PRESENTED BY: 1. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution.Compact bone is the denser, stronger of the two types of bone tissue (Figure 6.10). Generally speaking these bones protect, support, or … Their shapes and their functions are related such that each categorical shape of bone has a distinct function. Flashcards. Many facial bones, particularly the ones containing sinuses, are classified as irregular bones. 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. Red marrow fills the spaces in the spongy bone. Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function.
Key Concepts: Terms in this set (22) Long Bone-made up of compact bone-may have large amount of spongy bone at the ends or extremities. Each epiphysis meets the diaphysis at the metaphysis, the narrow area that contains the The medullary cavity has a delicate membranous lining called the 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. A long bone has two parts: the The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone. OUTLINE •Introduction.
Spell. Match. The four principal types of bones are long, short, flat and irregular. The vertebrae and some of the bones in the All bones have surface markings and characteristics that make a specific bone unique. A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed. Classification of Bones. Classification of Bones- according to the ossification Membranous bones: bones are formed by intramembranous ossification, they ossify in mesenchymal condensation. They are primarily Short bones are roughly cube shaped with vertical and Flat bones are thin, flattened, and usually curved. This system allows nutrients to be transported to the osteocytes and wastes to be removed from them. CLASSIFICATION OF BONES PRESENTATION DPT Batch# 01 GROUP # 03(C) 2. It can be found under the periosteum and in the diaphyses of long bones, where it provides support and protection.The microscopic structural unit of compact bone is called an The osteocytes are located inside spaces called lacunae (singular = lacuna), found at the borders of adjacent lamellae. Classification of Bones. Most of the bones of the Bones that are not in any of the above three categories are classified as irregular bones. Saadiya Naeemi. It is found in the interior of normal bone. The 206 bones that compose the adult skeleton are divided into five categories based on their shapes (Figure 6.6). They consist of a long shaft with two bulky ends or extremities. Created by. Write. Long bones, 2. justind024. bones of vault of skull ( parietal, frontal & occipital) and bones of face. The cell responsible for bone resorption, or breakdown, is the The differences between compact and spongy bone are best explored via their histology. •Types Of Bones: A.Types of bone on the basis of shape: 1. Gravity. Short Bone-roughly cube-shaped -consisting primarily of … Test. Bones are composed of two types of tissue: 1. Classification of Bones There are two basic types of B one tissue. The four principal types of bones are long, short, flat and irregular. e.g. They consist of a long shaft with two bulky ends or extremities.
