The skeletal system quizzes. There are 206 bones in a typical human body, providing a range of important functions : They provide a framework that supports the body. They protect the organs within the body cavities from mechanical injury. They contain and protect the red bone marrow.
- Gross Anatomy of Bone. The structure of a long bone allows for the best visualization of all of the parts of a bone (Figure 1). A long bone has two parts: the diaphysis and the epiphysis.
- Bone Markings. The surface features of bones vary considerably, depending on the function and location in the body. Table 1 describes the bone markings, which are illustrated in (Figure 4).
- Bone Cells and Tissue. Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide a surface for inorganic salt crystals to adhere.
- Compact and Spongy Bone. The differences between compact and spongy bone are best explored via their histology. Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function.
Sep 25, 2024 · Bone tissue (osseous tissue) differs greatly from other tissues in the body. Bone is hard and many of its functions depend on that characteristic hardness. Later discussions in this chapter will show that bone is also dynamic in that its shape adjusts to accommodate stresses.

May 13, 2022 · Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution.
