It is generally not related to diet and weight, so in many cases the only option for removal is surgery. There are several kinds of cartilage, the commonest and simplest being. Implications for pathology Serosal mesothelium actively participates in various pathological conditions. It is found everywhere in between other tissues in the body, including the nervous system. The connective tissue consists of living cells and extra-cellular matrix. The cartilage and bones form a supporting framework for the body. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue. Reinforcing joints also strengthen and supports the articulations connecting bones. The osseous tissue is relatively hard and lightweight in nature.5. Q.2. 5.Cushioning and insulating. Because of their unique ability to connect and support other tissues/organs in the body, connective tissues are so named. This tissues cells (chondrocytes) are encased in small cavities within the matrix that they secrete. Connective tissues connect and provide support to various structures. There are three types of connective tissues. This shift is an active process, an act of movement by the cells concerned. Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body. In the dense connective tissue, fibroblast cells and fibres are compactly packed. We hope this detailed article on Connective Tissue helps you in your preparation. Adipose (fat) cells are specialized for the storage of energy in the form of triglycerides, but research in the last few decades has shown that fat cells also play a critical role in sensing and responding to changes in systemic energy balance.

DMCA Policy and Compliant. All tissues and organs in the body rely on connective tissue for support, protection, and structure. Based on the cells present and the ECM structure, we differ two types of connective tissue: Connective tissue proper; further divided into loose and dense connective tissues. Male and female reproductive organs can be found in the same plant in flowering plants. Epithelial, connective, muscular, and nerve tissue are the four primary forms of tissue in the body. tissue cushions and protects the tissues it surrounds and provides an (c) The sub-cutaneous adipose tissue acts as shock absorber, e.g. Pigment connective tissues are found in dermis of skin, iris and choroid coat of eye. This tissues cells are specialized in fat storage. It forms layers protecting the body and is therefore, more tightly packed together. Connective tissue is the fundamental tissue that provides structural and mechanical support to other tissues and organs of an animal's body. (3) Vascular Tissues: Vascular tissue includes blood, lymph and the structures in which these fluids are formed, stored and destroyed. Each tissue type has a characteristic role in the body: Epithelium covers the body surface and lines body cavities. Loose fibrous connective tissue: These are fibers that are loosely woven together. Classification of Connective Tissue: A tissue is a clump of cells with similar structures that work together as a unit. connective tissue, group of tissues in the body that maintain the form of the body and its organs and provide cohesion and internal support.

In this manner, irregular dense connective tissue may counterbalance multidirectional pressures, whereas regular dense connective tissue can only do so in one direction (in the sense that its collagen fibers are parallelly orientated). Collagen fibers give other tissues and organs strength and structural support. Helps in connecting different tissues to one another like tendons and ligaments. In adults, most cartilages in vertebrate embryos are replaced by bones. a) In all connective tissues except blood, the cells secrete fibres made up of structural proteins called collagen or elastin.b) They provide strength, elasticity and flexibility to the tissues.C) These are non-living products of the cells, which are of three types, i.e., collagen (white fibres), elastic fibres (yellow fibres) and reticular fibres. Loose and dense irregular connective tissue, formed mainly by fibroblasts and collagen fibers, have an important role in providing a medium for oxygen and nutrients to diffuse from capillaries to cells, and carbon dioxide and waste substances to diffuse from cells .
