1 The skeletal system is composed Bone
of connective tissue called
2 The thin, fibrous membrane Periosteum
covering the entire bone surface
(except in joints).
3 Bone gets its strength from this Compact Bone
hard, shell-like tissue.
4 The periosteum is formed from Osteons
functional units called________
5 Osteons include layers of tissue Lamellae
(compact bone) called?
6 What is the central cavity in an Haversian Cavity
osteon?
7 What houses the blood supply in Haversian Canal
bones?
8 The Periosteum and Haversial Volkmann's Canals
Canal are connected by another
series of channels called?
9 Blood cells that secrete (produce) Osteoblast
the matrix for bone formation.
10 When bone tissue hardens around Osteocytes
the bone making cells, these cells
are now known as?
11 A cell that makes bone. Osteoblast
12 Gaps in the lamellae are called? Lacunae
13 The space that osteocytes occupy Lacunae
within the bone tissue is called?

14 What are the structures in the Veins, Arteries and Nerves
central canal (Haversian Canal)?
15 Hairlike canals that connect the Canaliculi
lacunae to each other and to the
central canal (Haversian Canal) is
called?
16 A type of bone cell that is Osteoclast
responsible for breaking down
bone is called?
17 A type of bone cell that are flatted Lining cells
osteoblasts that protect the bone
and also help balance calcium
levels.
18 What are the two type of bone Periosteal Cells: External Bone Surface Endosteal
lining cells and their locations? Cells: Lining of Internal Surfaces
19 What are bone cells found in the Osteocytes
lacunae?
20 Mature bone cells that monitors Osteocytes
and maintains the mineralized
bone matrix.
21 Bone stem cells found in the Osteogenic Cells
membranous periosteum and
endosteum.
22 Within the hard outer layer of Trabeculae
bone is the spongy layer (spongy
bone) called?
23 In flat bones the spongy bone is Diploe
called?
24 Every bone has a dense outer Compact Bone
layer that looks smooth and solid
to the naked eye called?
