Articulation joints Flashcards Set

Articulation

The point where two bones meet/connect; can allow movement or be immovable.

Bursae

A pad made up of synovial membrane that contains synovial fluid, cushioning and lubricating joints.

Tendon Sheath

A protective, tube-like structure surrounding a tendon, facilitating smooth gliding over other tissues.

Meniscus

A C-shaped piece of tough cartilage that acts as a shock absorber between bones.

Fat Pads

Tissue around joints that helps cushion and support.

Fibrous Joints

Immovable joints connected by dense fibrous connective tissue, with no joint cavity; e.g., skull sutures.

Cartilaginous Joints

Joints connected by cartilage with no joint cavity; e.g., intervertebral discs.

Bony Fusion

Where bone to bone fuse together with no joint cavity; e.g., sacrum and coccyx.

Synovial Joints

Joints allowing free movement, surrounded by a fibrous capsule with synovial lining; e.g., elbow and hip.

Synarthrosis

A type of joint where no movement is allowed; e.g., skull sutures.

Amphiarthrosis

A joint allowing slight movement; e.g., pubic symphysis.

Diarthrosis

A joint allowing variable movement; e.g., elbow and shoulder joints.

Suture

A synarthrosis fibrous joint found in the skull, described as 'sewing together'.

Syndesmosis

An amphiarthrosis fibrous joint, connecting long bones of the lower arm/leg.

Gomphosis

A synarthrosis fibrous joint that connects teeth.

Synchondrosis

A synarthrosis cartilaginous joint made of hyaline cartilage; e.g., epiphyseal plates.

Symphysis

An amphiarthrosis cartilaginous joint made of fibrocartilage; e.g., intervertebral discs.

Synostosis

A synarthrosis bony fusion joint where bone is joined to bone.

Diarthrosis Nonaxial

A synovial joint with no specific plane of movement; e.g., gliding movements. example intercarpal and intertarsal joints,

Diarthrosis Uniaxial

A synovial joint with one plane of movement; e.g., hinge and pivot joints. example elbow joint,

Diarthrosis Biaxial

A synovial joint with two planes of movement; e.g., saddle and condyloid joints. example knuckle joint

Diarthrosis Triaxial

A synovial joint with three planes of movement; e.g., ball and socket joints. example, the shoulder and hip joints
