Ch 3 Articular System Flashcards
3 types of fibrous joints
Synarthrosis, syndesmosis, gomphosis
3 types of joints
Fibrous
Cartilaginous
Synovial
Fibrous joint
Thin layer of fibrous periosteum between two bones
Ex:sutures in skull
Synarthrosis
Suture joint
Syndesmosis
Ligamentous joint. Great deal of fibrous tissue holding the joints together
Ex: interosseous membrane
Cartilaginous joint
Amphiarthrodial joint
Either hyaline cartilage or fibrous cartilage between the two bones.
Ex: vertebral joints
Synovial joint
Diarthrodial joint
No direct union between the bones. Instead, there is a capsule filled with synovial fluid.
Classifications of diarthrodial joints
Non axial, uni axial, biaxial, triaxial
Non axial joint
Irregular plane
Gliding
Ex: intercarpals
Uniaxial
Angular motion in one plane around one access
Hinge joint
Ex: elbow
Biaxial joint
Occurs in two different directions
Ex: the wrist
Triaxial joint
Has motion in all 3 axis
Ball and socket
Ex: shoulder
Ligaments
Bone to bone
Tendons
Muscle to bone
Synovial membrane
Thick vascular connective tissue that secretes synovial fluid
