Each osteon has a central Haversian canal , running parallel to long axis of bone. Bone exerts important functions in the body, such as locomotion, support and protection of soft tissues, calcium and phosphate storage, and harboring of bone marrow [3, 4]. Later discussions in this chapter will show that bone is also dynamic in that its shape adjusts to accommodate stresses. Explain how the structure of compact bone relates to its function. Tendons join muscle to bone and stretch across joints to allow the joint to move. @. Bone Function … It consists of a very hard (virtually solid) mass of bony tissue arranged in concentric layers (Haversian systems). Question: How does the structure of the skeletal muscle help it perform its function? Both are the components of the skeletal system of an organism. Spongy bone tissue does not contain osteons that constitute compact bone tissue. Spongy bone is found throughout the body and in virtually every long bone, short bone and sesamoid or circular bone. Nutrients are provided to bone through blood vessels that are contained within canals in bone. Your bones have 2 types of structure: a dense form called cortical bone and a lattice-like form called spongy bone (also known as cancellous or trabecular bone). Bone stores calcium and phosphorous in the form of hydroxyapatite Ca5(PO4)3(OH) in the concentric rings of lamellae. Both support the functioning of muscles. No. Both provide shape and structure to the organism. The bone stores 99% of the body's calcium and 85% of the phosphorus. From the base of the skull, the spine extends to the pelvis. Circumferential lamellae. Both types are found in most bones. @. Osteon, the chief structural unit of compact (cortical) bone, consisting of concentric bone layers called lamellae, which surround a long hollow passageway, the Haversian canal (named for Clopton Havers, a 17th-century English physician).The Haversian canal contains small blood vessels responsible for the blood supply to osteocytes (individual bone cells). The thick collar of compact bone around the central marrow cavity known as diaphysis, as well as the cartilage that covers the ends, allow long bones to perform their function; s upporting the weight of the body and facilitating movement. Outermost layer; wraps the superficial layer of compact bone; consists of two layers including the fibrous outer layer and cellular inner layer . Isolates bone from surrounding tissues; route for blood and nervous supply; actively participates in bone growth and repair. Interstitial lamellae. Function of synovial joints Such roundish unit is called OSTEON. Sl. Well in a number of ways: 1) A function of bone is calcium storage.. This topic covers the structure and function of bone and cartilage, the type of cells found in these tissues, and how bone and cartilage are formed. We start our section on tissue structure function with bone tissue. Moreover, it is a storehouse of calcium and hosphorus. It is normally found in joints that bear large loads, such as the knee. The bone supports most of the major functions of the arm including lifting and throwing. Compact bone makes up 80 percent of the human skeleton; the remainder is cancellous bone, which has a spongelike appearance with numerous large spaces and is found in the marrow space (medullary cavity) of a bone. Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. Expert Answer . Compact pact bone also stores calcium. Bone tissue consists of two types within the same specific bone, e.g., a vertebra of the spinal column: trabecular (cancellous) and cortical (compact). Similarities between Compact bone and Spongy bone @. Periosteum functions. Previous question Next question Get more help from Chegg . the funny bone. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution. Bones and osteoporosis. Due to the strength of compact bone, its main functions is to support the entire body. Cortical bone forms the hard outside layer of all bones in the body and makes up most of the skull and ribs. Biology Lab 10 - Blood typing Prof. Tanvir How does the bone structure relate to the function of long bones? Objectives. Structure of Bone Tissue. Long bones are designed to provide maximum efficiency for muscle functions such as lifting and rapid movement by serving as levers in the limbs. The bone contains a central medullary cavity that serves as the center for bone marrow production. Bone tissue (osseous tissue) differs greatly from other tissues in the body. Compact bone is the denser, stronger of the two types of bone tissue (Figure 6). Compact bone is made of concentric layers of osteocytes and bony matrix. Compact bone is made up of concentric layers ofosteocytes and bony matrix.Compact bone supports extremities like limbs thereby taking body weight.Com view the full answer. Spongy bone gets its name because, you guessed it, it looks like a sponge and has many porous spaces, whereas compact bone is dense, appearing as if it were 'compacted' together. It is very important to keep the blood level of calcium within a narrow range. I shall attempt to relate my answer to the main classes of compounds I have mentioned earlier: Types of proteins in the membrane: - Glycoproteins which may act as receptors - Intrinsic enzymes organised in a specific manner for efficient catalysis of reactions within the cell - Protein channels to allow ions to pass through - Ligand-gated channels as in the case of Na+ and K+ … structure of animal cells, cell division, mitosis, meiosis). Whereas compact bone tissue forms the outer layer of all bones, spongy bone or cancellous bone forms the inner layer of all bones. It is a long bone since its length is greater as compared to its width. @. Compact bone is the outer, dense layer of our bones, closest to the periosteum and adjacent blood vessels. How does structure relate to function..? There are three types of cells that contribute to bone homeostasis.Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells.
