Anatomy and Physiology 1 Lab 7 - Articulations

Amphiarthrosis

Slightly mobile joint

Articulation

Joint of the body

Biaxial joint

Type of diarthrosis; a joint that allows for movements within two planes (two axes)

Cartilaginous joint

Joint at which the bones are united by hyaline cartilage (synchondrosis) or fibrocartilage (symphysis)

Diarthrosis

Freely mobile joint

Fibrous joint

Joint where the articulating areas of the adjacent bones are connected by fibrous connective tissue (Syndesmoses)

Joint

Site at which two or more bones or bone and cartilage come together (articulate)

Joint cavity

Space enclosed by the articular capsule of a synovial joint that is filled with synovial fluid and contains the articulating surfaces of the adjacent bones

Multiaxial joint

Type of diarthrosis; a joint that allows for movements within three planes (three axes)

Synarthrosis

Immobile or nearly immobile joint

Synovial joint

Joint at which the articulating surfaces of the bones are located within a joint cavity formed by an articular capsule

Uniaxial joint

Type of diarthrosis; joint that allows for motion within only one plane (one axis)

Synovial Joints - Planar

Gliding motion between carpals and tarsals

Synovial Joints - Hinge

Unidirectional joint seen at knee and elbow

Synovial Joints - Pivot

Rotation along an axis seen between C1 and C2, and between radius and ulna

Synovial Joints - Saddle

Looks like a saddle; trapezium of the carpal-metacarpal joint, seen in the thumb

Synovial Joints - Condyloid

Ovoid (3 dimentional egg shaped) surface that articulates with a bone that fits in the ovoid surface and produces movement along two planes, metacarpal-phalangeal joint

Synovial Joints - Ball and socket

Ball in socket, seen in shoulder and hips

Fibrous joints - Sutures

Joint composed of tiny ligaments between cranial bones

Fibrous joints - Syndesmosis

Joint between two bones united by strong membrane or ligament

Fibrous joints - Gomphosis

Periodontal ligaments supporting a tooth in a bony socket

Cartilaginous - Synchondrosis

Epiphyseal plate (growth plate, between the ends (epiphysis) and the shaft (metaphysis) of long bones), and ribs to sternum

Cartilaginous - Symphysis

Between pubic bones, and intervertebral discs
