L2 Flashcards
What do bones begin as?
cartilage model
What is endochondral ossification?
Transforming cartilage into bone
What is the primary centres of ossification?
diaphyses
What is the secondary centre of ossification
epiphyses
What is the epiphyseal plat and its function
plate of cartilage between diaphyses and epiphyses which facilitate long growth
What is a joint and its function?
Where bones articulate and holds them together for movement
What are the two types of cartilage
Hyaline
fibrocartilage
How does cartilage get its nutrients?
Through joint loading (diffusion of nutrients)
What is make up and function of hyaline cartilage
collagen fibres barely visible
high water content
resists compression allowing smooth and frictionless surface
makeup and function of fibrocartilage
Collagen fibres form bundles throughout matrix
Orientation of fibres aligns with stresses to resist compression and tension
ligaments make up and function
Elastin and collagen which allows recoil
Connects bone to bone
restricts movement
Tendons make up and function
Connect muscle to bone
Facilitates movements from contraction of muscles
What is the order from least to most movement of the 3 types of joints
Fibrous, cartilaginous, synovial
What is fibrous joints made of and function
DFCT ligaments
provide stability
What is cartilaginous joints made of and function
Fibrocartilage
allows for some movement
