Study Notes
Range of Motion Terms
- Abduction involves moving a body part away from the central axis, crucial for limb mobility.
- Adduction is the opposite of abduction, bringing a body part closer to the midline, essential for stabilization.
- Flexion refers to bending a body part, reducing the angle between two segments, important for joint movement.
- Extension is the straightening of a body part, increasing the angle and restoring limb positioning.
- Hyperextension occurs when a body part is excessively straightened beyond its normal range, potentially leading to injury.
- Rotation involves turning a body part around its own axis, such as the head turning side to side, critical for directional movement.
- Circumduction is a circular movement at joints, incorporating flexion, extension, abduction, adduction, and rotation, evident in arm swings.
- Pronation describes the act of turning a body part downward, specifically the palm facing down, relevant in various hand functions.
- Supination is turning a body part upward, particularly with the palm facing up, important for certain grips and actions.
- Opposition enables the thumb to touch the tips of the fingers, a unique human feature allowing grasping and manipulation.
- Inversion involves turning a body part inward, particularly the foot, altering alignment and stability.
- Eversion is the opposite of inversion, turning a body part outward, contributing to balance and mobility.
- Dorsiflexion involves bending the foot backward towards the knee, crucial for activities like walking and running.
- Plantar flexion is the opposite movement, extending the foot away from the knee, important for push-off in walking.
- Radial deviation moves the wrist toward the thumb side, facilitating thumb movement and gripping.
- Ulnar deviation shifts the wrist toward the little finger side, impacting hand positioning and function.
