Areolar connective tissue

Edema An imbalance between the production and removal of tissue fluid can lead to an accumulation of fluid within the affected tissues.

Interactive Link Questions Visit this link to test your connective tissue knowledge with this question quiz. There are two basic types of adipocytes: Each adipocyte is surrounded by a basement membrane. Many such proteoglycan subunits then attach themselves to a molecule of hyaluronic acid, which is the principal unsulfated glycosaminoglycan found in ground substance.

In connective tissue, elastic fibers are produced by fibroblasts. Blood and Haemopoietic Tissue: Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength.

Reticular tissue is a mesh-like, supportive framework for soft organs such as lymphatic tissue, the spleen, and the liver [link]. The ground substance either may be clear and homogeneous or may contain fibrous tissue.

Histology Photomicrographs

She consoles you by mentioning that well known tennis players such as Venus and Serena Williams and Rafael Nadal have also suffered from tendinitis related injuries. These cells remain supported by a loose framework of areolar tissue.

Loose connective tissue

It differs from the white fibrous tissue in the following respects: Adipose tissue is absent in eyelids, penis, scrotum, labia minora, cavity of cranium, lungs except their roots etc. In the case of capillaries, which are common in loose connective tissue, the endothelial cells that encircle Areolar connective tissue lumen are joined at their lateral borders by tight junctions, usually fascia occludens.

This is a section through the duodenum slide. Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins.

Dense connective tissue proper is richer in fibers and may be regular, with fibers oriented in parallel as in ligaments and tendons, or irregular, with fibers oriented in several directions. A second method, involving lymphocyte reactivity in a mixed lymphocyte culture, for determining HLA-D or lymphocyte-defined antigens, is now only rarely used.

The high caloric content of triglycerides provides an efficient store of fuel for cellular metabolism. It is made up of bone cells and intercellular ground substance. Lymph contains a liquid matrix and white blood cells. Elastic cartilage maintains and strengthens the attached organs.

This means that tissue fluid is produced at the arterial end of the capillary and resorbed at its venous end. In firmness and elasticity it occupies a position intermediate between fibrous tissue and bone.

The fibroblasts are irregularly scattered. It occupies the interspaces of the body. Tendinitis is the inflammation of a tendon, the thick band of fibrous connective tissue that attaches a muscle to a bone. Tissue fluid When blood passes through a capillary, the hydrostatic pressure at the arterial end is greater than at the venous end.

Other functions are to provide strength, elasticity, support to the parts where this tissue is present. The three parts of basement membranes —The lamina densa The middle part, called the lamina densa, was formerly called the basal lamina. It is so named because its fibers are far enough apart to leave ample open space for interstitial fluid in between areola is Latin for a "little open space".

Remember, the ground substance appears unstained because it is lost during tissue preparation. Such stellate cells are typically found in the transverse section of tendons. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone.

It is comparatively rare in the adult.As stated earlier, the areolar tissue is the most widely distributed connective tissue in the body. It is present under the skin as subcutaneous tissue in between and around muscles, nerves and blood vessels in sub-mucosa of gastrointestinal tract and respiratory tract, in the bone marrow, between the lobes and lobules of compound glands and in.

Loose connective tissue (areolar) is located under the thick eosinophilic basement membrane of the respiratory epithelium in the trachea. A major component of loose connective tissue is amorphous ground substance which does not stain with routine H & E.

The most. Loose connective (areolar) tissue. Origin: mesenchyme. Location: filling between apposed body parts, beneath the epithelia, external wrapping for vessels, nerves, muscles and fasciae. ground substance. Function: permission of diffusion of oxygen and nutrients between the microvasculature and adjacent tissue.

Location: between. Areolar tissue IS fibrous connective tissue, but there are also other kinds—reticular, dense irregular, and dense regular fibrous connective tissues.

Areolar tissue differs from the first of those in having no network of reticular fibers; from the. Look for adipose tissue in Slide #30 which is taken from abdominal mesentery (the connective tissue that suspends the viscera within the abdominal cavity).

Some of the individual fat cells are often broken during tissue preparation, but the overall impression of what the tissue looks like is the important point. Areolar tissue is a common type of connective tissue, also referred to as “loose connective tissue”. It is strong enough to bind different tissue types together, yet soft enough to provide flexibility and cushioning.

It exhibits interlacing, loosely organized fibers, abundant blood vessels, and significant empty space.
