Chpt 8 Flashcards
Joints
Type of joints: structural
Fibrous
Cartilaginous
Synovial
Type of joint: function
Synarthrotic-immovable
Amphiarthrotic-slightly movable
Diarthrotic-freely movable
Fibrous joint(type of tissue and the types)
Dense connective tissue
- syndesmosis
- suture
- gomphosis
Syndesmosis
Bundle of connective tissue, amphiarthrotic
Suture(location and function)
Between flat bones of skull
Synarthrotic(immovable)
Gomphosis
Cone shape bone process in a socket in jawbone
-synarthrotic(immovable)
Cartilaginous joints definition
And 2 types
Hyaline or fibro cartilage
Synchondrosis and symphysis
Synchondrosis
Bonds hyaline cartilage unit bones Between manubrium(synarthrotic)
Symphysis
Pad of fibrocartilage
Amphiarthrotic
Intervertenbral discs
Synovial joints
Diarthrotic
Articular cartilage covers ends of bones
6 synovial joints
Bal and socket Candylar Plane Hinge Pivot Saddle
Ball and socket joint
Round head in cup
Widest range of motion
Hip, shoulder
Ball and socket joint
Round head in cup
Widest range of motion
Hip, shoulder
Candylar joint
Oval into elliptical cavity
Back and forth, side to side
Between metacarpals and phalanges
Plane joint
Flat, slightly curved
Back and forth and twisting
Wrist(carpal) anxie tarsal
Hinge joint
Convex surface into concave
Elbow, joints between phalanges
Pivot joint
Rotation only
Cylindrical surface
Atlas(c1) and axis(c2)
Saddle joint
Both concave and convex
Carpal and metacarpal of thumbs
Shoulder joint
Ball and socket Several bursae(sacks of synovial fluid) Very wide range, rotation, and circumduction
Shoulder joint major ligaments
Coracohumeral
Glenohumeral
Transverse humeral
Elbow joint
Hinge joint- fexion and extension
Plane joint-pronation and supination
Elbow joint major ligaments
Radial collateral
Ulnar collateral
Anular collateral
Hip joint
Ball and socket
Head of femur
Acetabulum of hip bone
Variety of movement, less than shoulder
Hip joint major ligaments
Iliofemoral-(strongest)
Pubofemoral
Ischiofemoral
Knee joint and the 3 bones
Largest and most complex -femur -tibia -patella Bursae and fat pads
Knee joint major ligaments
Patellar Medial Lateral Anterior Posterior
Replacing joints
Synthetic material is used to replace joints
-steel and titanium
Most common in hip
Joint disorders
Sprains
Bursitis
Anthritis
Sprain
Tearing
Bursitis
Inflammation of bursae
Arthritis
Rheumetoid arthirtis- autoimmune
Osteoarthritis-degenerative, most common
