Neck lateral rotation occurs in the transverse plane of motion. This movement involves rotating the head to the left or right around the central axis of the neck.
Rotation involves, Rotation of the head, neck and lower limb and circumduction, abduction is the angular movements: abduction, adduction and circumduction of the upper limb at the shoulder
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
Tilting your head to bring your right ear toward your right shoulder involves lateral flexion of the cervical spine. This movement primarily engages the muscles on the opposite side of the neck, while the muscles on the side of the tilt contract to stabilize the motion. Additionally, there may be slight rotation of the cervical vertebrae as the head tilts.
Some effective Chinese neck stretches to alleviate neck pain and improve flexibility include the "Neck Rotation" stretch, the "Neck Tilt" stretch, and the "Neck Extension" stretch. These stretches can help release tension in the neck muscles and increase range of motion.
A plane in the neck.
The rotation of the neck is referred to as cervical rotation. This movement involves turning the head to the left or right around the neck's axis, primarily facilitated by the cervical vertebrae and associated muscles. Cervical rotation is essential for various activities, including looking around and maintaining balance.
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.
The closed pack position for the neck, specifically the cervical spine, is typically when the neck is in extension and rotation, often with slight lateral flexion. In this position, the intervertebral joints are maximally congruent, and the surrounding ligaments and muscles are taut, providing stability. This position is important in assessing joint integrity and can influence treatment strategies in physical therapy and rehabilitation.
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.
