Question
Answer
Joint (articulation)   site where two or more bones meet andenable movement  
🗑
Structural classification   bases on how bony regions are separated  
🗑
Fibrous joints   fibrous tissue  
🗑
Cartilaginous joints   cartilage  
🗑
Synovial joints   joint cavity  
🗑
How are Joints Classified   By the type of tissue that binds them together and also by grouped according to the range of movement possible at the junctions betweenbones.  
🗑
Functional classification   degree of movement  
🗑
Synarthrosis   immovable jointsEx. Suture between the bones of the skull  
🗑
Amphiarthrosis   slightly movable jointsEx. Joints between the pubic bones of the pelvis & vertebrae  
🗑
Diarthrosis   freely movable joints  
🗑
Fibrous Joints   Bones united by fibrous tissue - 3 types:a. Syndesmosisb. Suturec. Gomphosis  
🗑
Syndesmosis   Bones bound by interosseous ligament- ampthriarthoric  
🗑
Suture   Between the flat bones of skull only- sutural ligaments- synarthrotic  
🗑
Gomphosis   Formed by union of cone-shaped bony process in a bony socket-synarthrotic  
🗑
Periodontal ligament   root to tooth fastened to the jawbone  
🗑
Cartilaginous joints   Hyaline of fibrocartilage unite bonesTwo Types:a. Synchondrosisb. Symphysis  
🗑
Synchondrosis   Hyaline cartilage untie bones-Temporary- cartilage band- epiphyseal plate-Permantet- between manubrium & 1st rib-Synarthrotic  
🗑
Symphysis   Articular surface covered by thin hyaline and fibrocartilage-Symphysis pubis (pelvis) & intervertebral disks (amphiarthrotic)  
🗑
Synovial Joints   Most jointsAllow free movement - diarthroticConsist of:- Articular cartilage- Joint cavity or capsule - Synovial membrane -secretes synovial fluid  
🗑
General Structure of synovial joint:   - Articular cartilage- Tubular joint capsule- Ligaments- Synovial membrane- Synovial fluid- Menisci- Burase  
🗑
Articular cartilage   Hyaline cartilage at ends of long bones  
🗑
Tubular joint capsule   - 2 layers of dense connective tissue- Holds together bones of synovial joint- Its fibers attach to periosteum  
🗑
Ligaments   - tough collagenous fibers - reinforce joint capsule - bind articular ends- May be inside fibrous layer of capsule or outside- Prevent excessive movement at the joint- Relatively inelastic  
🗑
Synovial membrane   - inner layer of joint capsule - loose connective tissue- Covers all surfaces within joint capsule except articular cartilage- Surrounds synovial cavity, closes sac  
🗑
Synovial fluid   - produced by synovial membrane- lubricates smooth cartilaginous surfaces within joint- Supplies articular cartilage with nutrients  
🗑
Menisci   - Between articular surfaces of some joints- Help cushion and distribute body weight (knee)  
🗑
Bursae   - Sac filled with synovial fluid- Patella of the knee & olecranon process of the elbow- Cushion - Aid in movement of tendons that glide over the bony portion of the joint  
🗑
Rheumatoid arthritis   - autoimmune disease- Affects joints & surrounding muscle, tendons, ligaments, & blood vessels- 10% total disability because of fibrous & bony ankylosis- Affects women 3 times more often then men  
🗑
The 4 Stages of Rhemuatoid Arthritis   Peak onset- 35 to 50 years old1. Synovitis – from congestion & edema2. Pannus – thickened layers & tissues invades joint capsule & bone3. Fibrous ankylosis – scar formation4. Calcification – bony ankylosis – total immobility  
🗑
Osteoarthritis   - wear & tear, obesity, inactivity- Common in hips & knees- Deterioration of joint cartilage  
🗑
Gouty arthritis or gout   high levels of uric acid  
🗑
Scleroderma   skin hardens and thickens  
🗑
Gliding joints   Bone surfaces slide over one another. (Joints in wrist & ankle)  
🗑
Hinge joints   allows movement in one direction changing the angle of the bones at the joint (elbow  
🗑
Pivot joint   allows rotation around length of bones.(Joints between the 1st & 2nd cervical vertebrae)  
🗑
Condyloid   allows movement in 2 directions.(joint b.t wrist & the bones of the forearm)  
🗑
Ball and Sockect   allows movement in many directions around a central point (hip & shoulder)  
🗑
Saddle joint   between the trapezuim and the metacarpal #1  
🗑
flexion   a decreas in the angle between 2 bonesex.- bending the fingers to close the hand  
🗑
Extension   Straightening motion that increase the angle between bonesex.- straightening the fingers to open the hand  
🗑
Hyperextension   excess extension of the parts at a joint, beyond the anatomical positionex.- bend the hand back  
🗑
Dorsiflexion   bending the foot at the ankle toward the shin ex.- bending the foot upward  
🗑
Plantar flexioin   bending the foot at the ankle toward the sole ex.- bending the foot downward  
🗑
Abduction   moving a part away from the midline  
🗑
Adduction   moving a part toward the midline  
🗑
Supination   turning the hand so the palm is upward  
🗑
Pronation   turning the hand so the palm is downward  
🗑
Eversion   turning the foot so the sole face laterally  
🗑
Inversion   turning the foot so the sole faces medially  
🗑
Protraction   moving a part fowardex.- thrusting the chin foward  
🗑
Retraction   moving a part backwardex.- pulling the chin backward  
🗑
Elevation   raising a partex.- shurring the shoulders  
🗑
Depression   lowering a partex.- drooping the shoulders  
🗑
