Function of connective tissue: It binds various tissue together like skin with the muscles and muscles with bones. These fibres are branched and elastic. Question 5: Discuss specialized connective tissue? In the plasma, blood corpuscles float. Highly resistant to one-way traction, dense regular collagenous connective tissue. They always form a network. Connective tissues are most abundant and widely distributed in the body of complex animals that surround many organs. Function of Connective Tissue Connective tissue binds various tissue together and form structural framework for the body Areolar connective tissue serves as a support framework for epithelium Adipose connective tissue store energy as fat, conserve body heat, fills space in the body pads and guards many organs and shape up the body. It is present in the vessels called lymph vessels. Cartilage is a rigid and elastic connective tissue that can resist compression and absorb mechanical stress.

It is composed primarily of connective tissue. i) This tissue consists of star-shaped reticular cells whose protoplasmic process joins to form a cellular network.ii)The reticular cells consist of reticular fibres made up of reticulin protein.iii)This tissue is found in the liver, spleen, lymph nodes, thymus, tonsils, bone marrow and lamina propria of the gut wall.Function: This tissue provides strength and support to many organs. In this tissue, the fibroblasts and collagen fibres are oriented in different patterns.ii. Analytical cookies are used to understand how visitors interact with the website. Adipose tissue is a form of loose connective tissue that is mostly found beneath the skin. Upper eye fat is caused by the accumulation of fat in two compartments over the eyelid. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue. system throughout the body. Adipose connective tissue store energy as fat, conserve body heat, fills space in the body pads and guards many organs and shape up the body. Thus, connective tissue forms one of the four basic types of animal tissues found in the animal body. The adipose tissue stores fat. But opting out of some of these cookies may affect your browsing experience. In human blood, the number of leucocytes fluctuates between 6 and 8 thousand per cubic millimetre. Cells, fibres, and a gel-like material (ground substance) make up connective tissue. This tissues cells (chondrocytes) are encased in small cavities within the matrix that they secrete. Connective tissues are the group of cells that work together to provide support and adhesion in order to form organs. These cookies will be stored in your browser only with your consent. tissue cushions and protects the tissues it surrounds and provides an Areolar and fibrous tissues, both of which are primarily involved with binding components of the animal body, make up connective tissue. What is the main difference between the structure of connective tissue and epithelium? Connective tissue functions to: Provide support for the other basic. What does connective tissue disorder do to your body?Ans: Connective tissue disorder can cause harm to the various types of proteins and the surrounding areas in our body like collagen found in the tendons, ligaments, skin, cartilage and blood vessels. Upper eye fat is caused by the accumulation of fat in two compartments over the eyelid. DMCA Policy and Compliant. 4 What are the types of connective tissue class 9? They release collagen, which helps make up your . e. brain tissue to nervous tissue. It acts as an insulator to help regulate body temperature. Eyeball: Structure and function | Kenhub scattered pigmented macrophages (arrow) in the vitreous; L . The cells of the epithelial tissue are arranged cellular sheets either in single or multiple layers. Areolar Tissue: It is found beneath the skin and helps to sustain the epithelium. Monocytes give rise to macrophages. Additionally, connective tissue stores fat, aids in the movement of nutrients and other substances between tissues and organs, and aids in the repair of injured tissue. A group of identical cells, combined with intercellular chemicals, fulfill a specialized role in multicellular creatures. Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). b. collagens. The reticular cells are phagocytic and form the defence mechanism of the body. Mucoid connective tissue (or Wharton's jelly) is a gelatinous substance that is mostly ground substance (primarily hyaluronic acid and chondroitin sulfate) with a low abundance of collagen or reticular fibers. Bones protect underlying structures from injury. Analytical cookies are used to understand how visitors interact with the website. The word hyaline means glass-like, and hyaline cartilage is a glossy, greyish-white tissue with a uniform appearance. There are weight-bearing limb bones present, such as the long bones of the legs. Functions of Connective Tissue Connective tissue's job is to either connect biological components like bones and muscles together or to hold tissues like muscles, tendons, and even organs in their right location in the body. What are the 4 main functions of connective tissue? stores high-energy molecules, and bones store minerals, such as calcium and Connective tissue disorders are a group of disorders involving the protein-rich connective tissue. Implications for pathology Serosal mesothelium actively participates in various pathological conditions. The primary function of areolar connective tissue is to give nourishment and cushion to the epithelia. Recall that the primary function of plasma cells is antibody secretion, so they are a prominent constituent of loose connective tissue wherever antigens may enter the body, such as the gastrointestinal, urogenital, and respiratory tracts. Passionate, Blogger, Video Creator, Photography. Adipose tissue is a connective tissue that specializes in the synthesis and storage of fat reserves. support Physical and immunologic protection. These cookies ensure basic functionalities and security features of the website, anonymously. Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of amorphous ground substance, and protein fibers. 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.

The connective tissues include several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variantsbone, ligaments, tendons, cartilage, and adipose (fat) tissue. The most abundant and widely distributed tissue in the body is connective tissue. Vitamin C plays a key role in maintaining healthy connective tissue and in accelerating bone repair. Is it easy to get an internship at Microsoft? Your email address will not be published. (c) Reticular fibres. Connective tissue has a wide variety of functions that depend on the types of cells and the different classes of fibers involved. The mesoderm gives rise to the muscle cells and connective tissue in the body. The fibrous components of loose areolar connective tissue, when viewed with the light microscope, appear as colourless strands of varying diameter running in all directions, and, if not under tension, these have a slightly undulant course. These disorders can involve the joints, muscles, skin, the eyes, heart, lungs, kidneys, gastrointestinal tract, and blood vessels. This tissue is present in the skin.Functions: The fibres provide strength to the skin by making it resistant to wear and tear. i. They provide nutritional support by supplying blood to surrounding epithelial tissues such as in areolar connective tissue. c. epithelium and loose connective tissue.
