endosteum
osteon

central canal
osteocyte in lacuna
canaliculus

Volkmann's canal
circumferential lamellae
concentric lamellae

trabecula

Part 2: Skeletal Histology

Obtain the slides listed below that are available for today’s lab.
Focus on each sample and identify the structures listed for each type of tissue.
Indicate the total magnification you make each illustration at in the space provided.
Illustrate each tissue you observe with the microscope at the magnification you listed.
Label each illustration with the structures listed for each.

Compact Bone

Label the tissue with: osteon, concentric lamella, osteocyte in lacuna, central canal, canaliculi
