Joints Flashcards
4 MAJOR TYPES
BONY
FIBROUS
CARTILAGINOUS
SYNOVIAL
SYNOSTOSIS
Type of joint
No movement occurs between the bones
Bony joint
SYNARTHROSIS
Type of joint
Joint allowing little movement
Fibrous joints
AMPHIARTHROSIS
Type of joint
Provides moderate movement
Cartilagenous joints
DIARTHROSIS
Free movement
Synovial joints
3 types of Fibrous Joints
Suture
Gomphosis
Syndesmosis
Suture joint
Fibrous joint between cranial bones
Gomphosis
TOOTH
Between tooth and mandible/maxilla
Gomphosis
TOOTH
d
Syndesmosis
Fibers a little longer, allowing movement in side-by -side bones
Radius.ulna tib.fib
2 types of cartilagenous joints
Synchondrosis
Symphesis
Synchondrosis
Cartilagenous joint bount by hyaline cartilage
Ex in kids between diaph/epyph, rib/sternum
Symphysis
Bones bound by thich layer of fibrocartilage
Ex pubic symphysis, intervertebral discs
Tendon
Attaches muscle to bone
Ligaments
Attach bone to bone
Bursa
Fluid-filled sac that cushion and alleviate tendon/bone rubbing
Articular disc
Fibrocartilage extending across joint cavity to create sectioned areas of synovial fluid
Ex temporal mandibular joint ends of clavicles, ulna/carpal
Meniscus
Fibrocartilage pad in knee joint that absorbs extra force
Name the three planes of movement of synovial joints
Monaxial
Biaxial
Multiaxial
6 forms of synovial joints
Ball and socket
Condylar
Saddle
Plane
Hinge
Pivot
Describe the structure of a synovial joint
Joint capsule (where synovial fluid is produced) surrounds the whole joint cavity
2 parts of a synovial joint capsule
Outer fibrous capsule - holds joint together and retains fluid
Inner synovial membrane - produces synovial fluid
