Structure of long bone (ESG8C) Although there are many different types of bones in the skeleton, we will discuss the different parts of a specific type of bone: the long bone. The differences between compact and spongy bone are best explored via their histology. 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. 0 % Time .

Four types of cells are found within bone tissue: osteoblasts, osteocytes, osteogenic cells, and osteoclasts (Figure 5). Tendons and ligaments also attach to bones at the periosteum. Parts of the Skeletal System (Source: Britannica) The skeletal system is made up of bones and cartilage. They make up part of the growth plate, and during childhood, cells in the metaphysis divide for longitudinal bone growth. This is an online quiz called Long Bone Anatomy. Cellular Structure of Long Bone Compact bone The hard outer layer of bones is composed of compact bone tissue, so-called due to its minimal gaps and spaces. Each osteocyte is located in a space called a lacuna and is surrounded by bone tissue. It is important for bones to be strong to support our body weight. This is an online quiz called Label the Long Bone. Spongy bone is composed of trabeculae that contain the osteocytes. It provides protection for places outside a soft structure, such as in the flat bones of the skull. Flat bones, like those of the cranium, consist of a layer of diploë (spongy bone), lined on either side by a layer of compact bone (Figure 3). Examples of long bones include the femur, tibia, radius and ulna. Epiphyseal plates Space occupied by red marrow endo am Figure 122 Label the features associated with the microscopic structure of bone. Bone scans are also useful. Start studying LABEL: Structure of a Long Bone. structure of a long bone Long bone: elongated bone consisting of a body (diaphysis) and two terminal parts (epiphyses), such as the leg and arm bones (femur, radius, phalanges and others). Though different long bones have different shapes and functions, they all have the same general structure. 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. In a long bone, the stress is best absorbed along the longitudinal axis of the diaphysis. These include the periosteum, compact bone, spongy bone and an inner core of bone marrow. Learn vocabulary, terms, and more with flashcards, games, and other study tools. What do we mean by an 'articulation'? A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3.1). Label the Parts of a Long Bone. The answer lies in the properties of a third category of bone cells—the osteogenic cell. Bones of the Skeleton - Science Quiz: The collection of bones in the human body is called the skeletal system. Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. Get more help from Chegg. Figure 121 Label the major structures of this long bone (femur). The periosteum forms the outer surface of bone, and the endosteum lines the medullary cavity. 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 usually occurs in adults over age 40.

The outer surface of the bone is covered with a fibrous membrane called the periosteum (peri– = “around” or “surrounding”). It can be found under the periosteum and in the diaphyses of long bones, where it provides support and protection. Observe The Individual Bone Specimens And Arrange Them Into Groups According To The Following Shapes And Examples: Long … Paget’s disease is diagnosed via imaging studies and lab tests.

The metaphyses are also important for bone growth during childhood and adolescence. the tough membrane covering the shaft of the bone. Bones of the pelvis, skull, spine, and legs are the most commonly affected. As with the other markings, their size and shape reflect the size of the vessels and nerves that penetrate the bone at these points. 27. Here we explain the anatomy of bone and the function of each part. Red marrow fills the spaces in some bones. Though different long bones have different shapes and functions, they all have the same general structure. Figure 2. Periosteum and Endosteum. Osteoblasts, which do not divide, synthesize and secrete the collagen matrix and calcium salts. The femur, tibia and fibula in the leg, and the humerus, radius and ulna in the arm are all examples of long bones. Blood vessels and nerves enter the bone through the nutrient foramen. 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. Part A. The structure of a long bone allows for the best visualization of all of the parts of a bone ().A long bone has two parts: the diaphysis and the epiphysis.The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The largest part of any long bone is the long cylindrical middle, called the diaphysis. Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). Bone is hard and many of its functions depend on that characteristic hardness. This system allows nutrients to be transported to the osteocytes and wastes to be removed from them. The skeleton is the central structure of the body and is made up of bones, joints and cartilage. Drag the labels to identify the structures of a long bone. She holds master's degrees in French literature and education. Figure 6.24: Parts of a long bone. Saved by Monique Wilson. While some people with Paget’s disease have no symptoms, others experience pain, bone fractures, and bone deformities (Figure 8). These are strong bones because they must be able to withstand the force generated when the body moves and changes direction. The cell responsible for bone resorption, or breakdown, is the osteoclast. 0. Osteogenic cells are undifferentiated and develop into osteoblasts. The arrow in the figure is pointing to which of the following structures? Start studying Anatomy H: Chapter 6, know labeling for long bone and the skeleton. A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3.1). Each consecutive bone lamella has collagen fibers that wrap in alternating directions. Structure. The two main parts of the skeletal system, as mentioned above, are bones and cartilage. 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. The main feature of compact bone is its strength. The osteocytes are located inside spaces called lacunae (singular = lacuna), found at the borders of adjacent lamellae. This cross-section of a flat bone shows the spongy bone (diploë) lined on either side by a layer of compact bone. Compact bone also supports the stress placed on it. In general, their size and shape is an indication of the forces exerted through the attachment to the bone. 3 Differentiate the special characteristics of compact bone tissue. 8 ) used in the diaphyses of long bones have a long bone spongy!
