Explanation Justify reasons for the correct statement: Fibrous are extracellular matrix classified as three types, namely collagen, elastic, and reticular. Collagens are strong, fibrous protein consists of amino acid with elongated fibrils. It functions as extracellular elements in connective tissue and it is characterized as rigid or tendon depends on the degree of mineralization. Option (d) is given as, “collagen fibers” Collagen fiber is a strong protein which functions like extracellular structure. Hence, option (d) is correct. Justify reasons for the incorrect statements: Option (a) is given as, “an abundances of glycosaminoglycan”. Glycosaminoglycan is a linear polysaccharide with repeated disaccharide composed of N-acetyl glucosamine glucuronic acid. It characterizes high polarization, binding and attraction of water molecules. The main function as filling gaps between collagen fibril of the extracellular matrix which plays a major role as a lubricant and shock absorbs...

Summary Introduction

Introduction:

The skeletal system of a human body is a flexible framework consists of bones, ligaments, cartilages from embryonic to childhood development. It functions in body support, protect, movement, electrolyte balance, acid-base balance and blood formation. Bones are also called as connective tissue, which consists of matrix help to harden the tissues by deposition of calcium phosphate and other minerals. Hardening process is termed as calcification or mineralization.

Bones are classified by shape: long, short, irregular, or flat. h. The trabeculae of compact bone are arranged in parallel units along the long axis.

Which is not involved in the process of bone repair following a fracture: A. Fibroblasts produce collagen fibers to connect broken pieces of bone B. A fibrocartilaginous callus serves as a model for new bone growth C. Osteoclasts remove excess bone from the hard callus D. The fracture hematoma reorganizes to form a procallus D.
