Answer (i) Bones have a hard and non-pliable ground substance rich in (1) 'calcium salts' and (2) 'collagen fibres' which give bone its strength. Fat contributes mostly to lipid storage, can serve as insulation from cold temperatures and mechanical injuries, and can be found protecting internal organs such as the kidneys and eye. The ground substance of cartilage is not mineralized but is more like very firm Jello®, making cartilage stiff and incompressible but more flexible and resilient than bone. The external ear contains elastic cartilage. It is transparent, colourless, and fills the spaces between fibres and cells. The lungs and arteries have a layer of elastic connective tissue that allows the stretch and recoil of these organs. Nutrients, salts, and wastes are dissolved in the liquid matrix called plasma and transported through the body. The intercellular material in which the cells and fibers of connective tissue are embedded. This ground substance is usually a fluid, but it can also be mineralized and solid, as in bones. The fibers provide tensile strength, while proteoglycans in the ground substance … The neurocranium and … • Bone is the dynamic tissue so its composition varies according to the regulating factors.• 99% of body calcium, 80% of phosphorus and 65% of sodium and magnesium is reserved in the bone• Calcium is needed for many physiological function so it is tightly regulated at normal level (9-11mg/dl)25/27/2012 … the ground substance & fibers make up the extracellular matrix. Bone tissue formation. Bone is the hardest connective tissue. The distinctive appearance of cartilage is due to the presence of polysaccharides called chondroitin sulfates, which bind with ground substance proteins to form proteoglycans. 3. psychoactive substance. 3 synonyms for ground substance: intercellular substance, matrix, hyaloplasm. Bone is a highly vascularized tissue. The osteoblasts produce and secrete ground substance and collagen fibers that stimulate bone growth. Therefore, the correct answer is option C. 1. The ground substance of cartilage and bone stains yellowish to brownish-red; coarse elastic fibers stains purple. In addition to the organic matrix, an inorganic matrix of calcium phosphate (hydroxyapatite) is deposited along collagen fibers, giving bone rigidity to serve as a framework for the body and as … (iii) (4)'Tight' junctions help to stop substances from leaking across a … Identify and distinguish between the types of connective tissue: loose, dense, cartilage, bone, and blood, Explain the functions of connective tissues, Loose Connective Tissue – large amounts of ground substance and fewer fibers, Dense Connective Tissue – large amounts of fibers and less ground substance, Cartilage – specialized cells called chondrocytes are within the matrix (cartilage cells), Bone – strongest connective tissue with little ground substance, hard matrix of calcium and phosphorous and specialized bone cells called osteocytes, Blood – fluid connective tissue, no fibers – only ground substance (plasma) and cells (red, white, and platelets). Reticular connective tissue—fibers mostly reticular, moderately rich in ground substance, frequently numerous … Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. 7) Periodic Acid-Schiff (PAS: Slides 109 and 110) [Example; Example; Example] Structures rich in glycogen and glycoproteins stain red or purple with this technique. Cartilage occurs where flexibility is required, while bone resists deformation. Ligaments and tendons are made of dense regular connective tissue. n. 1. Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body. In the given diagram of a section of bone tissue, certain parts have been indicated by alphabets. Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. Mucous connective tissue—ground substance especially prominent (umbilical cord). Categories of connective tissue include the following: Loose connective tissue is found between many organs where it acts both to absorb shock and bind tissues together. ... bone, os - rigid connective ... rich in mucopolysaccharide ground substance … Figure 4.7. In some tissues, fibers crisscross and form a mesh. The dermis of the skin is an example of dense irregular connective tissue rich in collagen fibers. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column. Some white blood cells have the ability to cross the endothelial layer that lines blood vessels and enter adjacent tissues. GAGs are polysaccharides that trap water, giving the ground substance a gel-like texture. Of bone tissue consisting of collagen fibers than does loose ground substance of bone is rich in tissue contains more collagen fibers than does connective. Solid ( bone ) be mineralized and solid, as in bones 20System/081-3_HISTO_40X.svs/view.apmlÂ.
