Dense connective tissue type

A healthy body can improve the quality of life. Therefore, many patients with dense connective tissue diseases want to fully understand the types of this disease and its experiments in order to prevent the disease from affecting their health and normal life. In order for you to have a comprehensive understanding, let's take a look at the detailed introduction below.

Dense connective tissue is a type of intrinsic connective tissue with fibers as its main components. The fibers are thick and densely arranged, and its main functions are support and connection. According to the properties and arrangement of fibers, they can be divided into the following types.

1. Regular dense connective tissue mainly constitutes tendons and aponeurosis. A large number of dense collagen fibers are arranged in parallel bundles along the direction of force, with very few matrix and cells located between the fibers. The main cellular components are tendon cells, which are a type of fibroblast with a special morphology. The cell body extends multiple thin wing-like processes and inserts between the fiber bundles. The nucleus is flat and oval and dark in color.

2. Irregular dense connective tissue is found in the dermis, dura mater, sclera and the membranes of many organs. It is characterized by thick collagen fibers of different directions interwoven into a dense lamellar structure, with a small amount of matrix and fibroblasts between the fibers.

3. Elastic tissue Elastic tissue is a dense connective tissue mainly composed of elastic fibers. The thick elastic fibers are either arranged in parallel bundles, such as the nuchal ligament and the yellow ligament, to accommodate spinal movement; or woven into membranes, such as the elastic tunica media of arteries, to buffer blood flow pressure.

There are also some parts of the body with connective tissue and dense fibers, and a large number and variety of cells, which are often called dense connective tissue, such as the connective tissue of the digestive tract and respiratory tract mucosa.

Dense connective tissue - Demonstration: Section 23

Take the tendon of the animal, cut it longitudinally, and stain it with hematoxylin-eosin.

Tendons are regular, dense connective tissues. Under a microscope, tendons are composed of many parallel and closely arranged collagen fiber bundles (stained bright red) and tendon cells (stained blue). Note that the tenocytes are arranged in single files between the fiber bundles. The cross section is long and fusiform, with an oval or liver-shaped nucleus. The nuclei of two adjacent cells are often very close.

Dense connective tissue types and experiments. For patients with this disease, they must go through the above introduction to fully understand the types of this disease and its experiments. After a comprehensive understanding, choose a large hospital and carry out effective treatment through meticulous treatment. I believe that through treatment, they will be able to recover as soon as possible.
