Q1 Anatomy
Bones and Skeletal Tissues
Question | Answer |
---|---|
A resilient tissue that springs back to its original shape | Cartilage |
Most abundant of the cartilages, Provides support through flexibility | Hyaline Cartilage |
Type of cartilage that contains many elastic fibers | Elastic Cartilage |
An intermediate cartilage between hyaline and elastic, Resists tension and compression | Fibrocartilage |
Functions of bones (5) | Support, Movement, Protection, Mineral Storage, Blood-Cell Formation |
Bones that are longer than they are wide (shaft-like) | Long Bones |
Bones that are roughly cube shaped | Short Bones |
Bones that are thin, flat and usually curved | Flat Bones |
Bones that do not fit into the other categories of bones | Irregular Bones |
The dense outer layer of bone | Compact Bone |
The internal network of bone | Spongy Bone |
"Shaft" of a bone | Diaphysis |
Ends of a bone | Epiphysis |
The hollow cavity in the shaft of the bone filled with yellow marrow, Stores fats | Medullary Cavity |
The fibrous membrane that covers the external surfaces of bones | Periosteum |
Fibers extending from the periosteum into the lamellae of the bone | Sharpey's Fibers |
The membrane lining the medullary cavity of bone and other inner bone surfaces | Endosteum |
The microscopic bone unit of compact bone consisting of Haversian canals and the surrounding lamellae, | Osteon/Haversian System |
A group of concentric tubes that bear weight | Osteons |
A layer of bone matrix consisting of collagen fibers and mineral crystals, Withstands twisting, stress and torsion | Lamella/Lamellae |
Microscopic structure running through each osteon, Consists of blood vessels and nerve fibers | Central/Haversian Canal |
Microscopic structure that connects the blood and nerve supply of the periosteum to the central canals and marrow cavity | Volkmann's Canal |
Mature bone cells | Osteocytes |
Small cavities occupied by osteocyte bodies | Lacunae |
Small cavities occupied by osteocyte "legs" | Canaliculi |
