Specialised Connective Tissues. Vitamin C plays a key role in maintaining healthy connective tissue and in accelerating bone repair. Upper eye fat is caused by the accumulation of fat in two compartments over the eyelid. 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).

The connective tissues contain three components. It consists of a transparent, jelly-like sticky matrix containing numerous fibres and cells and abundant mucin. Give two examples.Ans: Bone, ligaments, tendons, cartilage, and adipose (fat) tissue are all kinds of connective tissue that differ only in density and cellularity, as well as more specialised and recognised varieties like bone ligaments, tendons, cartilage, and adipose (fat) tissue. This tissues cells (chondrocytes) are encased in small cavities within the matrix that they secrete. The connective tissues are made up of the following three components: a) It is a clear and viscous substance whose consistency varies from liquid (e.g., blood) to semisolid (e.g., cartilage) and solid (e.g., bone) form. The Leaf:Students who want to understand everything about the leaf can check out the detailed explanation provided by Embibe experts. Connective tissue is made up of cells, fibers, and a gel-like substance. The symptoms of this disorder include widespread muscle pain and tenderness. The names allude to the fact that the two varieties differ in density or how closely the tissue is packed together. Question 4: In what tissue collagen fiber is present? It connects various tissues or organs and provides support to various structures of an animal body. They can be found all over the body. The cookie is used to store the user consent for the cookies in the category "Other. Fig: Specialised Connective Tissues: (a) Cartilage, (b) Bone, (C) Blood. 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 organs also help in defence. The epidermis contains the pigment melanin which gives us our skin tone.

Male and female reproductive organs can be found in the same plant in flowering plants. The presence of thick regular elastic connective tissue in big blood arteries allows tension to build up in the vessel wall during cardiac systolic ejection, and the release of this tension keeps vascular blood flow going during the diastole phase. Monocytes give rise to macrophages. Necessary cookies are absolutely essential for the website to function properly. Loose connective tissues can be found all over the body, providing both support and elasticity. It is most widely distributed connective tissue in the animal body. Salts and fibres may be found in the intercellular matrix, which is unique to a particular tissue and gives it distinct features. The adipose tissue is made up primarily of lipids and/or fats. 6.Transporting. 2.Connecting tissues to one another. The cells usually occur in groups of two or four, and they have a tendency for multiplying. The hard part of the bone is called the ground substance or matrix, and it always contains calcium phosphate.

In this article we will discuss about the function of connective tissue. Responds immediately to epithelial damage or antigen interaction. These are connective and support tissues that have no other purpose except to fill the body. Increasing evidence demonstrates that, beyond supplying nutrients to the outer retina, the different choroidal cells contribute to the retina's homeostasis, especially by paracrine signaling. Bones protect underlying structures from injury. Fibromyalgia is one of a group of chronic pain disorders that affect connective tissues, including the muscles, ligaments (the tough bands of tissue that bind together the ends of bones), and tendons (which attach muscles to bones). The cells of this tissue are specialised to store fats.iii. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. 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. The term connective tissue was introduced by J.P. Muller in \(1830.\). Connective tissue also transports nutrients and metabolic wastes from the bloodstream to the tissues to which it clings. Blood connective tissue function is to provide oxygen and nutrients to cells and remove waste. The choroid is a dense network of blood vessels and pigmented stroma between the retina and the sclera. (h) Chromatocytes (Pigment cells) are found in the dermis of the skin to impart colour to the animal.
