It has a branched and mesh-like pattern, often called reticulum, due to the arrangement of reticular fibers (reticulin). It includes fibrous tissues, fat, cartilage, bone, bone marrow, and blood. Connective tissue is the most abundant and widely distributed of the primary tissues. It provides mechanical strength, physical and metabolic support to all or any the opposite kinds of tissues. This is considered a specialized form of connective tissue. It has homogenous, transparent, semi-fluid and gelatinous matrix. Based on its location, fat tissue is divided into parietal (under the 1I. These fibers are a significant part of most of the fibrous connective tissues, and are always seen to be the dominant ones. Image Source: austincc.edu. These reticular fibers are secreted by reticular cells, which surround the fibers. Watch Queue Queue. There are more than 20 types of reticular fibers. Find high-quality stock photos that you won't find anywhere else. These collagen fibers are slightly wavy and can stretch a little bit. Areolar Connective Tissue - Collagen, elastic and reticular fibers with interspersed fibroblasts, macrophages, plasma cells, adipocytes, and mast cells with a semifluid ground substance. You will never see reticular connective tissue alone--there will always be other cells scattered among the reticular cells and reticular fibers. Mesenchyme. Reticular connective tissue forms a scaffolding for other cells in several organs, such as lymph nodes and bone marrow. Loose connective tissue It contains reticular fibers and reticular cells. Structural elements of connective tissue: Connective tissues consist of three parts: cells suspended in a ground substance or matrix; and most have fibers running through it. The human body is composed of just four basic kinds of tissue: nervous, muscular, epithelial, and connective tissue. Reticular connective tissue: cells and structure ... Types Of Connective Tissue - What Is Connective Tissue - Functions Of Connective Tissue - Duration: 6:49. In bone, its lacunar regions (spaces between overlapping tropocollagen units) may act as nucleation sites for the hydroxyapatite crystals of bone matrix. *Location:-Beneath Skin-Around Kidneys-Behind Eyeballs-Surface of Heart *Function:-Protects-Insulates-Stores Fat. Location? Areolar connective tissue: These are simplest and most widely distributed connective tissues. Biology 235 Human Anatomy and Physiology. Fibroblasts and "branches" Supported by a branching framework of collagen fibers (reticular fibers) Fibers are heavily concentrated Under a microscope, looks like a lattice of fibers Other types of cells are found in and along the framework tissues Composed In bone, its lacunar regions (spaces between overlapping tropocollagen units) may act as nucleation sites for the hydroxyapatite crystals of bone matrix. Loose connective tissue proper includes adipose tissue, areolar tissue, and reticular tissue. The fibers provide support and stability to other types of cells. Histology - Reticular connective tissue View Related Images. The area in the box has been enlarged in the next image. Areolar Connective Tissue:is a loosely arranged connective tissue that is widely distributed in the body such as in gastrointestinal tract, blood vessels and ducts of glands. Cartilage 3. Reticular fiber is also formed from the same protein subunits as collagen fibers; however, these fibers remain narrow and are arrayed in a branching network. Elastic fibers are long, thin fibers that form branching network in the extracellular matrix. Reticular fibre, in anatomy, fine fibrous connective tissue occurring in networks to make up the supporting tissue of many organs. FUNCTIONS OF CONNECTIVE TISSUES 1.Binds body tissues together 2.Supports the body 3.Provides protection 4.Insulates to maintain body temperature 5.Transportation of other molecules. Adipose tissue is found in specific locations, referred to as adipose depots. Reticular fibers are also found beneath the basal lamina of epithelium and in other types of connective tissue. This tissue resembles areolar connective tissue, but the only fibers in its matrix are the reticular fibers, which form a delicate network. It holds organs in place and attaches epithelial tissue to other underlying tissues. This tissue type forms a structural framework (fibrous cartilage) for organ cells in m… It provides strong support while providing pads for shock absorption. The areolar tissue contains collagen fibers, reticular fibers and a few elastic fibers embedded in a thin and almost fluid-like ground substance.

In specialized connective tissue, different fixed cells like osteocytes (bone) and chondrocytes (cartilage) are found in large quantities. Connective tissue proper: dense regular connective tissue: function . embedded in abundant ground substance. This tissue forms the fascia, which is a fibrous membrane that wraps around the muscles, blood vessels, and nerves. Connective tissues can have various levels of vascularity. As the name implies, connective tissues often bind other organs together, hold organs in place, cushion them, and fill space. Reticular cells produce the reticular fibers that form the network onto which other cells attach. Reticular connective tissue is found around the kidney, liver, the spleen, and lymph nodes, Peyer's patches as well as in bone marrow. Location Collagen fibers are found in all connective tissues and in the reticular laminae of certain basement membranes. Reticular Connective Tissue This tissue resembles areolar connective tissue, but the only fibers in its matrix are the reticular fibers, which form a delicate network. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column. It also helps to bind together the cells of smooth muscles. Connective tissue is found between other tissue types and organs. Connective tissue is the most abundant, widely distributed, and varied type. Reticular fibers are not unique to reticular connective tissue, but only in this type are they dominant. The functions of areolar connective tissue include the support and binding of other tissues. Reticular cells produce reticular fibers but play the role of fibrocytes in areas of tissue that contain reticular fibers. Cartilage. As it comprises about 20-25% of total body weight in healthy individuals, the main function of adipose tissue is to store energy in the form of lipids (fat).
