Joints can also be classified based on their anatomy or on their biomechanical properties. According to the anatomic classification, joints are subdivided into simple and compound, depending on the number of bones involved, and into complex and combination joints: [19] Simple joint: two articulation surfaces (e.g. shoulder joint, hip joint)
Examples of ginglymoid joints are the interphalangeal joints of the hand and those of the foot and the joint between the humerus and ulna. The knee joints and ankle joints are less typical, as they allow a slight degree of rotation or side-to-side movement in certain positions of the limb. The knee is the largest hinge joint in the human body.
A joint, or articulation is the region where adjacent bones contact each other, for example the elbow, shoulder, or costovertebral joint. Terms that refer to joints include: articular process, referring to a projection that contacts an adjacent bone. suture, referring to an articulation between cranial bones.
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: [2] the wrist-joint; metacarpophalangeal joints; metatarsophalangeal joints; atlanto-occipital joints; These are also called ellipsoid joints. The oval-shaped condyle of one bone fits into the elliptical cavity of the other bone. These joints allow biaxial movements [3] — i.e., forward and backward, or from side to side, but ...

Examples of this form of articulation are found in the hip, where the round head of the femur (ball) rests in the cup-like acetabulum (socket) of the pelvis; and in the shoulder joint, where the rounded upper extremity of the humerus (ball) rests in the cup-like glenoid fossa (socket) of the shoulder blade.

In anatomy, a joint capsule or articular capsule is an envelope surrounding a synovial joint. [1] ... and thus entirely surrounds the articulation.
