Skeletal System chapter 5

Cartilage consists primarily of water which accounts for its resilience. T or F

3 types of cartilages tissue in the body

Look like frosted glass when freshly exposed. Provide support with flexibility and resilience, chondrocytes are spherical

cover the ends of most bones and movable joints

connect the ribs to the sternum

form the skeleton of the larynx and reinforce other respiratory passageways

supports the external of nose

Elastic Cartilages structure types and location

highly compressible with great tensible strength. consist of roughly parallel rows of chondrocytes alternating with thich collagen fibers

cartilages grows jn 2 ways

cartilage forming cells in the surrounding perichondrium

the lacunae bound condrocytes divide the secrete new matrix

forms the long axis of the body and includes the bones of the skull

consists of the bones of the upper and lower limbs and the girdles

compact bone

internal layer made up of honeycomb of small needle like flat pieaces called trabeculae

covers internal bone surfaces

(hematopoietic) within the trabecular cavities of spongy bone of long bones and flat bones

fats in the medullary cavity

unit of bone

Opening in the center of an osteon. Carries blood vessels and nerves.

Canal perpendicular to the central canal. Carries blood vessels and nerves

bone develops by replacing hyaline cartilage. resulting the bone is called cartilage or endochondral bone.

bone develops from a fibrous membrane and the bone is called a membrane bone

_____ law holds that a bone grows or remodels in responses to the demands placed on it.

determine whether and when remodeling occurs in response to changing blood calcium

determines where remodeling iccurs

analogous disease in children

(Soft bones) includes a number of disorders in which the bones are poorly mineralized

it is a disease by excessive and haphazard bone deposit and resorption
