Cells of the immune system Cells secrete structural proteins known as collagen or elastin in all connective tissues except blood. i) This tissue contains a jelly-like substance called Whartons jelly and some delicate collagen fibres and primitive type of fibroblasts.ii) This tissue occurs as embryonic connective tissue in the foetus and vitreous chamber of the eye.Function: It is involved in the secretion of ground substance and fibres. The adipose tissue acts as a shock absorber around some organs, such as eyeballs and kidneys.7. One major profibrotic factor that promotes excessive ECM accumulation is cellular communication network 2 (CCN2), also known as connective tissue growth factor (CTGF), which is essential for vascular development and the modulation of cell movement [5]. It circulates within the blood vessels of higher animals. Bone, cartilage, fat, blood, and lymphatic tissue are all examples of connective tissue. The cells usually occur in groups of two or four, and they have a tendency for multiplying. It form inter cellular substance between cells of different types of tissue, so that help in friction less movement of the body organ. to bone, and ligaments are connective tissue bands that hold bones together. There is a large central cavity containing bone marrow. When someone starts losing weight, the size of the fat cells decreases or shrinks. Excess nutrients are converted into lipids and stored in this tissue if they are not immediately used. What are 3 general characteristics of connective tissues? i) The irregular pigmented cells (chromatophores or melanophores) contain yellowish-brown, black or blue melanin pigment granules.ii) This tissue is present in the choroid, ciliary body and iris of the eye and dermis of the human skin.Function: It provides colour to the structures. Lacunae are niches that contain bone cells (osteocytes). Passionate, Blogger, Video Creator, Photography. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue. i. Connective tissues can have various levels of vascularity. Areolar and fibrous tissues, both of which are primarily involved with binding components of the animal body, make up connective tissue. Gene mutations or inherited defective genes can cause connective tissue disorders. 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. They include soft connective tissues as well as specialized forms such as cartilage, bone, fat, and blood. 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. What vitamins help connective tissue? (b) Elastic fibres (yellow fibres) are formed of a protein called elastin. It forms layers protecting the body and is therefore, more tightly packed together. A: According to scientists, fat cells never really disappear. b. epithelial tissue to connective tissue. It is a modified areolar tissue whose matrix contains a large number of adipose cells with fibrocytes and macrophages.ii. In species in which there is a marked difference in color between a darkly pigmented animal hemisphere and a non-pigmented or lightly pigmented vegetal hemisphere, it can be noted that . Cells, fibres, and a gel-like material(ground substance) make up connective tissue. connective tissue. 7Protecting. Question 2: What are connective tissues and their types? They always form a network. It gives the skin suppleness and, because it contains multiple types of cells, it aids in the defense against bacteria and other substances, forming a physical and chemical barrier that protects essential organs. Male and female reproductive organs can be found in the same plant in flowering plants. In this tissue, the collagen fibres are present in rows between many parallel bundles of fibres.ii. The adipose tissue stores fat.3. Connective tissue also forms layers that separate tissues and organs. Ground substance of extra cellular may be liquid, gel or solid. All connective tissues originate from the embryonic mesenchyme or mesoderm. The choroid is a dense network of blood vessels and pigmented stroma between the retina and the sclera. Fig: (a) Dense Regular Connective Tissue, (b) Dense Irregular Connective Tissue. It is present in the tip of the nose, outer ear joint, between adjacent bones of the vertebral column, limbs and hand in adults.Bone: It is a hard and rigid connective tissue rich in calcium salts and collagen fibres. They prevent the organs from mechanical shocks. Blood. Transportation of nutrients and metabolites through direct diffusion between organs and connective tissue proper. Q.4. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. However, because this tissue is present in ligaments and capsules, it also serves as structural support for the organs in which it is found. Cartilage is avascular, while dense connective tissue is poorly vascularized. Consuming and utilising food is the process of nutrition. Specialized connective tissues include cartilage, bones, and blood. Reinforcing joints also strengthen and supports the articulations connecting bones. Haematopoiesis- Formation of Blood Corpuscles. Different types of connective tissues include areolar tissue, adipose tissue (fat), blood, bone, and cartilage. It is made up of fibroblasts (cells that make and secrete fibers), macrophages, and mast cells. Upper eye fat is caused by the accumulation of fat in two compartments over the eyelid. . It is the primary tissue that supplies the body with structural support. Another layer of cells called the pigment layer also exists in the epidermis. Consuming and utilising food is the process of nutrition. This indicates tendency to malabsorption and toxins in nutritive zone. By using our site, you Connective tissues 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.

It is made up of bone cells called osteocytes. It consists of a transparent, jelly-like sticky matrix containing numerous fibres and cells and abundant mucin. 1.Enclosing and separating other tissues. Three of the most common are the . The mesenchymal cells have large nuclei which later differentiate to form different cells of connective tissues. The ciliary body is a ring-shaped thickening of tissue inside the eye that divides the posterior chamber from the vitreous body.It contains the ciliary muscle, vessels, and fibrous connective tissue.Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber.The aqueous humor then flows through the pupil into the . the kidneys. Your email address will not be published. It acts as an insulator to help regulate body temperature. The thrombocytes, or blood platelets, are a large number of irregular cells that help in the clotting of blood. The cells of the epithelial tissue are arranged cellular sheets either in single or multiple layers. (b) Oxidation of fat in adepocytes generates heats to regulate body temperature; hence, it is called metabolic reserve bank of the body. Osteoblasts form bone, osteoclasts break down or resorb bone, and osteocytes are mature bone cells. Helps in connecting different tissues to one another like tendons and ligaments. i. This layer gives color to the skin. As well there are fewer collagen fibres in loose connective tissue, which is highly cellular and rich in proteoglycans. The entire cartilage is surrounded by a tough coat of fibrous areolar tissue called perichondrium. It provides immunity to the body, helps in the absorption of fats, maintains the blood volume and keeps the tissue cells moist, etc. Unlike epithelial tissue, which has cells that are closely packed together, connective tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane. It consists of a ground substance or matrix, which is typically composed of an organic matter called chondrin. Keratin waterproofs the skin. 1 What is the function of connective tissues? They . Connective tissues are most abundant and widely distributed in the body of complex animals that surround many organs. The connective tissues perform the following functions: They attach organs and tissues together.
