What are two names of bone tissues?
Compact Bone, makes up the dense material in a long section of a bone. Cancellous bone, is found in the end regions of long bones and hs plates of bone interspersed with bone marrow.
What does the medullary cavity do in the bone?

What is the difference between compact bone and spongy bone and where are they found?
The middle section of a long bone is compact or 'solid'. Of course, this bone is not completely solid . . . there are 3 kinds of living bone cells located there: Osteoblasts, which grow new bone, Osteoclasts, which remove bone for use elsewhere in the body, and osteocytes, which are simply living cells within the bone. Near the ends of the long bones, though, is bone that has zillions of little 'bubbles' of bone . . . it does look a little like a sponge, but it is hard. The spongy bone is near the part that grows when you are young. Later in life the spongy bone helps cushion sharp impacts to the bone ends.
Yolanda is asked to review a bone slide that has been set up under a microscope She sees concentric layers surroundings a central cavity or canal Is this bone section taken from the diaphysis or the?
Yolanda is likely reviewing a bone section from the diaphysis, which is the shaft of a long bone. The concentric layers surrounding a central cavity or canal are characteristic of compact bone tissue, which is typically found in the diaphysis of long bones.
What type of bone has lacunae in concentric circles around central canals and is found on the wall of the middle prtion of the long bone?
The type of bone you are referring to is compact bone. It contains osteocytes housed in lacunae arranged in concentric circles called lamellae around central canals (Haversian canals). Compact bone is found on the outer wall of the middle portion of long bones.
