Chapter 7 Review Flashcards
epiphysis
- Located at the end of a long bone and articulates with another bone to form a joint
articular cartilage
- A layer of hyaline cartilage that coats the articulating portion of the epiphysis.
diaphysis
- The shaft of the bone
metaphysis
-the widening part of the bone between the diaphysis and epiphysis
periosteum
- A tough, vascular covering of dense connective tissue, except for the articular cartilage on its ends.
- Form and repair bone tissue
compact bone
-tightly packed tissue
spongy bone
-thick layers of compact bone on their surfaces
short bone
-Short bones: cube like, with roughly equal lengths and widths. Tarsals and Carpals
flat bone
-Flat bones: platelike structures with road surfaces, such as ribs, scapula, and some bones in the skull
irregular bone
-Irregular bones: variety of shapes, most are connected to several other bones. Vertebrae that compose the back bone and many facial bones.
medullary cavity
- A hollow chamber formed by a tube in the diaphysis of a long bone.
endosteum
- a thin membrane containing bone-forming cells
- it lines the medullar cavities
marrow
-a specialized type of connective tissue
osteocytes
-bone cells
osteon(Haversian canal)
-central canal of bone cells
lamellae
-layers of extracellular matrix in compact bone
lacunae
-bony chambers, which house osteocytes
canaliculi
-way for cells to travel throughout the bone
perforating canals(Volkmann’s canals)
connects the central canals
intramembranous bones
- flat bones
- skull, clavicle, sternum, mandible, maxillae, and zygomatic
endochondral bones
-develops from hyaline cartilage
osteoblasts
-bone forming cells
