The orientation of fibers produces a regular or irregular pattern, resulting in dense regular and dense irregular tissues. Q.4. Privacy Policy, They . 1 What is the function of connective tissues? In this article we will discuss about the function of connective tissue. To produce movement, they also interact with the skeletal muscles that are attached to them. 5.Cushioning and insulating. Bone marrow forms a source of blood corpuscles.9. These fibres are delicate, branched and inelastic. I have been asked this question in an interview for internship. These fibres occur in bundles. In biology, flowering plants are known by the name angiosperms. This tissues cells are specialized in fat storage. 5 What are the function S of fat in cheeks and behind the eyes? Ground substance of extra cellular may be liquid, gel or solid. Another vital nutrient that helps to support healthy connective tissue is . Tendons, which connect skeletal muscles to bones, and ligaments, which connect two bones, are examples of this tissue.Dense irregular connective tissue contains fibroblasts and many fibers (mainly collagen) that are orientated in diverse directions. In response to cold or stress, your fingers or toes might turn white and then purplish blue. Plants are necessary for all life on earth, whether directly or indirectly. Q.3. As the name implies, regular elastic dense connective tissue provides elastic characteristics to the organ in which it is found, allowing it to stretch and generate a certain degree of flexion when coupled with rigid parts. Question 2: What are connective tissues and their types? The total choroidal blood supply far exceeds the need for retinal nutrition, and it also may serve as a heat exchange mechanism to prevent the retina from overheating. (g) Mesenchyme cells give rise to different types of cells of connective tissue. Pigment connective tissue is partly built up of stellate, serrated or lobular pigment cells of ectodermal origin, melanocytes. Upper eye fat is caused by the accumulation of fat in two compartments over the eyelid. Three types of connective tissues can be distinguished depending on the composition of the ground substance:(1) Connective tissue proper(2) Skeletal tissues(3) Vascular tissues. Sheets of connective tissue form capsules around organs, such as the liver and The flower is the sexual reproduction organ. It is composed primarily of connective tissue. Most connective tissues have a good blood supply but some do not. The human body is made up of billions of cells that work together to execute numerous jobs. Cartilage, bones, and blood are examples of specialized connective tissues. It is also known as the fibrous tunic. The major function of this system is as a barrier against the external environment. There is a large central cavity containing bone marrow. Solve any question of Structural Organisation In Animals with:- Patterns of problems > Collagen C contains a number of natural ingredients such as vitamin C, which are proven to support healthy connective tissue. What is the function of connective tissue class 9? The blood and the cells that make it up. i) These tissues form the endoskeleton of the vertebrates that form a rigid framework that supports the body.ii) It also protects the vital organs and helps in locomotion.iii) There are two types of skeletal tissues:Cartilage: It is a tough, semi-transparent, elastic and flexible tissue formed up of cartilage cells called chondrocytes. Woven Bone is composed of mineralized tissues called bone. 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. If you get stuck do let us know in the comments section below and we will get back to you at the earliest. 1 The thickness of this subcutaneous layer varies throughout the body and also from person to person. It also can work as storage components in adipose tissues and in bones. Rajkumar is a lecturer from TamilNadu, India. It contains high quantities of water, several types of cells, and a fibrous extracellular matrix. Because of their unique ability to connect and support other tissues/organs in the body, connective tissues are so named.

Orbicularis oris muscle, also known as musculus orbicularis oris is a complex, multi-layered muscle which attaches through a thin, superficial musculoaponeurotic system to the dermis of the upper lip and lower lip and serves as an attachment site for many other facial muscles around the oral region. Connective tissue performs the following major functions: 1.Enclosing and separating other tissues. Lymph fluid is also make of plasma and is filled with white blood cells, or leukocytes. 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. Connective tissues with special characteristics of structure and function include elastic, reticular, and pigmented types. Fibres, fibroblasts, mast cells, chromatocytes, adipocytes, and macrophages are spread irregularly. You also have the option to opt-out of these cookies. d. muscle tissue to nervous tissue.

(B) Adipose Tissue: It is a fat storing connective tissue. The cartilage and bones form a supporting framework for the body.4. The names allude to the fact that the two varieties differ in density or how closely the tissue is packed together. 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.
