Skeletal 2
Synovial Joint
Articular cartilage on bone ends, frictionless movement and shock absorption
-
-
Synovial fluid: lubrication, nutrients, and waste removal

Bone repair
Formation of blood clot, local cells die, macrophages transported through blood arrive and clean area
Formation of fibrocartilaginous callus, fibroblasts and chondroblasts deposit collagen fibers around to form a fibrocartilage mold around fracture sight, known as soft callus
Formation of bony callus, osteoblasts create spongy bone connecting bone ends
Remodeling, osteoclasts/osteocytes smoothen bony callus
Hyaline cartilage (rib), elastic cartilage, fibrocartilage
Joint
-
-
Fibrous joint: Forms when edge of bones are firmly held together by dense fibrous connective tissue (immobile, e.g. skull)
Cartilaginous joint: formed when edges of bone are held together by ridged cartilage bridge (immobile and partly mobile)
Synovial joint: form when edges of bone do not make contact but are held together by a joint capsule (freely mobile)
Trabeculae
Individual strut like bony units, spongy bone is a latticework of trabeculae, you will only find trabeculae in spongy bone
Contains lamella arranged in plates or sheets, lacunae and canaliculi for osteocytes
