In animal anatomy, a pivot joint (trochoid joint, rotary joint or lateral ginglymus) is a type of synovial joint whose movement axis is parallel to the long axis of the proximal bone, which typically has a convex articular surface.
Humeroradial joint: head of the radius: capitulum of the humerus: Is a ball-and-socket joint. Superior radioulnar joint: head of the radius: radial notch of the ulna: In any position of flexion or extension, the radius, carrying the hand with it, can be rotated in it. This movement includespronation and supination.
The musculoskeletal system provides form, support, stability, and movement to the body. The human musculoskeletal system is made up of the bones of the skeleton , muscles , cartilage , [ 1 ] tendons , ligaments , joints , and other connective tissue that supports and binds tissues and organs together.
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.

Examples include a movement of the knee, where the lower leg changes angle compared to the femur, or movements of the ankle. [2] The study of movement in the human body is known as kinesiology. [4] A categoric list of movements and the muscles involved can be found at list of movements of the human body.
The most common form of arthritis, osteoarthritis (also known as degenerative joint disease), occurs following trauma to the joint, following an infection of the joint or simply as a result of aging and the deterioration of articular cartilage. Furthermore, there is emerging evidence that abnormal anatomy may contribute to early development of ...
Rotational. During the opening of mandible, rotation is the movement at the start of its movement, this occurs in the lower temporomandibular joint compartment. As mandible is being depressed, condyle is tightly bounded to the articular disc by medial and collateral ligaments, hence only allowing rotational movements. [7]
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
