Which of the following options is correct? It is a modified areolar tissue whose matrix contains a large number of adipose cells with fibrocytes and macrophages.ii. Connective tissue may be defined as an animal tissue that supports, connects, and surrounds organs and other body parts. 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. As the name implies, connective tissue serves a connecting function: It supports and binds other tissues in the body. This cookie is set by GDPR Cookie Consent plugin. The most abundant and widely distributed tissue in the body is connective tissue. Connective tissue also transports nutrients and metabolic wastes from the bloodstream to the tissues to which it clings. Necessary cookies are absolutely essential for the website to function properly. 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. 5 Which connective tissue is classified loose? This website uses cookies to improve your experience while you navigate through the website. (e) Cell debris, microorganisms, and foreign substances are ingested by macrophages (= Histiocytes or Clasmatocytes). They are somewhat less flexible than loose connective tissue. These tissues are arranged in a certain proportion and pattern to form an organ such as the stomach, lung, heart, or kidney. 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. Mucopolysaccharides of numerous types have been identified. It also can work as storage components in adipose tissues and in bones. Helps in connecting different tissues to one another like tendons and ligaments. A very small and long body characterizes the disorder. Connective tissue abnormalities can be caused by gene mutations or inherited faulty genes. In biology, flowering plants are known by the name angiosperms. The choroid supplies nutrition to the posterior layers of the retina. You also have the option to opt-out of these cookies. Pigmented connective tissue Mucoid connective tissue How is blood a specialized connective tissue? It acts as an insulator to help regulate body temperature. The adipose tissue stores fat.

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. Passionate, Blogger, Video Creator, Photography. How many types of connective tissue are there? Bone 4. Implications for pathology Serosal mesothelium actively participates in various pathological conditions. Function. Bones of the skeletal system provide rigid support for the body, and semirigid It is generally not related to diet and weight, so in many cases the only option for removal is surgery. To produce movement, they also interact with the skeletal muscles that are attached to them. Connective tissues can have various levels of vascularity. They include soft connective tissues as well as specialized forms such as cartilage, bone, fat, and blood. sole of feet and palm of hand. Fibres and fibroblasts are found compactly packed in the dense connective tissues.This tissue is of the following two types: i. cartilage and bone. The mesothelial cells are supported by a basal membrane in continuity with a thin layer of richly vascularized loose connective tissue, with lymphatics and fatty tissue, which is called the subserosa. Tissue is a phrase used to describe a group of cells that have a similar form and function. At a syndesmosis joint, the bones are more widely separated but are held together by a narrow band of fibrous connective tissue called a ligament or a wide sheet of connective tissue called an interosseous membrane.

(ii) Connective Tissue cells:The cells are of different types:(a) Fibroblasts produce ECMs structural proteins, i.e., fibrous collagen and elastin, adhesive proteins, i.e., laminin and fibronectin, and ground substance, i.e., glycosaminoglycans, such as hyaluronan and glycoproteins. Tissue made of blood. This tissues cells (chondrocytes) are encased in small cavities within the matrix that they secrete. The Integumentary system has many functions: Protects the body's internal living tissues and organs Protects against invasion by infectious organisms Protects the body from dehydration Protects the body against abrupt changes in temperature Helps dispose of waste materials Acts as a receptor for touch, pressure, pain, heat and cold Connective tissues are most abundant and widely distributed in the body of complex animals that surround many organs. The connective tissue performs the following functions:1. 1.Enclosing and separating other tissues. 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 connective tissues contain three components. Specialised Connective Tissues. It consists of a ground substance or matrix, which is typically composed of an organic matter called chondrin. and blood provide protection against toxins and tissue injury, as well as Adipose tissue, which also belongs to this group, has already been mentioned and will be indelibly remembered by students of gross anatomy as the layer of tissue immediately below the skin. Collagen C contains a number of natural ingredients such as vitamin C, which are proven to support healthy connective tissue. Sheets of connective tissue form capsules around organs, such as the liver and the kidneys. Animal Tissues- The structure of cells varies depending on their role. 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. 1 What is the function of connective tissues? 4 What are the types of connective tissue class 9?
