Joints Flashcards
The Three Types of Joints?
Synovial
Fibrous
Cartilaginous
Fibrous Joints are classed as?
Synarthrosis joints: little/no movement
Types of fibrous joints
Gomphosis joints
Syndesmoses (fastened with a band)
Sutures
Cartilaginous Joints are classed as?
(amphiarthroses)
- allow limited or no movement
Cartilaginous Joints types?
SYNCHONDROSES- hyaline cartilage
SYMPHASES -fibrocartilage
Example of a cartilaginous joint
Pubic
vertebrae
Mandibular
Synovial Joints
DIARTHROSES
- allow a wide range of movement
structural components of Synovial Joints
Synovial fluid
Synovial membrane
Joint capsule
Meniscus/menisci
Intra-articular discs of
fibrocartilage act as shock
absorbers within joint
Example of a Hinge Joint
- Elbow *
flexion and extension
Example of a Condylar Joint
- carpal joint *
Example of a Pivot Joint
atlantoaxial joint
Example of a Ball and socket
HIP
Example of a Plane Joint
Small bones of carpus & tarsus
Examples of Saddle Joint
Shoulder
whats an Articular fracture?
Fracture involving the joint
whats a Depressed fracture?
indent (to the skull
What is a compression fracture?
compressive force has
resulted in the shortening of a vertebra by a crushing effect.
what is a Fissure fracture?
a fine crack- vulnrable to displace
What is an Avulsion fracture?
bony prominence has been torn away from the rest of the bone
what is the Salter-Harris System
growth plate fractures are classified by the SALTER
Luxation (Dislocation)
displacement
Subluxation
Partial displacement
