Know the classification of bones: long, short, flat, irregular, sutural (wormian) and sesamoid, and examples of each. Where do sesamoid bones form, and what do they do?
Know the parts of the long bones -diaphysis, epiphysis, periosteum, marrow (medullary) cavity, etc .
Know what a tuberosity, crest, meatus, sinus, foramen, head and condyle mean for bones. Know the terms in table 9.1 in your lab manual.
What are the four types of bone cells, and which one comes from a difference source? What is that source? What does each type of bone cell do? How are osteocytes connected to each other, and why is this important?
What are the organic and inorganic components of the matrix of bone? How do they each function?
What is the microscopic structure of compact bone? What is found in the central canal?    How do the collagen fibers differ in alternating lamellae, and what does this do for the bone?
How does the microscopic structure of spongy bone differ from that of compact bone? (hint: what is missing?) How do the osteocytes here get nutrients?

When would we find red marrow in the marrow cavity? Yellow marrow? What does red marrow do? Where would you obtain bone marrow for donation purposes? What is diploe?
