Kinesiology Terms
Location and Movement terminology
Term | Definition |
---|---|
Kinesiology | the study of motion |
Anatomic position | the person is standing erect, facing forward, with the arms at the sides, the palms facing forward, and the fingers and toes extended |
Anterior | farther to the front |
Posterior | farther to the back |
Ventral | The soft belly surface of a body part; sometimes used for anterior |
Dorsal | The harder surface of a body part; sometimes used for posterior |
Medial | Closer to the imaginary midline that divides the body |
Lateral | Farther from the imaginary midline that divides the body |
Superior | Above (toward the head) |
Inferior | Means below (away from the head) |
Proximal | Closer to the axial body |
Distal | Farther from the axial body |
Superficial | Closer to the surface of the body |
Deep | farther from the surface of the body (i.e., more internal) |
Radial | May be used in place of lateral for the forearm and hand |
Ulnar | May be used in place of medial for the forearm and hand |
Tibial | May be used in place of medial for the leg and foot |
Fibular | May be used in place of lateral for the leg and foot |
Palmar | May be used in place of the term anterior for the hand |
Plantar | The undersurface of the foot that is on the ground |
Cranial | Toward the head |
Caudal | Toward the tail |
Plane | Flat surfaces that cut through and can be used to map three-dimensional space |
Cardinal Planes | The three cardinal planes are sagittal, frontal, and transverse |
Sagittal plane | divides the body into left and right portions |
Frontal plane | divides the body into front and back (anterior and posterior) portions |
Transverse plane | divides the body into upper and lower (superior and inferior or proximal and distal) portions |
Oblique plane | Any plane that is not perfectly sagittal, frontal, or transverse |
Vertical | Movements in the Sagittal & Frontal planes are: |
Horizontal | Movement in the transverse plane is: |
Perpendicular | The orientation of an AXIS for movement within a plane is always: |
Joint Actions | Movement terms that describe cardinal plane motions of a body part |
Flexion | generally an anterior movement of a body part within the sagittal plane |
Extension | generally a posterior movement within the sagittal plane |
Abduction | generally a lateral movement within the frontal plane that is away from the imaginary midline of the body |
Adduction | a medial movement toward the midline |
Right lateral flexion | a side-bending movement of the head, neck, and/or trunk toward the right within the frontal plane |
Left lateral flexion | a side-bending movement of the head, neck, and/or trunk toward the left within the frontal plane |
Lateral rotation | a movement within the transverse plane in which the anterior surface of the body part moves to face more laterally |
Medial rotation | moves the anterior surface to face more medially (toward the midline) |
Right rotation | movement within the transverse plane in which the anterior surface of the body part moves to face more to the right |
Left rotation | movement within the transverse plane in which the anterior surface of the body part moves to face more to the left |
Ipsilateral | Rotation to the same side |
Contralateral | Rotation to the opposite side |
Elevation | a movement wherein the body part moves superiorly |
Depression | occurs when the body part moves inferiorly |
Protraction | a movement wherein the body part moves anteriorly |
Retraction | a posterior movement of the body part |
Pronation of the forearm | Results in the posterior surface of the radius facing anteriorly |
Supination of the forearm | Results in the anterior surface of the radius facing anteriorly |
Pronation of the foot | Movement of the foot at the subtalar that is made up primarily of eversion |
Supination of the foot | Movement of the foot at the subtalar that is made up primarily of inversion |
Inversion | When the plantar surface of the foot faces toward the midline of the body |
Eversion | When the plantar surface of the foot is turned outward away from the midline of the body |
Dorsiflexion | When the foot moves superiorly |
Plantarflexion | When the foot moves inferiorly |
Opposition | Movement of the thumb when its pad meets the pad of another finger |
Reposition | Movement of the thumb returning back from opposition |
Upward Rotation | Movement of the scapula when its glenoid fossa is moved to face more superiorly |
Downward Rotation | Movement of the scapula when its glenoid fossa is moved to face more inferiorly |
Horizontal Flexion | Movement of the arm or thigh in which it begins in a horizontal position and then moves toward the midline of the body; AKA horizontal adduction |
Horizontal Extension | Movement of the arm or thigh in which it begins in a horizontal position and then moves away from the midline of the body, AKA horizontal abduction |
Circumduction | Not a joint action; it is a sequence of four joint actions performed one after the other in a circular fashion |
