Exam 3- Chapter 8 Flashcards
Site where two are more bones meet
Articulation
Functions of joints
- Give skeleton mobility
2. Hold skeleton together
Weakest parts of the skeleton
joints
immovable joint
synarthroses
slightly moveable joint
amphiarthroses
freely moveable joint, most common type
Diarthroses
Fribrous joints
- Sutures
- Syndesmoses
- gosmophoses
RIgis interlocking joints containing shorts connective tissue fibers, allow for growth
sutures
Bones connected by ligaments
Syndesmoses
peg-in-socket joints of teeth in alveolar sockets
gomphoses
bones united by cartilage, no joint cavity
cartilaginous joints
two types of cartilaginous joints
- Synchondroses
2. Symphyses
A bar or plate of hyaline cartilage unites bone
Synchondroses
Hyaline cartilage covers the articulating surfaces and is fused to an intervening pad of fibrocartilage, acts as a shock absorber to prevent to much movement
Symphyses
All are diarthrotic, include all limb joints
Synovial joints
Lubricates and nourishes articular cartilage
Synovial fluid
reinforcing ligaments
- Capsular
- Extracepsular
- Intracapsular
part of the fibrouscapsule
capsular
outside of the capsule
extracapsular
deep to capsule; covered by synovial membrane
intracapsular
detect pain and monitor joint position and stretch
rich nerve fibers
