Gross Anatomy of Bone. ... As a component of the skeletal system, a major function of bone is to assist in movement. In addition to its mechanical functions, the bone is a reservoir for minerals (a "metabolic" function). Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution. The bone contains a central medullary cavity that serves as the center for bone marrow production. How does structure relate to function..? Since it continues throughout life it appears to be important for maintenance of the skeleton, but its exact function remains obscure. It is very important to keep the blood level of calcium within a narrow range. Compact bone is the denser, stronger of the two types of bone tissue (Figure 6). Some joints, such as the knee, also have a meniscus in them. 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]. It is the only bone making up the upper arm. @. Compact bone contains a central canal that runs the length of the bone, often called a Haversian canal. At outer and inner surfaces. Such roundish unit is called OSTEON. Due to the strength of compact bone, its main functions is to support the entire body. The bones typically consist of a long shaft called the diaphysis, and two wider extremities on the ends called epiphyses. There are two types of bones known as compact bone and spongy bone. Explain how the structure of compact bone relates to its function. image source: wikipedia Difference between Compact bone and Spongy bone. Bone tissue consists of two types within the same specific bone, e.g., a vertebra of the spinal column: trabecular (cancellous) and cortical (compact). Question: How does the structure of the skeletal muscle help it perform its function? Being a homophone with the word humorous, the humerus bone has also got an interesting name, i.e. Learn more about the anatomy and function of the epiphysis. 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. Sl. 2) Another function of bone is protection.. Cortical bone forms the hard outside layer of all bones in the body and makes up most of the skull and ribs. Compact bone, also called cortical bone, is the hard, stiff, smooth, thin, white bone tissue that surrounds all bones in the human body. Interstitial lamellae. This is essentially an extra layer of cartilage that aims to provide cushioning within the joint. Spongy bones essentially act as shock absorbers; the human body endures high volumes of impacts each day through movements such as walking, skiing, running and jumping. Circumferential lamellae. We start our section on tissue structure function with bone tissue. The bone supports most of the major functions of the arm including lifting and throwing. Compact bone is made of concentric layers of osteocytes and bony matrix. Spongy bone is found throughout the body and in virtually every long bone, short bone and sesamoid or circular bone. Similarities between Compact bone and Spongy bone @. Each stride and jump sends tiny shock waves through the skeletal system, and spongy bones help to … Well in a number of ways: 1) A function of bone is calcium storage.. Instead, it consists of trabeculae, which are lamellae that are arranged as rods or plates. Function of synovial joints Compact bone is the outer, dense layer of our bones, closest to the periosteum and adjacent blood vessels. Structure and Functions of Bone Tissue. 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). Spongy bone tissue does not contain osteons that constitute compact bone tissue. Both compact bone and spongy bones are structural bones. Haversian canals allow blood vessels and some nerves to reach into the bone. Both types are found in most bones. How does the structure of bone-related to its function? Compact bone tissue forms the outer shell of bones. 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. Bone Function … If blood calcium gets too high or too low, the muscles and nerves will not function. From the base of the skull, the spine extends to the pelvis. It is a long bone since its length is greater as compared to its width. Bone stores calcium and phosphorous in the form of hydroxyapatite Ca5(PO4)3(OH) in the concentric rings of lamellae. Compact bone is laid in such a manner that there are histological units seen in cross section. There are two types of bone tissue: compact and spongy.The names imply that the two types differ in density, or how tightly the tissue is packed together. @. (A fracture is a complete or partial break in a bone). It consists of a very hard (virtually solid) mass of bony tissue arranged in concentric layers (Haversian systems). Outermost layer; wraps the superficial layer of compact bone; consists of two layers including the fibrous outer layer and cellular inner layer . Bones work in concert with tendons, joints, ligaments, and skeletal muscles to produce various movements. 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+ … 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.
