Bones Flashcards
Absence of calcium, no exposure to sunlight, a condition in child and adult
Rickets -a condition in child
Osteomalacia-a condition in adult
Ball and socket joint
Coming from scapula
Glenoid Cavity
Synovial cavity inflamed water on the knee caused by a blow
Bursitis
Mature bone cells
Osteocytes
Does not fit the bone classification
Irregular bone
Metacarpal phalanges
Moved side to side
Move front to back
Condyloid joint
Where muscle, tendons, and ligaments were attached and where blood vessels and nerves passed
Bone markings
Forms within tendons, a special type
Of short bones, ex patella
Sesamoid bones
Major anatomical area of long bones
Diaphysis
Epiphysis
Metaphysis
Periosteum
Endosteum
Classification according to shapes
Long bones
Short bones
Flat bones
Irregular bones
Provides stiffness/ hardness of bones
Maintains structural integrity of bone
Bone salts
Provides flexibility and tensile strength
Absorb energy- excessive flexibility
Organic matrix
Riddled passageways carrying nerves, blood vessels, provide living bones cells with nutrients and route for waste disposal
Compact bone tissues
Mature cell bones
Osteocytes
Osteocytes are found within the matrix in tiny cavities
Lacunae
Lacunae are arranged in concentric circles called
Lamellae
Lacunae are arranged in concentric circles called lamellae around the?
Central (haversian) canals
Central canals run lengthwise through the bony matrix, carrying blood vessels and nerves to all areas of the bones. Tiny canals that radiate outward from the central canals to all lacunae?
Canaliculi
The communication pathway from the outside of the bone to its interior is completed by
Perforating canals
Volkmann’s canals
Hardest material in the body
Bone
Large, rounded projection; may be roughened
Tuberosity
Anatomical name for the shaft of a long bone, long tubular section that provides structural support
Diaphysis
Skeleton is formed from two of the strongest and most supportive tissues in the body
Cartilage and bone
Process of bones formation by osteoblasts
Ossification
Process of bones formation by osteoblasts
Ossification
Bones increase in diameter
Appositional growth
Flat footed
Fallen arches
Sesamoid
in a tendon
Patella
Disease of children in which bones fail to calcify
Rickets
Bones begin as?
Hyaline cartilage
Which stimulus -PTH or mechanical forces acting on the skeleton- is more important in maintaining blood calcium levels than in maintaining bone strength
Parathyroid hormone
Plays a more critical role in calcium homeostasis
Parathyroid hormone
If osteoclasts are more active than osteoblasts
Decrease in bone mass
