Which of the following characteristics applies to the cells known as osteoclasts?

We’ll start with bone tissue in our section on tissue structure and function. This is due to two factors: 1) Bone has traditionally been the most studied tissue mechanically, and 2) because of 1) and bone’s simpler behavior relative to soft tissues, more is understood about bone mechanics in relation to its structure. Bone is a good place to start because it exemplifies the concept of hierarchical structure function, which is present in all biological tissues. The anatomy and structure of bone tissue are illustrated in this section as a foundation for studying tissue structure function and mechanically mediated tissue adaptation. The hierarchical levels of bone structure (anatomy) are defined first, followed by how these levels are built by bone cells removing and adding matrix (physiology). The linear elastic properties of bone are then discussed, as well as how the structure of bone (especially trabecular bone) has been linked to its mechanical function as described by constitutive models.

In the development of bones, the cell organelles that synthesize organic matrix substances are: The endoplasmic reticulum and ribosomes are cell organelles that synthesize organic matrix substances in bone formation. The osteon, or haversian, mechanism transports nutrients to bone cells while also removing waste.
The patella can be easily differentiated when the knee is flexed False. The patella (kneecap) is the largest sesamoid bone and one of the few that appears in the human skeleton on a regular basis. (032018, Patton)
None of the following is not a diaphysis characteristic? Provides a bulbous shape for muscle attachment. The diaphysis’ hollow, cylindrical form and dense, compact bone make it well suited to its role of providing solid support without adding weight. (032018, Patton)
Osteoclasts are the cells responsible for the active erosion of bone minerals. Osteoclasts are multinucleated giant cells that actively erode bone minerals. They are made up of a large number of mitochondria and lysosomes and are created by the fusion of many precursor cells (Patton, 032018).

Overview of Bone Structure The precise composition or organization of individual bone components varies depending on the form of bone and stage of maturation. The same basic elements make up all human bones:
Some bones (such as the frontal and parietal bones) are derived from the neural crest and undergo membranous ossification, while others (such as the sphenoid and occipital bones) are derived from the paraxial mesoderm and undergo endochondral ossification. Bone maturation stages During embryonic development or bone healing, bones are woven together to form primary bone. Via continuous remodeling, the structure of woven bone is disorganized and transformed into ordered tissue of lamellar bone (secondary bone).
The orientation of collagen fibers in the extracellular matrix of immature woven bone and mature lamellar bone is a key distinguishing feature. Bone trabecular (spongy or cancellous bone)
Remodeling and healing of the bones
The human skeleton is constantly changing and remodeling. This is true not only for the replacement of immature woven bone with lamellar bone, but also for the adaptation of adult bones to their specific loads. Remodeling of the bones 
Mast cell meaning, definition & explanation
An osteoclast is a type of bone cell that breaks down bone tissue (from Ancient Greek (osteon) ‘bone’ and (clastos) ‘broken’). The care, repair, and remodelling of vertebral skeleton bones rely on this feature. By secreting acid and a collagenase, the osteoclast disassembles and digests the composite of hydrated protein and mineral at a molecular level, a mechanism known as bone resorption. This mechanism also aids in the regulation of blood calcium levels.
An osteoclast is a large multinucleated cell with five nuclei and a diameter of 150–200 m. Human osteoclasts on bone have five nuclei and a diameter of 150–200 m. When osteoclast-inducing cytokines are used to transform macrophages to osteoclasts, very large cells with diameters of up to 100 m result. Because of the non-natural substrate, these cells can have thousands of nuclei and normally express major osteoclast proteins, but they differ significantly from cells in living bone. (5) [number six] The multinucleated assembled osteoclast’s size enables it to concentrate several macrophages’ ion transfer, protein secretory, and vesicular transport capabilities on a small area of bone.
