Cartilage is a form of fibrous connective tissue that is composed of closely packed collagenous fibers in a rubbery gelatinous substance called chondrin. Connective tissue gives shape to organs and holds them in place. For those of you who love all things science and living organisms especially tissues and how stuff works in the human body then this is the quiz for you. It is most widely distributed connective tissue in the animal body. Blood, bone, cartlidge, tendons, ligaments, adipose and lymph. Adipose tissue also produces endocrine hormones that influence activities such as blood clotting, insulin sensitivity, and fat storage. Epithelial tissue (epithelium) functions to line and cover organs as well as carry out absorption and secretion. What parts of the body are classified as connective tissue? P.M. Motta & S. Correr/Science Photo Library/Getty Images. There are many types of connective tissue disorders, such as: Please review the contents of the article and, undifferentiated connective tissue disease, "Mapping the Ligand-binding Sites and Disease-associated Mutations on the Most Abundant Protein in the Human, Type I Collagen", "Monitoring Tissue Engineering Using Magnetic Resonance Imaging", "Metabolic syndrome pathophysiology: The role of adiposetissue", Connective tissue atlas, University of Iowa, https://en.wikipedia.org/w/index.php?title=Connective_tissue&oldid=991316361, Articles needing additional medical references from June 2020, All articles needing additional references, Articles requiring reliable medical sources, Creative Commons Attribution-ShareAlike License, Bind bones and other tissues to each other. 48 Part I: Building Blocks of the Body . [15]:161 Elastic fibers, made from elastin and fibrillin, also provide resistance to stretch forces. Tissues as different as bone and blood are classified as connective tissue. These cells store fat in the form of triglycerides. The Fat Controller: Adipocyte Development. 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 variants— bone , ligaments , tendons , cartilage , and adipose (fat) tissue. Visit each poster and record the description, function, and location in the following chart. cuboidal. Becoming Familiar with Connective Tissues In Part A of this lab you will have the opportunity to familiarize yourself with the different types of connective tissues. Blood also serves to connect other organ systems together by supplying them with nutrients and transporting signal molecules between cells. Extra cellular matrix. number of cell layers and shape of cells. Susumu Nishinaga/Science Photo Library/Getty Images. Dense regular connective tissue, found in structures such as tendons and ligaments, is characterized by collagen fibers arranged in an orderly parallel fashion, giving it tensile strength in one direction. The human body possesses four types of tissues, namely muscle, epithelial, connective and nervous. [15]:158 Cells of the immune system, such as macrophages, mast cells, plasma cells and eosinophils are found scattered in loose connective tissue, providing the ground for starting inflammatory and immune responses upon the detection of antigens.[15]:161. Composition of matrix c. Cell shape d. Both the number of layers and the cell shape 3. All connective tissue consists of three main components: fibers (elastic and collagenous fibers),[1] ground substance and cells. In addition, they perform the work of connecting the body tissue, cell, and organs. This tissue usually derives from the mesoderm, the middle of three layers in an animal embryo. Connective tissue is one of the basic animal tissue. This micrograph shows cancellous (spongy) bone from a vertebra. Bailey, Regina. Adipose tissue gives "mechanical cushioning" to the body, among other functions. Ground substance is a clear, colorless, and viscous fluid containing glycosaminoglycans and proteoglycans to fix the collagen fibers in e intercellular spaces. ThoughtCo, Aug. 27, 2020, thoughtco.com/connective-tissue-anatomy-373207. Lymph is delivered back to blood circulation via lymphatic vessels. Adipocytes appear round and swollen when fat is being stored and shrink as fat is used. They provide nourishment, stability, strength, and support to various organs of the body. They are named connective tissues because of their special function of linking and supporting other tissues/organs of the body. Connective tissue serves to support body parts and bind them together. Plasma is the extracellular matrix of blood with red blood cells, white blood cells, and platelets suspended in the plasma. The blood and lymph vessels are immersed in the connective tissue media of the body. Areolar connective tissue is one of six forms of connective tissue within the body and is named after the airy appearance of the tissue. A.S., Nursing, Chattahoochee Technical College. Loose connective tissue is named so because of the "weave" and type of its constituent fibers. In comparison to loose connective tissue, dense tissue has a higher proportion of collagenous fibers to ground substance. An early scientific classification of tissues divided them on the basis of the organ system of which they formed a part (e.g., nervous tissues). In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue. Responsible for producing connective tissue What parts of the body are classified as connective tissue Blood, bone, cartilage, tendons, ligaments, adipose and lymph "Learn About the Body's Connective Tissue." These cells include fibroblasts, fat cells, mast cells, and also white blood cells like the macrophages, plasma cells, etc. Allow organs like arteries and lungs to recoil, This page was last edited on 29 November 2020, at 12:26. Connective tissue is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. (2020, August 27). This matrix can be liquid or rigid. As the name implies, connective tissue serves a connecting function: It supports and binds other tissues in the body. In addition to connective tissue, other tissue types of the body include: Regina Bailey is a board-certified registered nurse, science writer and educator. Liquid connective tissue (examples of tissue is blood, W.B.C’s, lymph) The connective tissue has different types of cells supporting specialized tissue. There are two types of bone tissue: spongy and compact. Connective tissue is classified into two subtypes: soft and specialized connective tissue. [5][6] Connective tissue proper consists of loose connective tissue and dense connective tissue (which is further subdivided into dense regular and dense irregular connective tissues. Bailey, Regina. The tissue was already recognized as a distinct class in the 18th century.[3][4]. Epithelial tissues—also known as epithelium—form the coverings and linings of surfaces in and on the animal’s body. It includes fibrous tissues, fat, cartilage, bone, bone marrow, and blood. Avascular are made of more extra cellular things. It holds organs in place and attaches epithelial tissue to other underlying tissues. They contain more intercellular substances than the other tissues. Dense regular connective tissue (found in tendons and ligaments) Cartilage (a type of supporting connective tissue that consists of chondrocyte cells, collagen fibers, and elastic fibers; semi-solid or flexible matrix; includes hyaline cartilage, fibrocartilage, and elastic cartilage) Adipose tissue forms an insulating layer under the skin, storing energy in the form of fat. The connective tissue and the epithelium are separated by a basement membrane. Like other connective tissue types, blood is derived from mesoderm, the middle germ layer of developing embryos.
