Skeletal

• 206 bones
• joint is where 2 bones meet
• cartiliage is at the end of a bone

Types of Connective Tissue

Cartiliage:

1. hyaline 

2. Fibron

3. Elastic

E.g. joints, spinal discs and ears

• Ligaments - connect bone to bone for stability
• Tendons - attach muscle to bone to transfer forces to the skeleton

FUNCTION

• - Framework
• - protect organs
• - surface for muscle attachment
• - produce red & white blood cells
• - store minerals e.g. calcium
• - provide levers for muscle movement

• axial - skull, rib cage & spine
• Appendicular - limbs & anchoring bones

SPINE Vertabrae

• 7 Cervical
• 12 Thoracic
• 5 Lumbar
• 5 Sacral (Sacrum)
• 4 Sacral (Cocyx)

Bones - Classified according to their shape

• Long, short, flat, irregular & Sesamoid

Bone Formation  I.E. Ossification

• Living tissue with its own blood supply
• Osteoblasts - Build new tissue bone
• Osteoclasts - Clear away old or damaged bone tissue

Types of Bone Growth

• Endochondral - bone formed from a cartilaginous model
• Intramembranous - bone formed from a membranous structure

Bone Formation

1, Cartilaginous / Membraneous Model

2. Woven Bone

3. Lamellar Bone

Bone Repair

Inflammation - pain. swelling, redness & reduced ROM

Soft Callus - Granulation tissue becomes collagen & cartilage formed

Hard Callus - Woven bone laid into collagen matrix

Remodelling - Lamellar bone replaces woven bone
