1.
Adult skelteton has how many bones?: 206
2.
Appendicular Skeleton: the bones of the limbs and the girdles
3.
Articular Cartilage: Covers the ends of the epiphyses; Provides a smooth, slippery surface that decreases friction at joint surfaces
4.
Axial Skeleton: the bones that form the longitudinal axis of the body
5.
bone markings: bumps, holes, and ridges that reveal where muscles, tendons, and ligaments were attached and where blood vessels and nerves passed
6.
Diaphysis: Shaft of the long bone; composed of mostly compact bone
7.
Epiphyses: End of th long bone
8.
Flat bones: thin, flattened, and usually curved;
most bones of the skull, ribs, and sternum
9.
Four groups of bones:: Long
Flat
Short
Irregular
10.
Functions of the bones include: Support(internal framework that supports the body
Protection (Soft body organs)
Movement (Acts as levers to move the body and its parts)
Storage (fat, minerals)
Blood Cell Formation (hematopoiesis)
11.
How to memorize bone depressions: All terms beginning with the "F" (except facet)
12.
How to memorize bone projections:: All terms beginning with the "T"
13.
hypercalcemia: when blood cacium levels are too high
14.
Irregular bones: bones that do not fit oneof the preceding categories;
vertebrae and hip bones
15.
Long bones: Typically longer than they are wide;Mostly compact
All bones of the limbs and the wrist and ankle bones (except kneecap or patella)
16.
Ossification: process of bone formation
17.
osteclasts: giant bone-destroying cells in bones
18.
Osteoblasts: bone-forming cells
19.
Osteocytes: Mature bone cells
20.
Perisosteum: Fibrous connective tissue membrane that covers and protects the diaphysis of the long bone
21.
Red marrow: found in the cavity of the shaft of young bones;
confined to the cavities in the spongy bone of flat bones and the epiphyses of some long bones in adult bones
22.
Short bones: cube-shaped and contain mostly spongy bone ;
bones o f the wrists and ankles
23.
Skeletal system: consists of bones, ligaments, joints and cartilages
24.
Two categories of bone markings are:: A. Projections (processes)- grow out from the bone surface
B. Depressions (cavities)- indentations in the bone
25.
Two divisions of the skeleton: Axial and Appendicular
26.
Two major typesof bone or osseous tissue:: Compact bone-dense and looks smooth and homogenous
Spongy bone- composed of small needle-like pieces and lots of open space
27.
Yellow marrow (medullary cavity): cavity of the shaft;
storage area for adipose tissue in adults:
