior, coronal, etc. |
Dorsal | Same as posterior. |
Extension | Movement that straightens or opens a joint. |
Flexion | Movement that bends a joint or brings the bones closer together. |
Adduction | Brings a limb medially toward the body's midline. |
Abduction | Moves limb laterall away from the midline. |
Medial Rotation | Sometimes referred to as internal rotation. Shoulder and hip joints only. Turns the limb inward toward the midline. |
Lateral Rotation | Sometimes referred to as external rotation. Swings the limb away from the midline. |
Rotation | Axial skeleton only. Movement of the head and vertebral column along the transverse plane. |
Circumduction | Shoulder and hip joints only. Cone shaped movement combining flexion, extension, abduction, and adduction. |
Prone | The position of lying faced down on the table. |
Supine | The position of lying face up. |
Sidlying | Lying on your side. |
Lateral Flexion | Axial skeleton only. Example: head or vertebral column bend laterally to the side. |
Supination*Hint: carrying soup. | Pivoting action of the forearm which results in the palm facing upward. |
Pronation | Pivoting action of the forearm that results in the palm facing downward. |
Opposition | Thumb only. Occurs when the thumb crosses the palm toward the "pinkie" finger. |
Inversion*Hint: INward. | Joints of the feet. Elevates the foot's medial side and brings the sole of the foot medially. |
Eversion | Joints of the feet. Elevates the foots lateral side and moves the sole laterally. |
Plantar Flexion*Hint: it would really hurt to do this with plantar warts. | Releve position in dance. |
Dorsiflextion | Opposite of plantar flexion. Example: picking your toes and ball of foot, balancing on your heels. |
Protraction*Hint: PROtrude. | Scapula, clavical, head, jaw. Occurs when one of these structures moves anteriorly. |
Retraction*Hint: RETReat | Scapula, clavical, head, jaw. Occurs when one of these structures moves posteriorly. |
Elevation | Scapula and jaw. Movement superiorly. |
Depression*Hint: dePRESSion | Scapula and jaw. Movement inferiorly. |
