The joint where the neck joins the head is a pivotal joint (also known as a pivot joint). This joint allows us to bend our head forward and backward and turn the head to our right or left. In this type of joint, a cylindrical bone rotates within a ring formed by another bone and a ligament. Specifically, this occurs at the atlanto-axial joint between the first cervical vertebra (atlas) and the second cervical vertebra (axis).

• Ball and socket joint: Allows movement in all directions (e.g., shoulder and hip joints).
• Hinge joint: Allows only back and forth movement, similar to the hinges of a door (e.g., elbow and knee joints).
• Saddle joint: Provides stability and flexibility, found at the base of the thumb.
