Examples of a pivot joint include: Proximal radioulnar joint; Distal radioulnar joint; Median atlanto-axial joint; In contrast, spherical joints (or ball and socket joints) such as the hip joint permit rotation and all other directional movement, while pivot joints only permit rotation.
elevation of the scapula at the shoulders (e.g. shrugging shoulders) include: . Levator scapulae muscle; Rhomboid major muscle and Rhomboid minor muscle; Trapezius muscle; elevation of the ribs
Adduction is an anatomical term of motion referring to a movement which brings a part of the anatomy closer to the middle sagittal plane of the body. Upper limb [ edit ]
The proximal radioulnar joint is a synovial pivot joint. [1] It occurs between the circumference of the head of the radius and the ring formed by the radial notch of the ulna and the annular ligament. [2] The interosseous membrane of the forearm and the annular ligament stabilise the joint. [2]
A multiaxial joint, such as the hip joint, allows for three types of movement: anterior-posterior, medial-lateral, and rotational. A multiaxial joint (polyaxial joint or triaxial joint) is a synovial joint that allows for several directions of movement. [9] In the human body, the shoulder and hip joints are multiaxial joints.

A joint or articulation (or articular surface) is the connection made between bones, ossicles, or other hard structures in the body which link an animal's skeletal system into a functional whole. [ 1 ] [ 2 ] [ 3 ] They are constructed to allow for different degrees and types of movement.
The median atlanto-axial joint is sometimes considered a triple joint: [3] one between the posterior surface of the anterior arch of atlas and the front of the odontoid process; one between the anterior surface of the ligament and the back of the odontoid process; The lateral atlantoaxial joint involves the lateral mass of atlas and axis. [4]
The shoulder joint involves articulation between the glenoid cavity of the scapula (shoulder blade) and the head of the upper arm bone and functions as a diarthrosis and multiaxial joint. Due to the very loose joint capsule that gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body.
