Answer 3

most common form of GAG

Question 4

osteon/haversion system

Answer 4

functional unit of bone at the microscopic level

Question 5

haversion canal

Answer 5

lies at the center of each osteon, contains blood vessels and nerve fibers

Question 6

Osteons consist of concentric series of mineralized matrix layers called:

Answer 6

lamellae

Question 7

osteocyte

Answer 7

bone cell

Question 8

lacunae

Answer 8

small cavities in the boundaries of lamellae, each containing one osteocyte

Question 9

canaliculi

Answer 9

small channels radiating from each lacuna, connecting the lacunae of adjacent lamellae and ultimately reaching the haversion canal

Question 10

Cell processes extend from _______ into canaliculi, allowing nutrients from the haversion canal to reach the ______.

Answer 10

osteocytes
