Chapter 5 Flashcards
Appendicular skeleton
Bones of the limbs and limb girdles that are attached to the axial skeleton.
Amphiarthroses
A slightly movable joint
Articular cartilage
The cartilage covering the articular surfaces of the bones forming a synovial joint.
Articulations
Joint; point where two bones meet.
Axial skeleton
The bones of the skull, vertebral column, thorax, and sternum
Bony thorax
Bones of the thorax, including ribs, sternum, and thoracic vertebrae.
Cartilaginous joint
Joints connected entirely by cartilage. Allows more movement between bones than a fibrous joint but less than the highly mobile synovial joint.
Compact bone
Dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces that contain the bone cells
Diaphysis
The main or midsection (shaft) of a long bone.
Pelvic girdle
Incomplete bony basin formed by the two coxal bones that secures the lower limbs to the sacrum of the axial skeleton.
Periosteum
Double-layered connective tissue that covers and nourishes the bone
Red marrow
Flexible tissue in the interior of bones. Found mostly in the flat bones.
Short bones
Bones that are as wide as they are long.
Shoulder girdle
Composite of two bones, scapula and clavicle, that attach the upper limb to the axial skeleton; also called the pectoral girdle.
Skull
Bony enclosure for the brain.
