All connective tissues are mostly composed of ___ nonliving material _____ material, called the e.g. Bone is a specialized connective tissue type. Loose and Dense Connective Tissues. Three types of loose connective tissue are recognized. )These tissues vary in size, structure, and density, determining the function they will perform in the body. It can also be found in mucous membranes, around blood vessels, and around the organs. Connective Tissue: Connective tissue consits of cells, fibers, and a gelatinous mixture called ground substance. DNA … It has dispersed cells, more extracellular material and extensive protein fibers in the extracellular matrix. Areolar tissues are one of the six types of connective tissues in the body. The cells in the connective tissue rest on a basement membrane. Dense connective tissue is reinforced by bundles of fibers that provide tensile strength, elasticity, and protection. Loose connective tissue is named so because of the "weave" and type of its constituent fibers. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. High levels of collagen fibers make our bones shock-resistant by absorbing … Gound substance 2. relative proportion and variety of fibers in the ground substance 3. number and variety of cells in the ground substance. These cells are typically found in close proximity to loose connective tissue. ( Log Out /  All connective tissues have three factors in common that set them apart from other tissue types: They all have a common origin: they all develop from ____ mesenchyme _____, a loose and fluid type of embryonic tissue. e.g. Connective tissue cells are divided into fixed and wandering types. Mucoid Tissue: this type of loose connective tissue also occurs in an embryo particularly prominent in the umbilical cord, where it is called Wharton’s jelly.

Loose connective tissue is the most widely distributed type of connective tissue, found in the lining of the body's inner surfaces Examples of loose connective tissue include; the lamina propria of the alimentary and respiratory tracts, mucous membranes of reproductive and urinary tracts, glands, mesentery and dermis of the skin. Like all tissue types, it consists of cells surrounded by a compartment of fluid called the extracellular matrix (ECM). However connective tissue differs from other types in that its cells are loosely, rather than tightly, packed within the ECM. Instead of an aqueous extracellular matrix, the ground substance is mineralized and hard. Moreover, it fills spaces between organs and protects organs. Connective tissue is diversified in function and may be divided into four categories according to the type of matrix. Dense regular collagenous connective tissue There are three main categories of connective tissue. From fat to tendons, connective tissue proper is the most diverse group in this tissue family. It can also be seen under the skin, connecting to the muscles beneath. Required fields are marked *. Types of Connective Tissues. Dense connective tissue is reinforced by bundles of fibers that provide tensile strength, elasticity, and protection. Dense connective tissue. Dense connective tissues (DCT) are made up of large fibers that give these structures considerable strength. These are: Areolar Connective Tissue; Adipose Tissue; Dense Irregular Tissue; Dense Regular Tissue; Cartilages; Bones; Blood; 1. This type of tissue is found around the kidney, spleen, lymph nodes, and inside bone marrow. Varying the types and quantities of each of these components results in the formation of the different types of connective tissue proper. Objectives •Describe each type of connective tissue (CT) and explain where they are found. Pregnant women tend to develop additional deposits of adipose tissue. Loose connective tissues. These fibers form an irregular network with spaces between the fibers. Resident cells are present in tissues continuously and typically exhibit little movement. In cartilage cartilage, flexible semiopaque connective tissue without blood vessels or nerve cells. –lamina densa of the basal lamina Type V. –in the placenta Type VII. dense regular connective tissue which is found in tendons and ligaments, and is shown below. Connective tissue is the tissue that connects, separates and supports all other types of tissues in the body. Its job is to provide support, strength, and elasticity. It lies under the skin and in between organs. Connective tissue proper is populated by a variety of cell types that differ in their morphology and function, mobility and origin. Resident cells > Connective tissue cells are classified as either resident or migratory. Connective tissue is one of the four types of tissues that provides support to other organs and connects them together. These tissues are found wherever strength is especially important. Fat, or adipose tissue, is also considered one of the types of connective tissue. –in hyaline cartilage Type III. Figure 1. Image by AnatomyBox; Notice the abundance of space between the cells and fibers. wandering cells. It lies under the skin and in between organs. e.g. CONNECTIVE TISSUE PROPER (examples of these are shown below) loose irregular connective tissue ; dense irregular connective tissue; SPECIALISED CONNECTIVE TISSUES. Skeletal Muscle – Parts and Classification, Types of muscles – Skeletal, Cardiac and Smooth, Cardiovascular System – Structural Components, Components of Vascular System and Types of Circulation, End Arteries, Anastomosis and Collateral Circulation, Nervous System – Functions and Subdivisions, Autonomic Nervous System – Sympathetic and Parasympathetic, Anterior Triangle of Neck – Submental and Muscular triangles, Arm – Anterior and Posterior Compartments, Forearm- Flexor and Extensor Compartments, Conducting System and Nerve Supply of Heart, Anatomosis – Trochanteric, Cruciate , Around Knee, Coeliac trunk, Superior and Inferior Mesenteric Arteries, Pelvic viscera and Perineum-Important Questions, Development of pharyngeal Arches, Pouches, Development of Urinary Bladder and Urethra, Development of Urinary & Reproductive Systems- Exam Questions, Development of Gastrointestinal Tract and Diaphragm- Important Questions, Development of Face, Palate ,Tongue, Pharyngeal arches and Thyroid- Important Questions, Development of Cardio-vascular System-Important Questions. Classifications of Loose Connective Tissue. It is also critical for proper immune function. This is what makes areolar tissue a loose connective tissue. Tissues types, Epithelial tissue features, Covering & Glandular Epithelium . Considering its structure and the wide variety of functions, the connective tissue is the most known diverse tissue out of all basic tissues. Loose and dense connective tissue are distinguished by the ratio of ground substance to fibrous tissue. Reticular connective tissue is a network of reticular cells made up of collagen. It is the cells that store triglycerides (fats), and lies directly underneath your skin, providing insulation. Reticular fibers protect lymph organs, hold together adipose tissue, and form the soft skeleton. Connective tissue proper: loose connective tissue, reticular: location lymphoid organs (lymph nodes, bone marrow, and SPLEEN) Connective tissue proper: dense regular connective tissue: description Connective tissue proper consists of loose connective tissue and dense connective tissue (which is further subdivided into dense regular and dense irregular connective tissues.) Types of Connective Tissues. Transports fluids and dissolved materials. 400x. –attaching the basal lamina to the lamina reticularis. It also performs a protective function, surrounding some of your organs such as your kidneys, and providing padding to some delicate joints. Collagen tissues are also referred to as white connective tissues and elastic tissues are referred to as yellow connective tissues. Both tissues have a variety of cell types and protein fibers suspended in a viscous ground substance. It is composed of a thin jelly-like ground substance in which are scattered a few cells. Types of Supportive and Fluid Connective Tissue, Connective Tissue by Encyclopedia Britannica, Classification of Connective Tissue by the University of Leeds, Dense Irregular Connective Tissue by Histology Olm, Types of Animal Tissue by Ivy Rose Holistic. It consists of collagen, elastic, and reticular fibers, and it binds your skin to the underlying muscles. Another of the types of connective tissue is blood. However, you probably don’t realize just how much of your body is made up of connective tissue, what it actually does in your body, and how important of a structure it really is. It is found in the dermal layer of the skin, and walls of tubular organs, and in glandular tissue and organ capsules. Change ). Dense connective tissue. Fibrocytes do not contain as many organelles as most cells; however, this is when the cell is dormant. It has a high tensile strength which allows it to passively transmit mechanical forces into all sorts of directions without tearing.
