Chapter 6 Flashcards
Membranous outer covering of a long bone
Periosteum
6 functions of bones
Protection, support, movement, mineral homeostasis, production of blood cells, triglyceride storage
Method of ossification forming most bones
Endochondral
Enlarged ends of a long bone
Epiphyses
Articular cartilage is an example of what cartilage type
Hyaline
Center of an osteon which carries blood vessels longitudinally through bone
Haversian canal
Shaft of long bone
Diaphysis
Rings of bony tissue filled with minerals and surrounding Haversian canal
Lamellae
Mature bone cells
Osteocytes
Bone that contains numerous air spaces between cells
Spongy
Microscopic cavities in bone containing osteocytes
Lacunae
Space in bone which contains marrow
Medullary canal
Bone forming cells
Osteoblasts
Very dense bone with no air spaces within
Compact
Small channels connecting lacunae with each other
Canaliculi
Unit of structure in compact bone
Haversian system (osteon)
Mineral part of bone
Matrix
Growth area in bones where epiphysis joins diaphysis
Epiphyseal plate
Bone is what tissue type
Connective
Bone disorder characterized by decreased bone mass and increased susceptibility to fractures
Osteoporosis
Area of long bone containing the thickest layer of compact bone
Diaphysis
three bones that fuse together to form the hip bones
Ilium, ischium, pubis
Type of bone that forms most of the Epiphyses of long bones and consists of trabeculae that surround spaces filled with RED bone marrow
Spongy
Formation of bone
Ossification
Only movable bone in the skull
Mandible
Ribs and cranial bones are classified as what type of bone
Flat
When aging bones become more or less brittle?
