General Infromation About Joint

Question 1

Classification of joint

Answer 1

Simple joint: type of synovial joint and two bone are involved
Composite joint : type synovial joint and more then two points

Question 2

Structure classification of joint

Answer 2

Fibrous : ( synarthrosis) little/ no mobility
Cartilage: ( amphiarthrosis) slight mobility
Synoxail ( diathrosis) freely movable

Question 3

Cartilage and the types

Answer 3

Strong flexible connections tissue that protects your joint and bones
Types ;
Hyline: at the end of bone , btw your ribs, in your nasal passages
Elastic : wall of the external ear , your larynx
Fibrocartilage: btw vertebrae, meniscus in your knee, support muscles tendons ligaments

Question 4

Fibrous joint

Answer 4

Where bone are bound by thought
Syndesmosis: btw parallel bones like radius and ulna , tibia and fibula
Sutures: is in bet the skull
Gomphosis: btw lower and upper jaw

Question 5

Symphsis

Answer 5

fibrocartilaginous fusion between two bones

Question 6

Sybovial joint

Answer 6

1. Articular cartilage: minimsing friction upon joint movement and absorbing shock
2. Articular capsule : fibrous outer layer ( it protects external influences and limit the excessive movement of the joint) synovial inner layer ( is responsible for producing and secreting synovial fluid )
3. Joint cavity: space btw joint face form by the joint capsule that envelopes the joint
4. Reinforcing ligaments

Question 7

Factional classification

Answer 7

Uninxed=more back and forth along single axis
Hinge joint→axis→ transverse (flexion and extension) ankle joint elbow knee joint
Pivot joint →axis→alongtudinal ( rotation) prox and dist radiolnar joint
Biaxiac= move about two distinct axis
Ellipsoidal joint →axis →transverse & A—p ( flex & extension +abd& add) wrist joint mphgeal joint mcarphgeal joint
Saddle joint →transverse $ AP( flex$ext+Abd$add)
Multiaxiac = mover through all three axes sternoclavicar joint fist carpometacarpal joint
Ball and socket joint= axis →transverses a-p$ longiturdal ( flex $ ext+ add $ abd+ rotation) head of fumes shoulder joint hip joint
