Types of Joints Flashcards
Name types of joints
fibrous
cartilaginous
synovial
Fibrous
& example
immovable and interlocking bones joined by fibrous tissue that is rich in collagen fibres
- cranium
Cartilaginous
& example
slightly moveable and the bones are joined together by cartilage
- manubriosternal joint
Synovial
freely moveable and are the most common type of joint in the body
- pateellofemoral (knee) joint
Name the types of synovial joints
- gliding/plane joints
- hinge joints
- pivot joints
- saddle joints
- ball and socket joints
- condyloid/ellipsoid joints
What are the characteristics of synovial joints?
- ends of bone covered with hyaline
cartilage - surrounded by a fibrous capsule
- capsule lined by a synovialmembrane that secretes synovial
fluid for lubrication - enclosed by ligaments for stability
Gliding/plane joint example
acromioclavicular joint
Hinge joint example
knee
Pivot joint example
atlanto-axial joint
Condyloid/ellipsoid joint example
metacarpophalangeal joint (knuckles)
Saddle joint examples
carpometacarpal joint (thumb)
Ball and socket joint examples
hip
Gliding/plane joint function
allow 2 bones to slide past each other
Hinge joint function
bones can only move through flexion and extension
Pivot joint function
allows rotation around an axis
Ball and socket joint function
allows movement in almost any direction- the greatest amount of joint movement in body
Condyloid/ellipsoid joint function
similar to ball and socket, but allow lesser degree of movement
Saddle joint function
similar to ball and socket/saddle, but without rotational movement
