ANATOMICAL MOVEMENT Flashcards
(20 cards)
A movement at a joint that reduces the angle between connected body parts.
Example: Bending the arm at the elbow.
Flexion
A movement at a joint that straightens the joint and increases the angle between connected body parts.
Example: Straightening the arm at the elbow.
Extension
Moving a body part away from the body’s midline.
Example: Raising your arm out to the side.
Abduction
Moving a body part toward the body’s midline.
Example: Lowering your raised arm back down to your side.
Adduction
Rotating a body part toward the midline of the body.
Example: Turning the shoulder or thigh inward.
Medial rotation
Rotating a body part away from the midline of the body.
Example: Turning the shoulder or thigh outward.
Lateral rotation
A movement that involves turning a body part around its central axis.
There are two types:
Medial Rotation (Internal Rotation): Rotating toward the body’s midline.
Lateral Rotation (External Rotation): Rotating away from the body’s midline.
Rotation
is an anatomical movement of the forearm and hand. Key points:
It involves turning the forearm and hand so that the palm faces upward or forward.
is essential for tasks like turning a doorknob or holding a cup.
Supination
is an anatomical movement of the forearm and hand. Key points:
It involves turning the forearm and hand so that the palm faces downward or backward.
Is important for activities like typing on a keyboard or performing push-ups.
Pronation
Is an anatomical movement. Key points:
Involves lifting a body part or structure upward.
It’s often used in the context of the shoulder girdle and involves raising the shoulders toward the head.
Can be seen in actions like shrugging the shoulders or lifting the scapula.
Elevation
It involves moving a body part in a downward direction.
Often used in reference to the movement of the shoulders or away from the head.
Examples include relaxing the shoulders after a shrug or lowering the jaw.
Depression
It involves flexing the ankle so that the foot moves upward toward the shin.
is used when you lift your toes toward your shin, like when you walk on your heels.
Dorsiflexion
It involves pointing the foot downward, away from the shin.
is used when you point your toes, like when standing on tiptoes or pushing the gas pedal in a car.
Plantarflexion
It involves turning the sole of the foot inward, toward the midline of the body.
Is important for tasks like balancing on the edges of your feet.
Inversion
It involves turning the sole of the foot outward, away from the midline of the body.
Is important for actions like turning your foot outward or walking on the outer edge of your foot.
Eversion
- It involves bringing the tip of the thumb in contact with the tips of the other fingers.
- Enables precision gripping and fine motor skills.
- This movement allows the thumb to touch each of the four fingers, which is a unique and important function for tasks like grasping small objects.
Opposition
Is the opposite movement of opposition, primarily involving the thumb.
- It involves moving the thumb away from the other fingers, returning it to its original or resting position.
- This movement is the reverse of opposition, where the thumb touches the tips of the other fingers.
- Repositioning the thumb is a basic action in resetting the hand to its natural, relaxed state after performing tasks that require precision gripping or fine motor skills.
Reposition
Is a complex anatomical movement at a joint. Key points:
- It involves a combination of flexion, extension, abduction, and adduction, creating a circular or conical motion at the joint.
- A common example is the movement of the arm at the shoulder joint, where the arm moves in a circular pattern.
Allows for a wide range of motion and is used in activities like drawing circles with your arm.
Circumduction
Is an anatomical movement related to the shoulders and jaw. Key points:
- In the context of the shoulders, it involves moving the shoulder blades forward, away from the spine.
- In the context of the jaw, it refers to pushing the jaw forward.
Is essential for actions like pushing or reaching forward with your shoulders or jutting your jaw out.
Protraction
Is an anatomical movement related to the shoulders and jaw. Key points:
- In the context of the shoulders, it involves moving the shoulder blades backward, toward the spine.
- In the context of the jaw, it refers to pulling the jaw backward.
- s important for actions like pulling your shoulders back or retracting the jaw to its normal position.
