HBS 1.2.5-1.2.6 Review

What is circumduction?

• A linear movement of a limb in one direction.

• A circular movement of a limb that involves flexion, extension, abduction, and adduction.

• A movement that only involves rotation around a joint.

• A movement that only involves straightening a limb.

What is the role of ligaments in joints?

• Ligaments connect muscles to bones, allowing movement.

• Ligaments connect bones to other bones, providing stability to joints.

• Ligaments are responsible for producing synovial fluid in joints.

• Ligaments cushion the joints and absorb shock during movement.

What is an example of a saddle joint?

• Joint at the base of the thumb

• Elbow joint

• Knee joint

• Shoulder joint

What is the anatomical position?

• A standard position of the body where it stands upright, facing forward, with arms at the sides and palms facing forward.

• A position where the body is lying down on its back with arms crossed over the chest.

• A position where the body is seated with legs crossed and hands on the knees.

• A position where the body is bent forward at the waist with arms hanging down.

What are the types of synovial joints?

• Hinge, ball-and-socket, pivot, saddle, condyloid, and plane joints.

• Hinge, fixed, sliding, and ball-and-socket joints.

• Hinge, ball-and-socket, and immovable joints.

• Saddle, pivot, and elastic joints.

What are fibrous joints?

• Joints that are movable and connected by cartilage.

• Joints that are immovable, connected by dense connective tissue.

• Joints that allow for a wide range of motion and are connected by ligaments.

• Joints that are partially movable and connected by synovial fluid.

What is lateral rotation?

• Lateral rotation is the movement of a body part away from the midline of the body.

• Lateral rotation is the movement of a body part towards the midline of the body.

• Lateral rotation is the circular movement of a body part around a fixed point.

• Lateral rotation is the upward movement of a body part in relation to the body.

What is the range of motion for shoulder extension?

• Shoulder extension is the movement of the arm backward, increasing the angle between the arm and the body.

• Shoulder extension is the movement of the arm forward, decreasing the angle between the arm and the body.

• Shoulder extension is the movement of the arm sideways, maintaining the angle between the arm and the body.

• Shoulder extension is the movement of the arm in a circular motion around the shoulder joint.

What is the difference between immovable and freely movable joints?

• Immovable joints allow a wide range of motion, while freely movable joints do not.

• Immovable joints do not allow movement (e.g., sutures in the skull), while freely movable joints allow a wide range of motion (e.g., knee, elbow).

• Immovable joints are found only in the arms, while freely movable joints are found in the legs.

• Immovable joints are flexible, while freely movable joints are rigid.

What is eversion?

• Eversion is the movement of the sole of the foot outward, away from the midline.

• Eversion is the movement of the sole of the foot inward, towards the midline.

• Eversion refers to the bending of the foot at the ankle joint.

• Eversion is the rotation of the foot in a circular motion.
