Specialized connective tissue encompasses a number of different tissues with specialized cells and unique ground substances.

. For example it forms telae such as the tela submucosa and tela subserosa which connect mucous and serous membranes to the muscular layer. Reticular tissue is composed of a loose ground substance with distinctive reticular fibers. Connective tissue cell migration into the wounds starts by day three post-wounding. Loose connective tissue is a loose irregularly arranged connective tissue that consists of collagenous and elastic fibers a protein polysaccharide ground substance and connective tissue cells.

Loose connective tissue dense connective tissue and specialized connective tissue. Loose connective tissues are present all over the body where support and elasticity both are needed. They form the subcutaneous layer under the skin along with adipose tissues attaching muscles and other structures to the skin. The fibers are spread far apart and excessive numbers of cells are present.

These cells overlay loose connective tissue that contains variable elements of fat collagen and blood vessels. In this image of loose connective tissue of the GI tract submucosa you can see that the collagen fibers are very loosely and irregularly arranged. Loose connective tissue is the most abundant form of collagenous connective tissue. It allows water salts and various nutrients to diffuse through to adjacent or imbedded cells and tissues.

Blood vessels nerves and muscles all have a loose connective tissue wrapping. Ad Over 27000 video lessons and other resources youre guaranteed to find what you need. The areolar tissue fills the gap between the muscle fibers by surrounding them through blood and lymph vessels and provides strength to the abdominal cavity. Some are solid and strong while others are.

Collagen Fibers are found in most supporting tissues and collagen is the most abundant protein in the body Wheaters. Loose connective tissue also called Areolar is often used to link epithelia to other parts of the organ wall. Loose connective tissue works to hold. The loose connective tissue is made from the fat cells having less extracellular matrix.

Connective tissue as the name implies is a term given to several different tissues of the body that serve to connect support and help bind other tissues in the body. It is a category of connective tissue which includes areolar tissue reticular tissue and adipose tissue. It holds organs in place and attaches epithelial tissue to other underlying tissues. Reticular tissue a type of loose connective tissue in which reticular fibers are the most prominent fibrous component forms the supporting framework of the lymphoid organs lymph nodes spleen tonsils bone marrow and liver.

Reticular fibers type III collagen are too thin to stain in ordinary histological preparations but they are readily. Connective tissue can further be broken down into three categories. Loose connective tissue sometimes called areolar tissue is a cellular connective tissue with thin and relatively sparse collagen fibers. Much of the associated connective tissue is very loose because of edema a complication here because of a skull fracture.

Dense connective tissue helps attach muscles to bones and link bones together at joints. It contains all three types of fibers collagen elastic and reticular which are distributed randomly and crisscross in all directions as shown in Figure 1. Dense connective tissue is enriched in collagen fibers with little ground substance. Reticular tissue is associated with lymphoid tissue like lymph nodes.

Loose Connective Tissue Location Lamina propria areolar tissue Blood vessels Areolar tissue Found in the ducts of glands Areolar tissue Bone marrow Reticular tissue Spleen Reticular tissue Lymph nodes Reticular tissue Umbilical cord Mucoid tissue Embryo Mesenchyme embryonic tissue. The reticular fibers provide a loose flexible scaffold on which the cells rest. By light microscopy. Fibroblasts are the cells that produce collagen and elastin that form the fibers found in connective tissue.

Loose areolar connective tissue is the most abundant form of collagenous connective tissue. Look in the zone of loose connective tissue in the part of the section just beneath the epithelial layer. If the closely packed bundles of fibers are located in one direction it is. It has a viscous to gel-like consistency and plays an important role in the diffusion of oxygen and nutrients from the capillaries that course through this connective tissue as well as in th.

Areolar tissue wraps around muscles fills the spaces between muscle fascicles and surrounds blood. They usually stain pink and are the thickest fiber. 3 rows Loose connective tissue LCT also called areolar tissue belongs to the category of. Loose connective tissue is the most common type of connective tissue in vertebrates.

They are small purple cells found inside the. This is a section through the duodenum slide. Fats are stored in these tissues to provide energy and insulation. The reticular fibers stain black and blood cells lymphocytes are the predominant cell type.

It occurs in small elongated bundles separated by regions that contain ground substance. Loose connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. Its ground substanceoccupies more volume than the fibers do. Loose connective tissue is found between many organs where it acts both to absorb shock and bind tissues together.
