Articulations - Joints

Articulations

Where two bones meet

Synarthrotic joint

No movement

Diarthrotic joint

freely moveable

Amphiarthrotic

little movement

Fibrous joints are held together by 

collagenous fibers

gomphosis joints are found in ____

teeth

Synchondroses

hyaline ( hard ) cartilage connects bone. Many are temporary joints ( epiphyseal growth plate)

Symphysis

A cartilaginous pad. joint covered by hyaline cartilage. Absorbs shock. In the pubic symphysis. Slightly flexible

Articular Cartilage

Ends of bone that are covered with a thin layer of hyaline cartilage

Articular cartilage get rejuvenated using synovial fluid, because they are ______

avascular

the outer layer of the joint capsule

connects ligaments to both bones, completely surrounds joint to prevent excessive movements.

the inner layer of the joint capsule

the vascular membrane of loose CT, synovial membrane lines the inside. Covers joint surfaces not covered by cartilage.

Synovial membrane

cover all surfaces within joint capsule. secretes synovial fluid inside the synovial cavity

Synovial fluid

lubricates and moistens surfaces of joints.

Bursae

fluid filled sacs in synovial joints that cushion, and aid in movement of tendons, ligaments and muscles

Meniscus

Discs of fibrocartilage between articulations that divide joints into two components

Ligaments

connect bone to bone

Tendons

attach muscle to bone

Osteoarthritic

Cartilage on surface of joints wears down. causes pain, stiffness, and swelling.

Rheumatoid Arthritis

Causes inflammation of joint cased by immune attack on synovial tissue.
