Module 4 Flashcards
Bone, cartilage, tendons, and ligaments of the skeletal system are all what?
Connective tissues
Tough, ropelike protein
Collagen
Large molecules consisting of many polysaccharides attaching to and encircling core proteins
Proteoglycans
Extracellular matrix containing collagen and proteoglycans
Cartilage Extracellular Matrix
Relatively rigid, but springs back to its original shape after being bent or slightly compressed and is an excellent shock absorber
Cartilage
Extracellular matrix containing collagen and minerals, including calcium and phosphate
Bone Extracellular Matrix
Shape classification of bone that are longer than they are wide
Long bones
Shape classification of bone that are approximately as wide as they are long
Short bones
Shape classification of bone that have relatively thin, flattened shape
Flat bone
Shape classification of bone that include the vertebrae and facial bones
Irregular bones
Long bone structure that is a shaft and compact bone tissue on the outside
Diaphysis
Long bone structure that have spongy bone ends and articular cartilage that covers it
Epiphysis
Long bone structure that is the site of growth between diaphysis and epiphysis
Epiphyseal plate
Long bone structure that is the center of diaphysis red or yellow marrow
Medullary cavity
Long bone structure that is the membrane around bone’s outer surface
Periosteum
Long bone structure that is the membrane that lines medullary cavity
Endosteum
Soft tissue that fill spaces or cavities
Marrow
Marrow that Is the location of blood forming cells
Red marrow
Marrow that is mostly fat
Yellow marrow
Located in the outer part of diaphysis and thinner surfaces of other bones
Compact Bone Tissue
Structural unit of compact bone
Osteon
Rings of bone matrix
Lamella
Spaces in between lemalla
Lacunae
Tiny canals that transport nutrients and remove waste
Canaliculus
Center of osteon and contains blood vessels
Central Canal
Located at the epiphyses of long bones and center of other bones. Has trabeculae, which are interconnecting rods and has no osteons
Spongy bone
Responsible for the formation of bone and the repair and remodeling of bone
Osteoblasts
Cells that maintain bone matrix and form from osteoblast after bone matrix has surrounded it
Osteocytes
Contribute to bone repair and remodeling by removing existing bone, called bone reabsorption
Osteoclasts
Is the formation of bone by osteablasts
Ossification
Bone formation that occurs within connective tissue membrane is called what?
Intramembranous ossification
Bone formation that occurs inside hyaline cartilage is called what?
Endochondral Ossification
Where does intramembranous ossification process begin at?
Ossification Centers
Bone formation within a cartilage model
Endochondral Bone formation
Bone formation in the diaphysis of a long bone
Primary ossification Center
Bone formation in the epiphysis
Secondary Ossification Center
Bone growth occurs by the deposition of new bone lamellae onto
existing bone or other connective tissue. As osteoblasts deposit new bone matrix on the surface of bones between
the periosteum and the existing bone matrix, the bone increases in
width, or diameter. What is this process?
Appositional growth
Bone fracture wherein bone fragments into three or more pieces
Comminutes Fracture
Bone fracture wherein ragged break occurs when excessive twisting forces are applied to a bone
Spiral Fractures
Bone fracture wherein broken bone portion is pressed inward
Depressed Fracture
Bone fracture wherein bone is crushed
Compression Fracture
