    Study Notes

    Bone Movement

    Bone movement refers to the various ways in which bones move in relation to each other. There are several types of bone movement, including:

    Rotation

    • Rotational movement occurs when a bone rotates around a fixed axis, such as the rotation of the head on the atlas bone.
    • This type of movement is typically seen in ball-and-socket joints, such as the shoulder and hip joints.

    Extension

    • Extension is a movement that increases the angle between two bones, such as straightening the elbow or knee.
    • It is the opposite of flexion, which decreases the angle between two bones.

    Abduction

    • Abduction is a movement that takes a bone away from the midline of the body, such as raising the arm out to the side.
    • This type of movement is typically seen in joints that allow for lateral movement, such as the shoulder and hip joints.

    Flexion

    • Flexion is a movement that decreases the angle between two bones, such as bending the elbow or knee.
    • It is the opposite of extension, which increases the angle between two bones.

    Adduction

    • Adduction is a movement that brings a bone towards the midline of the body, such as bringing the arm back down to the side.
    • This type of movement is typically seen in joints that allow for lateral movement, such as the shoulder and hip joints.

    Note: These movements can occur in different planes of motion, such as the sagittal, frontal, or transverse plane, depending on the joint and the direction of movement.

    Bone Movement

    • Bone movement refers to the various ways in which bones move in relation to each other.

    Types of Bone Movement

    • Rotational movement: occurs when a bone rotates around a fixed axis, typically seen in ball-and-socket joints, such as the shoulder and hip joints.
    • Extension: increases the angle between two bones, such as straightening the elbow or knee, opposite of flexion.
    • Abduction: takes a bone away from the midline of the body, typically seen in joints allowing lateral movement, such as the shoulder and hip joints.
    • Flexion: decreases the angle between two bones, such as bending the elbow or knee, opposite of extension.
    • Adduction: brings a bone towards the midline of the body, typically seen in joints allowing lateral movement, such as the shoulder and hip joints.

    Movement Planes

    • Bone movements can occur in different planes of motion, including the sagittal, frontal, or transverse plane, depending on the joint and direction of movement.
