| Question | Answer |
| What does collagen usually stain | acidiphilic |
| What is the territorial matrix | area adjeacent to chondrocytes. Lacks fibers and can affect staining |
| What is the perichondrium | vascular layer around the cartilage that provides support |
| 2 layers of perichondrium | fibrous layer and chondrogenic layer |
| What makes up the fibrous layer | type 1 collagen and fibroblast |
| Is the fibrous layer vascular | YES |
| What makes up the chondrogenic layer | undifferentiated cells that give rise to chondrocytes |
| Describe appositional growth | cells of chondrogenic layer proliferate and turn to chondroblast. They then lay down cartilage layer by layer |
| describe interstital growth | chondrocytes within the cell expand divide. Their daughter cells then lay down cartilage. About 70% water |
| Unique feature of elastic cartilage | scratchy appearence, fewer nest cells, and type 2 collagen |
| Unique features of Fibrocartilage | No perichondrium, type 1 collagen fibers, chondrocytes line up on the edge of fibers, HERRINGBONE, deeply acidiphilic |
| Where is fibrocartilage usually found | tendon insertions, pubic symphysis, annulus fibrosus. Anywhere tensile strength and support is needed |
| What part of the bone does the diaphysis develop into | the longer parts |
| Epiphysis makes up which part of the bone | the ends or heads of the bones |
