X-rays may show bone deformities or areas of bone resorption. Flashcards, matching, concentration, and word search. Figure 7. (the only examples are on the femur. Osteocytes maintain the mineral concentration of the matrix via the secretion of enzymes. The osteoblast. The osteocytes are located inside spaces called lacunae (singular = lacuna), found at the borders of adjacent lamellae. When osteoblasts get trapped within the calcified matrix, their structure and function changes, and they become osteocytes. Composed predominately of compact bone. Table 2 reviews the bone cells, their functions, and locations. hornets12. Diagram of Blood and Nerve Supply to Bone. Figure 4. Pick an audience - or yourself - and it'll end up in their play queue. The Chemical Level of Organization, 2.1 Elements and Atoms: The Building Blocks of Matter, 2.4 Inorganic Compounds Essential to Human Functioning, 2.5 Organic Compounds Essential to Human Functioning, Chapter 3. The differences between compact and spongy bone are best explored via their histology.

Immature osteogenic cells are found in the deep layers of the periosteum and the marrow. There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. These are where other structures like muscles, blood vessels and nerves, or other bones are attached to or articulate with or travel through the bone. The osteocytes in spongy bone are nourished by blood vessels of the periosteum that penetrate spongy bone and blood that circulates in the marrow cavities. The Cellular Level of Organization, 3.2 The Cytoplasm and Cellular Organelles, Chapter 4. These vessels and nerves branch off at right angles through a perforating canal, also known as Volkmann’s canals, to extend to the periosteum and endosteum.

The expanded articular end of an epiphysis, often separated from the shaft by a narrower neck B. Each epiphysis meets the diaphysis at the metaphysis, the narrow area that contains the epiphyseal plate (growth plate), a layer of hyaline (transparent) cartilage in a growing bone. The medullary cavity has a delicate membranous lining called the endosteum (end– = “inside”; oste– = “bone”), where bone growth, repair, and remodeling occur. Foramen (holes through which blood vessels can pass through), Deep layers of the periosteum and the marrow, Growing portions of bone, including periosteum and endosteum, Bone surfaces and at sites of old, injured, or unneeded bone, Identify the anatomical features of a bone, Define and list examples of bone markings, Compare and contrast compact and spongy bone, Identify the structures that compose compact and spongy bone, Describe how bones are nourished and innervated. An Introduction to the Human Body, 1.2 Structural Organization of the Human Body, Chapter 2. Spongy bone is composed of trabeculae that contain the osteocytes. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution. Paget’s disease is diagnosed via imaging studies and lab tests. However, in a small percentage of cases, bisphosphonates themselves have been linked to an increased risk of fractures because the old bone that is left after bisphosphonates are administered becomes worn out and brittle.

They differentiate and develop into osteoblasts.

large rounded projection, may be roughened. In these studies, a dye containing a radioactive ion is injected into the body. The periosteum covers the entire outer surface except where the epiphyses meet other bones to form joints (Figure 2). A projection is an area of a bone that projects above the surface of the bone. This quiz has tags.

This cross-section of a flat bone shows the spongy bone (diploë) lined on either side by a layer of compact bone. This activity was created by a Quia Web subscriber. … An activity to help in learning the names of the projections, openings, and depressions in the bones of the human body. These salt crystals form when calcium phosphate and calcium carbonate combine to create hydroxyapatite, which incorporates other inorganic salts like magnesium hydroxide, fluoride, and sulfate as it crystallizes, or calcifies, on the collagen fibers. Bone Markings. If osteoblasts and osteocytes are incapable of mitosis, then how are they replenished when old ones die? This system allows nutrients to be transported to the osteocytes and wastes to be removed from them. Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. Java Games: Flashcards, matching, concentration, and word search. The surface features of bones vary considerably, depending on the function and location in the body. 31s.

Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). Match Game Times. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The hyoid serves as the base for the tongue above, and is attached to the larynx below and the pharynx posteriorly.

Four types of cells are found within bone tissue. armlike bar of bone: Sinus: space within a bone, filled with air and lined with mucus membrane: Meatus: canal-like passageway: Fossa: shallow, basinlike depression in a bone, often serving as an articular surface: Fissure: narrow, slitlike opening: Foramen: round or oval opening through a bone The spaces of the trabeculated network provide balance to the dense and heavy compact bone by making bones lighter so that muscles can move them more easily. Give it a try! More. Start studying Bone Markings Matching- Anatomy and Physiology. Java Games: Flashcards, matching, concentration, and word search. Students, teachers and rockstars alike all come here to create and learn.

Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles.
