Rotation involves a bone or joint moving around its own axis, like turning your head from side to side. Circumduction involves a combination of flexion, extension, abduction, and adduction movements, resulting in a circular motion at the joint, such as the movement of the arm in a windmill fashion.
The air bubble will travel in the direction opposite to the rotation of the bottle. This is because the rotation motion causes the water to move towards the outer edge of the bottle, displacing the air up towards the center where the bubble is released.
The type of joint found between the first and second vertebrae of the neck region, or the backbone, is called the atlantoaxial joint. It allows for rotation and flexion of the neck.
The neck acts as a third-class lever, as the effort (muscle force) is applied between the fulcrum (cervical vertebrae) and the load (head). This allows for a wide range of motion but requires more effort from the muscles.
The force demonstrated when air rushing out of the neck of a balloon causes the balloon to move is an example of Newton's third law of motion, where for every action there is an equal and opposite reaction. As the air rushes out in one direction, it propels the balloon in the opposite direction.
flexion and lateral rotation of the neck
The cervical spine, or neck region of the vertebral column, is capable of the most movement due to its anatomy and structure. It consists of seven vertebrae that allow for a wide range of motion, including flexion, extension, rotation, and lateral bending.
On the lateral side of neck
A plane in the neck.
The joint in your neck is a combination of various types of joints, including ball-and-socket joints in the cervical spine and plane joints between the vertebrae. These joints allow for the range of motion and flexibility needed in the neck.
Sternocleidomastoid and the Scalenes are Synergists, which mean that they work together to provide the same movements (flexion, rotation and lateral flexion of the head and neck)An Antagonist is a muscle that does the opposite movements. In this case, Antagonists of the Scalenes would be your posterior neck muscles, such as:Upper TrapeziusSplenius CapitusSplenius CervicisSemispinalis Capitis, etc
trapezius
The axis is the second cervical vertebra (C2) in the neck region, which forms a joint with the first cervical vertebra (C1) called the atlantoaxial joint. This joint allows for rotation of the head from side to side, giving us a wider range of movement in the neck.
The atlas bone (C1 vertebra) allows you to shake your head because it supports the weight of the skull and allows for a greater range of motion in the neck. It is responsible for nodding, tilting, and shaking the head.
This sounds like something that you read in an exam form or diagnostic report. ?What is being described is either active range of motion in the neck or passive range of motion in the neck. ?Active range of motion meaning how far you can flex or turn you neck yourself, passive range of motion meaning how far can the doctor move your neck. ?Forward flexion meaning how far can your head move forward in degrees as you bring your chin to your chest. ?Extension meaning how far can you bring your head back like you are looking at the ceiling. ?Rotation meaning how far can you turn your head to the right or the left. ?Side ending, lateral bending, or lateral flexion meaning how far could you bend you head to the right or left side, as if you were bringing your ear toward your shoulder.There are different "normal" values for active versus passive. ?And in fact there are different values for active or passive amongst many different textbooks. ?It sounds like "side bending" range of motion is reduced when bending to the right when compared to the left. ?It also sounds like "cervical rotation" is reduced when turning to the left when compared to the right.?Reduced cervical range of motion is an indicator of some kind of neck dysfunction that is probably musculoskeletal. ?What that dysfunction is requires a complete history & examination that may include the addition of special tests like x-rays, MRI, CT, &/or EMG. ?You should seek the advice of your health-care professional to determine what this means in the context of a complete examination. ?From there you can discuss with your health-care professional how best to treat your problem.
Hinge joint: Allows movement in only one plane, like the knee or elbow, creating a bending and straightening action. Ball-and-socket joint: Provides multi-directional movement, allowing rotation, flexion, extension, abduction, and adduction, like the hip and shoulder joints. Pivot joint: Enables rotation around a central axis, like the joint between the atlas and axis vertebrae in the neck.
Rotation in medical terms refers to the movement of a body part around its axis. For example, rotation of the arm occurs when we turn our palm up or down. In anatomy, rotation also refers to the movement of a joint that allows a body part to move in a circular motion.
