Chapter 7- Articulations Flashcards by Dicey Lucas

Q

Name and describe three classes of joints based on structure

A

Fibrous Joints: NO synovial cavity, and the bones are held together by fibrous CT (Rich in Collagen fiber).
Cartilaginous Joints: NO Synovial cavity, and the bones are held together by cartilage.
Synovial Joints: Bone forming joints HAVE synovial cavity, and are united by dense irregular CT
