Anatomy of Joints Quiz

Joints where bones are connected by fibrocartilage and do not ossify with age. They have limited movement.

Freely movable joints with a joint cavity, hyaline cartilage covering bones, and a synovial membrane that produces lubricating fluid supporting movement.

Cartilaginous joints are classified into primary (synchondroses) and secondary (symphyses). Primary are hyaline cartilage, limited movement. Secondary are fibrocartilage, slightly more movement.

Synovial joints have articular cartilage, a joint cavity, a fibrous capsule, synovial membrane, synovial fluid, and sometimes menisci, discs, or labra.

The inferior tibiofibular joint is a secondary cartilaginous joint.

Joints are the articulations between two or more bones.

Fibrous joints are connected by fibrous tissue, allowing little to no movement.

Fibrous joints include sutures (skull bones), gomphoses (teeth), and syndesmoses (ligaments).

Cartilaginous joints are connected by cartilage, allowing little to no movement.

Synovial joints are characterized by a joint cavity and synovial fluid for movement.

Nerve supply to a joint innervates the joint itself, surrounding tissues, the muscles acting on the joint and the skin overlying the muscles.

Cartilaginous joints include primary (e.g., epiphyseal plate) and secondary (e.g., 1st sternocostal joint).

Factors affecting joint stability include the shape of the articulating surfaces, ligaments, muscles, and other factors.

A synovial joint with two articulating bones.

A synovial joint with more than two articulating bones.

A synovial joint with intra-articular disc or meniscus.

A synovial joint allowing movement in one axis.

A uniaxial joint that allows flexion and extension.

Uni-axial joint that allows rotation.

A synovial joint that permits movement in two axes.

A synovial joint that permits movement in more than two axes.

The shoulder joint is a ball and socket synovial joint. This allows for a wide range of movements, including flexion, extension, abduction, adduction, rotation, and circumduction.

Plane synovial joints have flat articular surfaces allowing for gliding movement in any direction. Examples include intercarpal and intertarsal joints.

Hinge synovial joints allow movement in one plane, like a door hinge. Examples include the elbow and knee joints.

Pivot synovial joints have a central axis allowing for rotation around that axis. Examples include the joint between the atlas and axis vertebrae.

A ball and socket joint has a round head of bone fitting into a cup-like socket. This allows for movement in multiple planes, including flexion, extension, abduction, adduction, rotation, and circumduction. Examples include the shoulder and hip joints.
