The only bone that the patella, or kneecap, articulates with is the femur, at the patellofemoral joint. The patella is a sesamoid bone, meaning it is fully embedded within a tendon. The patellar ligament joins the patella to the tibial tuberosity (but not the fibula).

Bruxism, or involuntary tooth grinding, can cause inflammation and damage in the temporomandibular joint, which is the articulation between the condyle of the mandible and the temporal bone.

The xiphisternal joint is between the xiphoid process and the body of the sternum. The intermetacarpal joints are formed between the metacarpal bones of the hand, and the pisotriquetral joint is between the pisiform and triquetrum of the wrist.

Movement along a sagittal plane that decreases the angle between bones is flexion. This is in contrast to extension, which is movement along a sagittal plane that increases the angle between bones. Adduction is movement that pulls a structure toward the midline of the body, while abduction moves a structure away from midline.

Bursae are synovial fluid sac between bones and overlying tissues. They provide a cushion between the bone and tendons or musculature around them, allowing for reduced friction and painless movement.

A tendon is a connective tissue point of attachment of muscle to bone, while a ligament is a connective tissue attachment from bone to bone. A capsule is a fibrous, fluid filled structure surrounding a synovial joint.

Gomphosis joints are fibrous joints that attach the root of the tooth to the bony socket of the mandible or maxilla.

Both the tibio-fibular joint and the joint between the radius and ulna are syndesmoses, while the joints between the bones of the skull are sutures.

The majority of joints of the human body are synovial joints. These joints are diarthrotic and include a synovial joint capsule that allows for greater freedom of movement. Examples include the fingers and the elbows, the knees, the temporomandibular joint, and the hips.

Fibrous and cartilagenous joints, all of which are either synarthrotic or amphiarthrotic, are relatively less common.

The intervertebral disc articulate with the vertebrae via cartilaginous symphysis joints. These joints are amphiarthrotic, meaning that they allow for slight mobility.

Synovial joints are all diarthrotic and characterized by a flexible joint capsule filled with synovial fluid. Synarthrotic joints have no movement - examples include the skull bones and the joints of the teeth to the jaw.

The structural classification of joints divides them according to the form of tissue that connects bones to each other. The three structural divisions of joints are fibrous, cartilaginous, and synovial. In contrast, synarthrosis, amphiarthrosis, and diarthrosis are all classifications of a joint's movement.

Condyloid, gliding, and hinge joints are all types of synovial joints, while sutures, syndesmosis, and gomphosis are all types of fibrous joints.

Circumduction is movement that produces a circular motion wth the distal end of a body part. True circumduction allows for a 360 degree range of movement. Of the joints listed, the only one capable of circumduction is the shoulder.

Condyloid joints are a form of synovial joint in which a condyle rests in an ovoid cavity. Of the joints listed, the only condyloid joint is the metacarpophalangeal joints (the joint of the most proximal knuckle).

The acromioclavicular joint is a plane joint, while the glenohumeral and humeroradial joints are both ball and socket joints.
