Joints 1 Flashcards
Primary ossification centre
Diaphysis
Secondary ossification centre
Epiphysis
Bone growth in length is enabled by
Epiphyseal plates (growth plates)
Bone growth in width
Appositional growth
Types of cartilage
Hyaline, fibrocartilage
Cartilage cells
Chondrocytes
Hyaline cartilage function
Resist compression
Fibrocartilage function
Resist compression and tension
DFCT
Dense fibrous connective tissue
Cells that make DFCT
Fibroblasts
DFCT function
Resist tension
Ligaments
Connect bone to bone
Ligaments in movement
Restrict movement away from themselves
Tendons
Connect muscle to bone
Bony congruence
Sum of bone surfaces that form an articulation
Low bony congruence
Low surface area, more soft tissue support needed
High bony congruence
High surface area, less soft tissue support needed
Fibrous joints
Least amount of movement
Cartilaginous joints
Some movement
Synovial joints
Most amount of movement
