Anatomical terms, planes, and movements
Question | Answer |
---|---|
medial | toward the midline of the body |
lateral | away from the midline of the body |
proximal | nearest to a reference point |
distal | farthest from a reference point |
inferior | below |
superior | above |
cranial or cephalad | toward the head |
caudal or caudad | toward the tailbone |
anterior | toward the front |
posterior | toward the back |
coronal plane or frontal plane | vertical flat surface running from side to side; cutting the body into anterior and posterior sides |
sagittal plane or lateral plane | vertical flat surface running from front to back; cutting the body into right and left sides |
axial plane or transverse plane | a horizontal plane dividing the body into upper and lower parts |
flexion | decreases the angle between 2 bones |
extension | increases the angle between 2 bones |
hyperextension | increase the angle between 2 bones beyond the normal range of motion |
abduction | describes movements of the limbs; limb moves away from the mid line of the body |
adduction | describes movements of the limbs; limb moves toward the mid line of the body |
rotation | occurs when a bone turns on its axis toward or away from the mid line of the body |
circumduction | ability of a limb to move in a circular path around an axis. The proximal portion of the limb remains stationary, while the distal portion moves in a circle |
supination | movement of the radius and ulna anterior or superior; act of turning the palm upward |
pronation | movement of the radius and ulna posterior and inferior; act of turning the palm downward |
plantar flexion | extends the foot, with the toes pointing down |
dorsiflexion | flexes the foot, bringing the toes up toward the lower leg |
inversion | turns the sole of the foot inward |
eversion | turns the sole of the foot outward |
protraction | movement of a body part forward in a transverse plane (shoulders, jaw) |
retraction | movement of a body part backward in a transverse plane |
elevation | movement of a body part upward in a frontal plane |
depression | movement of a body part downward in a frontal plane |
opposition | movement of the thumb to touch each finger |
