Bone And Cartilage Flashcards
Osteocytes
Bone cells trapped in the bone matrix
Osteoblasts
(Bone lining cells) bone building
Osteoclasts
Bone resorption cells ( bone remodeling )
Organic matter
( osteoid) Type I collagen + ground substances
Inorganic matter
Calcium phosphate
Fibroblasts
Secreting fibers and ground substances
Macrophages
Removing dead cells and damaged fibers
Periosteum
Two layers , inner osteoblasts and outer dense irregular CT
Endosteum
Loose CT lining canals and all internal spaces within the bone
Name
Canaliculus
Chondroblasts
Mitotic synthesizes matrix
Chondrocytes
Secretes matrix, round cells , prominent nucleolus, basophilic cytoplasm
Chondroclasts
Multinucleated. Resorb cartilage for remodeling (degeneration zone )

Variation in shape
Rouleaux formation
When do you see monocytes
Inflammation, damage, phagocytic
When do you see lymphocytes
Viral infection , cancer
When do you see neutrophils
Bacterial infection
When do you see basophils
Allergens
When do you see eosinophils
Parasites
Lymphocytes
Monocyte
Osteoclasts/ chondroclasts
Eosinophils
Rouleaux formation
Due to increase in blood plasma protein
Monocytes can become
Macrophages
Some dendritic cells
Microglia
Osteoclasts
Band cell neutrophils
Immature
