Chapter 8 Flashcards
Synarthroses
Immovable
Articulation
Site where two or more bones meet
Amphiarthroses
Slightly moveable
Diarthroses
Freely movable
Fibrous joints
- fibrous connective tissue
- no joint cavity
- ## synarthrotic ( immovable )
FB
- suture
Puzzle pieces in skull
- grout as youth
- interlocked joints
Synostroses
Fb
- syndesmoses
- ligaments
- amp & di
- bottom of fibula & tibia
Fb
- gomphoses
Holds joints in lock
Connection
Cartilaginous joints
Bones united by cartilage
- no joint cavity
Cartilaginous joints
- synchondroses
A bar or plate of hyaline cartilage with bone
- all synarthrotic
Cartilaginous joints
- syphyses
Hyaline cartilage covers articulating surfaces
- fused with fibrocartilage
Synovial joints
Diarthrotic
- most joints in body
⬇️
⬆️
Tendon sheath
Elongates brusa that wraps around a tendon
Non axial
Slipping movement only
Uniaxial
Movement one plane
Biaxial
Movement in 2 planes
Multiaxial
around all 3
Plane joint
Non axial
- flat
- short glide
Hinge joint
Uni axial
- motion along single plane
- flex atom and extension. Only
Pivot joints
Round end of one bone = sleeve
Single movement
Condyloid joint
Bi
- both articulatar are oval
- permit all angular movements
Saddle joint
Bi
- more freedom than condyloid
- both concave and convex areas
Ball n socket joint
Multiaxial
- free of them all synovial
Knee joint
Most complex
-3 surrounded by 1 joint
12 bursae
-
Shoulder (glenohumeral) joint
Ball n socket
- stability sacrifices
Coracohumoral- support weight
- 3 glen… Weak
Sprain
Stretched or torn
- slow repair
- may need surgery
Cartilage tears
Rarely repair
- joint lock or bind
- shear stress
- a surgery
Dislocation (luxurions)
Forced out of alignment
- sprain, inflammation, joint immobilization
Subluxation
Half dislocated
Brusitis
Inflammation brusa
- use ice or drug
tendinitis
Inflammatory of tendons (over use)
- ice, rest drug
Osteoarthritis
85%
Aging
- no help
