Areolar Tissue
Areolar tissue is the most common connective tissue in the body. It is a network of loosely organized collagen, elastic and recticular fibers that are maintained by fibrocytes. This mesh allows blood vessels, nerve and interstitial fluids to penetrate. Immune … Continue reading Areolar Tissue
Dense Regular Connective Tissue
Dense regular connective tissue composed of collagen fibers arranging in a parallel fashion and are themselves produced and maintained by fibrocytes. Because of the arrangement, dense regular CT can resist pulling in the direction parallel to the fibers (tensile strength) … Continue reading Dense Regular Connective Tissue
Thymus
Thymus is an important lymphoid organ especially in the neonatal and pre-adolescent periods. Its function is to mature the T-lymphocytes that are part of the adaptive immune response. Thymus aplasia can lead to profound immunodeficiency and is one of the … Continue reading Thymus
Trachea
Pictures are of unknown organism but possible from small mammals. The relationship between the trachea and esophagus can be seen in the third one. The “C” shape cartilage ring that form most of the trachea and the trachealis muscle at … Continue reading Trachea
Reticular Fibers
Reticular fibers is a type of connective tissue normally found in lymphatic organs. It is composed of Type III collagen that form a network that act as a mesh for cells. Pictures were taken from slides of unknown organism and … Continue reading Reticular Fibers
Pia Mater
Pia mater is the innermost layer of the meninges, clinging tightly to the brain with all the sulcus and fissure. It is composed of a thin layer of simple squamous epithelial cell and areolar tissue. It is further invested with … Continue reading Pia Mater
