Connective tissue is classified into two subtypes which are soft and specialized connective tissue. Reticular connective tissues has a loose network of fine fibers. The tissue is similar to connective tissue with a high amount of elastic fibers, except that in reticular connective tissue, the collagen fibers are branched, while elastic fibers lie parallel to each other. These tissues have a peculiar feature; they never exist alone. Functions: The reticular connective tissue is especially adapted to provide strength and support as it forms the supporting framework (stroma) of many organs. Areolar Connective Tissue 40X. Areolar connective tissue consists of fibers (collagen, elastic and reticular) and several types of cells (Fibroblasts, macrophages, adipocytes, mast cell, plasma cell and other kinds of blood cells). ... Areolar and reticular tissue are types of loose connective tissue that provide support, as well as fill up unused spaces in the body. Cells are supported by an extracellular matrix, in a tissue. These tissues, together with blood and lymph, form the system of tissues within the body. Hepatocytes in the liver. Each thymic lobule is clearly divided into an outer cortex region and an inner medulla. The key difference between papillary and reticular layer is that papillary layer is the thin superficial layer of the dermis composed of loose connective tissue while the reticular layer is the deeper thick layer of the dermis composed of dense connective tissue.. Sep 6, 2014 - Reticular connective tissues are the backbone of the human body tissue structure. Reticular tissue and adipose tissue are two types of connective tissue having special properties. Loose network of reticular fibres and fibroblasts; the space between the fibres is filled with lymphocytes and other blood cells. Types of Connective Tissues. Another type of connective tissue is rich in pigment cells (for example, in the choroid of the eye). This is a loose connective tissue made up of all components found in connective tissue proper.

The cortex is composed of dense aggregates (no follicles) of small lymphocytes (thymocytes) which are surrounded by reticular connective tissue. •Relate the functions of each connective tissue to their structural organization. Connective tissue develops from an embryonic type of tissue that is made up of undifferentiated cells known as mesoderm, and its main purpose is to give and maintain the structure … The most highly organized lymphoid tissues are in the thymus and lymph nodes, which are well-defined encapsulated organs with easily identifiable architectures. The other three are nervous, muscle and epithelial tissue. Dense Regular Connective Tissue. Compare the general structure of the various types of tissue. Loose connective tissue (areolar, adipose and reticular) Dense connective tissue (regular, irregular, elastic) Three types of loose connective tissue. Reticular cells, these are the fibroblasts of reticular connective tissue, that synthesize the reticular fibers. Description: This is a section of reticular tissue from within a lymph node. But if you obtain that the lack of pattern is one of the distinctive characteristics of areolar connective tissue, you have got a cue that will allow you … Reticular connective tissues are arranged along with different cells in various organs like bone marrow, lymph nodes, spleen, liver, kidneys, and even under the skin. Areolar connective tissue 40X Areolar connective tissue has no obvious structure, like layers or rows of cells. These are: Areolar Connective Tissue; Adipose Tissue; Dense Irregular Tissue Brief Introduction to Connective tissue Connective tissues are found throughout the whole body, in fact they make up much of the body.Connective tissue "are the most abundant type of tissue by weight." Connective Tissue Definition. Site & function: reticular tissue is limited to certain sites, it forms the supporting stroma for: Hemopoietic tissue in the bone marrow. Connective tissue (CT) is a one of the four main classes of tissues. Location. Unit 2: Cells & Histology Chapter 4.2 Connective Tissues Connective Tissue Function: - Loose connective tissue works to hold organs in place and is made up of extracellular matrix and collagenous, elastic and reticular fibers. Scattered among the spaces within the fibers are numerous reticular cells (lymphocytes). Adipose connective tissue Muscle structure. You might think that this would make it harder to identify. Of the four tissue types we have in our bodies, connective tissue is the most abundant. The feline thymus is an elongated multilobed structure located in the thoracic mediastinum. Areolar connective tissue is soft and gel like with some elasticity and holds interstitial fluid which carries and delivers nutrients or waste. -water and salts provide structure from semi-fluid adipose to hard bone. The underlying connective tissue attaches to the basal lamina with collagen VII anchoring fibrils and fibrillin microfibrils.. Connective tissue consists of specialized cells that are embedded in the extracellular matrix . Specialized Connective Tissue. Dense connective tissue is dense because of the high proportion of fibers that run parallel to each other. (Micrograph provided courtesy of Jennifer MacDonald, Mt. Structure. Lymphoid tissue in lymph nodes and spleen. It consists of cells, fibers & ground substances. Fibers are densely packed and organized in parallel to create a strong tissue capable of withstanding the pull of muscle and … 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. Meanwhile, reticular fibers are highly branched fibers which form a delicate network in organs that have lots of mesh-like internal structure. Connective tissue can bind & … Disorders of connective tissue are discussed in detail in the connective tissue diseases article. Connective tissue holds our tissues and organs together. Category of CTP ... Reticular Connective Tissue. In addition, they perform the work of connecting the body tissue, cell, and organs. San Antonio College). 1. Connective Tissue Chapter 4.2 Human Anatomy & Physiology Connective Tissue Function: - Binds structures together - Provides support & protection - Fills spaces - Produces blood cells - Stores fat For energy, insulation, organ protection Structure: - Tissue cells are widely separated by extracellular matrix - Can be solid, semisolid, or liquid Matrix of connective tissue … Structure. It … Dense regular connective tissue makes up tendons and ligaments. In the spleen (a soft, purplish organ lying high in the abdomen), the lymphoid tissue … As may be obvious from its name, one of the major functions of connective tissue is to connect tissues and organs. The structure of the collagen lattice provides more strength and support to the underlying tissue and is less springy than elastic tissue. There are seven types of connective tissues found in the body of people. Function. Loose Connective Tissue. Dense fibrous connective tissue: Has a high concentration of fibers, interwoven with each other, and closely packed in to parallel bundles. the ground substance & fibers make up the extracellular matrix. The cells that make the reticular fibers are fibroblasts called reticular cells. Areolar connective tissue has no apparent structure, like layers or rows of cells. You might think that this would make it tougher to identify. Loose -mesh of reticular fibers-Forms stroma of lymphatic organs -stroma of spleen, liver, lymph nodes, bone marrow. Connective tissue is the most widely distributed of the primary tissues. Reticular connective tissue is present in the liver, spleen, lymph nodes, thy­mus, tonsils, bone marrow and lamina propria of the gut wall. Forms a supporting structural framework; white blood cells remove old red blood cells in spleen and microbes in lymph nodes. Lymphoid tissue has several different structural organizations related to its particular function in the immune response. example: tendons and ligaments. Reticular tissue is a mesh-like, supportive framework for soft organs such as lymphatic tissue, the spleen, and the liver (Figure \(\PageIndex{4}\)). Dense connective tissue can be further classified into dense regular connective tissue and dense irregular connective tissue. As seen with the electron microscope, the basement membrane is composed of two layers, the basal lamina and the reticular lamina. Reticular connective tissue 40X Reticular connective tissue is named for the reticular fibers which are the main structural part of the tissue. •List the types of cells, fibers, and other extracellular matrix components found in connective tissues.
