This image shows a sample of fat tissue with fat cells (adipocytes, blue) surrounded by fine strands of supportive connective tissue. Connective tissue is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. Epithelial tissues act as coverings, controlling the movement of materials across their surface. Calcium phosphate gives bone its firmness. The three types of connective tissue found in the human body are (1) dense regular, (2) dense irregular, and (3) loose irregular (Table 2-1). Cancellous bone is characterized by a honeycomb arrangement, comprising a network of trabeculae (rod-shaped tissue). [9] Fibroareolar tissue is a mix of fibrous and areolar tissue. What parts of the body are classified as connective tissue? Like cubes c. Thin and flat d. All of the above 2. Epithelium also lines the large internal body … Ground substance is a clear, colorless, and viscous fluid containing glycosaminoglycans and proteoglycans to fix the collagen fibers in e intercellular spaces. It holds organs in place and attaches epithelial tissue to other underlying tissues. Responsible for producing connective tissue What parts of the body are classified as connective tissue Blood, bone, cartilage, tendons, ligaments, adipose and lymph Adipose tissue gives "mechanical cushioning" to the body, among other functions. In addition to connective tissue, other tissue types of the body include: Regina Bailey is a board-certified registered nurse, science writer and educator. All connective tissue consists of three main components: fibers (elastic and collagenous fibers), ground sub… cuboidal. Number of layers b. Loose areolar connective tissue Epithelium (/ ˌ ɛ p ɪ ˈ θ iː l i ə m /) is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue.It is a thin, continuous, protective layer of cells.Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An animal body is made of four different types of tissues. In vertebrates, the most common type of connective tissue is loose connective tissue. The six types of connective tissue are bones, cartilage, and loose connective tissue, and adipose tissue, dense regular and … The term "connective tissue" (in German, Bindegewebe) was introduced in 1830 by Johannes Peter Müller. Connective tissue, group of tissues in the body that maintain the form of the body and its organs and provide cohesion and internal support. Connective tissue that provides support and framework for the body consists of fibrous proteins and nonfibrous ground substance in varying proportions depending on their functions. In addition, they perform the work of connecting the body tissue, cell, and organs. Steve Gschmeissner/Science Photo Library/Getty Images. Is a structureless material secreted by both the epithelial cells and the connective tissues that are by the epithelium. [15]:161 Elastic fibers, made from elastin and fibrillin, also provide resistance to stretch forces. Dense connective tissue can be categorized into dense regular, dense irregular, and elastic connective tissues. Collagen and elastin. There are three main groups of connective tissues: loose connective tissue, dense connective tissue, and specialized connective tissue. column shaped. Both the ground substance and proteins (fibers) create the matrix for connective tissue. There are many different kinds, and they mainly serve as structure and support, often connecting two other types of tissue to each other. Loose connective tissue is named so because of the "weave" and type of its constituent fibers. Adipose tissue forms an insulating layer under the skin, storing energy in the form of fat. It differs from the other three tissues in that the extracellular components (fibers and intercellular substances) are abundant. Simple squamous b. They include: Epithelial Tissue; Muscle Tissue; Connective Tissue; Nerve Tissue; Epithelial Tissue. The human body possesses four types of tissues, namely muscle, epithelial, connective and nervous. All connective tissue consists of three main components: fibers (elastic and collagenous fibers),[1] ground substance and cells. This clear fluid originates from blood plasma that exits blood vessels at capillary beds. This matrix can be liquid or rigid. Connective tissue can be broadly classified into connective tissue proper and special connective tissue. Adipose tissue is a form of loose connective tissue that stores fat. This image of the dermis of the skin shows dense fibrous connective tissue. [15]:171, Mesenchyme is a type of connective tissue found in developing organs of embryos that is capable of differentiation into all types of mature connective tissue. Part A. Extra cellular matrix. It forms part of the skeletal system in humans and in other vertebrates, and is also known as gristle. Blood, bone, cartilage, tendons, ligaments, adipose (fat), and lymph are all examples of connective tissue. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue. ThoughtCo, Aug. 27, 2020, thoughtco.com/connective-tissue-anatomy-373207. Composition of matrix c. Cell shape d. Both the number of layers and the cell shape 3. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue. For example, blood contains plasma as its matrix and bone's matrix is rigid. )[7] Loose and dense connective tissue are distinguished by the ratio of ground substance to fibrous tissue. Connective tissues are specialized tissues, which provide support and hold the body’s tissues together. The epithelial tissue that has the ability to stretch is a. You can find cartilage connective tissues in various parts of the body, specifically in the ear, joint surfaces, rings around the trachea, in between the ribs and sternum, growth areas of the bones, and intervertebral discs. Areolar connective tissue is one of six forms of connective tissue within the body and is named after the airy appearance of the tissue. As the name implies, connective tissue serves a connecting function: It supports and binds other tissues in the body. 1. All are immersed in the body water. New vascularised connective tissue that forms in the process of wound healing is termed granulation tissue. Adipose tissue also produces endocrine hormones that influence activities such as blood clotting, insulin sensitivity, and fat storage. ... One of the four primary tissues of the body. Loose connective tissue has much more ground substance and a relative lack of fibrous tissue, while the reverse is true of dense connective tissue. 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. [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. 1 layer of cells. These cells include fibroblasts, fat cells, mast cells, and also white blood cells like the macrophages, plasma cells, etc. Connective tissues are most abundant and widely distributed in the body of complex animals. They also allow organs to resist stretching and tearing forces. Allow organs like arteries and lungs to recoil, This page was last edited on 29 November 2020, at 12:26. They range from soft connective tissues to specialized types, which include cartilage, bone, adipose, and blood. The primary elements of connective tissue include a ground substance, fibers, and cells. This micrograph shows cancellous (spongy) bone from a vertebra. Retrieved from https://www.thoughtco.com/connective-tissue-anatomy-373207. columnar. What parts of the body are classified as connective tissue? Together the ground substance and fibers make up the extracellular matrix. Types of Connective Tissues There are seven types of connective tissues found in the body of people. Susumu Nishinaga/Science Photo Library/Getty Images. They have been classified based on the type of cell, function, and location in the body. All layers and organs in the body are lined by a group of tissues called epithelial tissues which are commonly referred to as epithelium. stratified epithelium . [16] Another type of relatively undifferentiated connective tissue is the mucous connective tissue known as Wharton's jelly, found inside the umbilical cord. Connective tissues perform many functions in the body, but most importantly, they support and connect other tissues; from the connective tissue sheath that surrounds muscle cells, to the tendons that attach muscles to bones, and to the skeleton that supports the positions of the body. Interestingly enough, blood is considered to be a type of connective tissue. Adipose tissue is a specialized connective tissue consisting of lipid-rich cells called adipocytes. The blood and lymph vessels are immersed in the connective tissue media of the body. Connective tissue has three main components: cells, fibers, and ground substance. more than 1 layer of cells.
