Anatomical Terms of Bodily Movements Flashcards
What is Flexion?
Flexion is a movement that occurs in the sagittal plane in which the angle between articulating segments decreases.
What is Extension?
Extension is a movement that occurs in the sagittal plane in which the angle between articulating segments increases.
What is Hyperextension?
Hyperextension occurs when a movement increases beyond the anatomical position and can only occur in certain joints without leading to injury.
What is Abduction?
Abduction occurs in the frontal plane and involves taking a body segment away from the midline.
What is Adduction?
Adduction occurs in the frontal plane and involves moving a body segment towards the midline.
What is Rotation?
Rotation occurs in the transverse plane and can be classified as either lateral rotation (rotation away from the midline) or internal rotation (rotation towards the midline).
What is Plantarflexion?
Plantarflexion occurs at the ankle joint when the foot moves away from the lower leg in the sagittal plane.
What is Dorsiflexion?
Dorsiflexion occurs at the ankle joint when the foot moves towards the lower leg in the sagittal plane.
What is Inversion?
Inversion is when the sole of the foot moves inwards in the frontal plane.
What is Eversion?
Eversion is when the sole of the foot moves outwards in the frontal plane.
What is Supination?
Supination occurs when the forearm or ankle is rotated laterally in the transverse plane.
What is Pronation?
Pronation occurs when the forearm or ankle is rotated medially in the transverse plane.
What is Elevation?
Elevation is a structure moving in a superior or upward motion.
What is Depression?
Depression is a structure moving in an inferior or downward motion.
What is Protraction?
Protraction describes a movement anteriorly or towards the front of the body.
What is Retraction?
Retraction describes a movement posteriorly or towards the back of the body.
What is Lateral Flexion?
Lateral Flexion refers to sideways bending of the vertebral column in the frontal plane.
What is Tilt?
Tilt is a term used to describe certain movements of the head, scapula, and pelvis.
