What type of tissue is bone?
Connective tissue
What is the mature bone cell called?
Osteocyte
Where are osteocytes located?
The matrix of the bone, composed of collagen fibers and a great amount of crystallized tricalcium phosphate (hydroxyapatite)
What are the two types of bone?
Spongy and compact
What is another name for an osteon?
Haversian systems
What is a lacuna?
The cavity where osteocytes are found
What is a canaliculi?
Small canals that radiate from the lacuna that contain the processes of the osteocytes
What is a lamellae?
The bony matrix is laid down in concentric rings
What is found in between lamellae?
Osteocytes, lacunae, and canaliculi
Where is the central canal, and what is another name for it?
Located in the center of the osteon, running vertically, Haversian canal
Where are perforating canals, and what is another name for them?
Running horizontally through compact bone, Volkmann’s canals
