What is extracellular Martix? |
Jelly like substance and fibers |
|
|
Hyaline Cartilage? |
Provides support with flexibility and resilience |
|
|
Elastic cartilage? |
Resembles hyaline, contains stretchy elastic fibers and is able to conduct repeated bending |
|
|
Fibrocartilage? |
Great tensile strength |
|
|
Perichondrium? |
Connective tissue, covering the hyaline cartilage and converts to periostum (double layered membrane that covers external surface of bone except joints) |
|
|
Appositional Growth? |
Cartilage forming cells in the surrounding perichondrium (Connective tissue) secrete new matrix against the external face of the existing cartilage tissue. |
|
|
Interstitial growth? |
The lacunae bound chondrocytes divide and secrete new matrix, expanding the cartilage within |
|
|
Functions of the skeleton? |
Support, protection, anchorage of muscles, mineral growth, bloodcell formation, fat storage, hormone production |

Spongy bone is the internal layer of bone. Compact bone the external layer of bone. |
|
|
Trabeculae? |
A honey comb or small needle like or flat pieces of bone. |
|
|
Diaphysis? |
Shaft that forms the long axis of bone |
|
|
Epiphyses? |
Bone ends |
|
|
Epiphyseal line? |
Located between the diaphysis and epiphyses of an adult ling bone, a remnant of the epiphyseal plate (growth plate in children) |
|
|
Periosteum |
Double layered membrane that covers external surface of bone except joints. |
|
|
Endosteum |
Covers internal bone, connective tissue membrane. |
|
|
Hemotopoietic tissue? |
Red bone marrow |
|
|
Types of bone markings? |
Projections- Bone markings the bulge outward from the surface. Depressions and openings- Allow nerves and blood vessel to pass. |
