Assisting in movement
Function of bone
Triglyceride storage
Function of bone
The membranous outer covering of long bone
Periosteum
The method of ossification forming most bones
Endochondral
The enlarged ends of a long bone
Epiphyses
Articulate cartilage is an example of the cartilage type
Hyaline
The center of an osteon which carries blood vessels longitudinally through bone
Haversian canal
The shaft of a long bone
Diaphysis
Rings of bony tissue filled with minerals and surrounding the Haversian canal
Lamellae
Mature bone cells
Osteocytes
Bone that contains numerous air spaces between cells
Spongy
Microscopic cavities in bone containing osteocytes
Lacunae
A 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
Canaliculli
The unit of structure in compact bone
Haversian system
The mineral part of bone
Matrix
The “growth area” in bones where epiphysis joins diaphysis
Epiphyseal plate
Bone is an example of this major tissue type
Connective
Bone disorder characterized by decreased bone mass and increased susceptibility to fractures
Osteoporosis
The area of a long bone containing the thickest layer of compact bone
Diaphysis
Secrete cartilage matrix
Chondroblasts
Involved in bone resorption
Osteoclasts
Mature cartilage cells
Chondrocytes
Mature bone cells
Osteocytes
Cells that form cells
Osteoblasts
When trying to locate a foramen in a bone, you would look for
An opening or hole
The ribs articulate with a
Thoracic vertebrae
Run lengthwise through bone
Haversian canal
Connect central canals with lacunae
Canaliculi
Concentric rings of matrix
Lamellae
Connect nutrient arteries and nerves from the periosteum to the central canals
Volkmanns canal
The presence of an Epiphyseal line in a long none indicates that the bone
Has stopped growing in length
The hyoid bone is unique because it
Does not articulate with any other bone
The bones that form the pectoral girdle are the
Clavicle and scapula
The main hormone that regulates the ca2+ balance between bone and blood is
Parathyroid hormone
Spongy bone differs from compact bone because spongy bone
Las latticework walls known as trabeculae
