FIBROUS JOINTS

Articulating surfaces of bones are joined by connective tissue. Very little movement is posible

SyndesmosesSuturesGomphoses

SYNDESMOSIS

Two bones bound by ligament only

Most movable of fibrous joint

Interosseus membranes unite radius to ulna and tibia to fibula

fibrous joint in which a conical process is inserted into a socket-like portion.

CARTILIGAGINOUS JOINTS

These are of two types oPrimaryoSecondary

PRIMARY CARTILIGINOUS JOINT

Bones are joined by hyaline cartilage

No movement is possible

PRIMARY CARTILIGINOUS JOINT

First rib attachment to sternumUnion between epiphysis and diaphysis

SECONDARY CARTILIGINOUS JOINT

2 bones joined by fibrocartilagepubic symphysis and intervertebral discsOnly slight amount of movement is possible

STABILITY OF JOINTS

Stability depends on 3 main factors

Shape, size and arrangement of articular surfaces

Associated ligaments

Muscle tone

LIGAMENTS

Fibrous ligaments prevent excessive movement in a joint , but if stress is continued for an excessively long period ,then ligaments will stretch

ARTHRITIS

Arthritis is a broad term for pain and inflammation

Osteoarthritis results from years of joint weararticular cartilage softens and degenerates

accompanied by crackling sounds called crepitus
