Figure 5. The Most Misspelled Word In The English Langauge 10p Multiple-Choice. This cross-section of a flat bone shows the spongy bone (diploë) lined on either side by a layer of compact bone.
Figure 4. Bisphosphonates, drugs that decrease the activity of osteoclasts, are often used in the treatment of Paget’s disease. 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. Bone is hard and many of its functions depend on that characteristic hardness. In addition, the spaces in some spongy bones contain red marrow, protected by the trabeculae, where hematopoiesis occurs. large rounded projection, may be roughened. Paget’s disease is diagnosed via imaging studies and lab tests. Figure 6.6 Illustrations of more bone markings. Match Game Times. As with the other markings, their size and shape reflect the size of the vessels and nerves that penetrate the bone at these points. Red marrow fills the spaces in some bones.
Red marrow fills the spaces in the spongy bone. ), Narrow ridge of bone; less prominent than a crest, Epicondyle (ligament & muscle attachment), Raised area on or above a condyle- next to the joint where muscles & ligaments attach, Head (projections that help to form joints), Facet (projections that help to form joints), Condyle (projections that help to form joints), Space w/in a bone, filled with air & lined w/ mucous membrane, Shallow, basinlike depression in a bone, often serving as an articular surface.

The osteocytes are located inside spaces called lacunae (singular = lacuna), found at the borders of adjacent lamellae. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow. A hole is an opening or groove in the bone that allows blood vessels and nerves to enter the bone. A narrower connection between the epiphysis and diaphysis C. A small, flat articular surface D. A smooth, rounded articular process E. A smooth, grooved articular process shaped like a pulley Table 1 describes the bone markings, which are illustrated in (Figure 4). Longer than they are wide, generally consisting of a shaft w/ heads at either end. Most bones have some combination of bumps, ridges, projections, depressions, cavities, and holes in them that help them carry out their functions. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone. Table 7.2 describes the bone markings, which are illustrated in (Figure 7.2.1).There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. (Micrograph provided by the Regents of University of Michigan Medical School © 2012). It can be found under the periosteum and in the diaphyses of long bones, where it provides support and protection. A shoutout is a way to let people know of a game. Compact bone is the denser, stronger of the two types of bone tissue (Figure 6). Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. Bone Markings. The surface features of bones vary considerably, depending on the function and location in the body. Immature osteogenic cells are found in the deep layers of the periosteum and the marrow. Start studying Bone Markings Matching. Students, teachers and rockstars alike all come here to create and learn.
The differences between compact and spongy bone are best explored via their histology.
When occurring in the skull, Paget’s disease can cause headaches and hearing loss. Learn while having fun by playing the Bones and Bone Markings matching game The instructor will provide you with several bones from the human body.
In addition to the blood vessels, nerves follow the same paths into the bone where they tend to concentrate in the more metabolically active regions of the bone. As the secreted matrix surrounding the osteoblast calcifies, the osteoblast become trapped within it; as a result, it changes in structure and becomes an osteocyte, the primary cell of mature bone and the most common type of bone cell. The surface features of bones vary considerably, depending on the function and location in the body.
Short bones formed in thendons (patellas). 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 only examples are on the femur. An interactive quiz covering Humerus Bone through multiple-choice questions and featuring the iconic GBS illustrations.
There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. start High Scores. 25 Cities of the USA 25p Image Quiz.
Table 7.2 describes the bone markings, which are illustrated in (Figure 7.2.1). Bone scans are also useful. They can communicate with each other and receive nutrients via long cytoplasmic processes that extend through canaliculi (singular = canaliculus), channels within the bone matrix.
When the bone stops growing in early adulthood (approximately 18–21 years), the cartilage is replaced by osseous tissue and the epiphyseal plate becomes an epiphyseal line. As the blood passes through the marrow cavities, it is collected by veins, which then pass out of the bone through the foramina.
In general, their size and shape is an indication of the forces exerted through the attachment to the bone. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) (Figure 7). In general, their size and shape is an indication of the forces exerted through the attachment to the bone.
Collectively, these kinds of features are called markings.
They are used by clinicians and surgeons, especially orthopedists, radiologists, forensic scientists, detectives, osteologists, and anatomists. 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. Some scientists believe Paget’s disease is due to an as-yet-unidentified virus. Tendons and ligaments also attach to bones at the periosteum.
The periosteum covers the entire outer surface except where the epiphyses meet other bones to form joints (Figure 2). LM × 40. Composed predominately of compact bone. 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.

Areas of bone resorption have an affinity for the ion, so they will light up on the scan if the ions are absorbed. Figure 6. Generally thin, w/ two waferlike layers of compact bone sandwiching a layer of spongy bone between them. Next … 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. The outer surface of the bone is covered with a fibrous membrane called the periosteum (peri– = “around” or “surrounding”).
