Connective tissue has a wide variety of functions that depend on the types of cells and the different classes of fibers involved. Loose and dense irregular connective tissue , formed mainly by fibroblasts and collagen fibers , have an important role in providing a medium for oxygen and nutrients to diffuse from capillaries to cells, and carbon ...
Dense connective tissue, also called dense fibrous tissue, is a type of connective tissue with fibers as its main matrix element. [1] The fibers are mainly composed of type I collagen. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers. Dense connective tissue forms strong, rope-like ...
Most cell types in loose connective tissue are transient wandering cells that migrate from local blood vessels in response to specific stimuli. Loose connective tissue, therefore, is a site of inflammatory and immune reactions. In areas of the body where foreign substances are continually present, large populations of immune cells are maintained.
66784. Anatomical terms of microanatomy. [ edit on Wikidata] A mast cell (also known as a mastocyte or a labrocyte [1]) is a resident cell of connective tissue that contains many granules rich in histamine and heparin. Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems.
Reticular connective tissue is a type of connective tissue with a network of reticular fibers, made of type III collagen (reticulum = net or network). Reticular fibers are not unique to reticular connective tissue, but only in this tissue type are they dominant. Reticular fibers are synthesized by special fibroblasts called reticular cells. The ...
Fibroblast. A fibroblast is a type of biological cell typically with a spindle shape [1] that synthesizes the extracellular matrix and collagen, [2] produces the structural framework ( stroma) for animal tissues, and plays a critical role in wound healing. [3] Fibroblasts are the most common cells of connective tissue in animals.
e. In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ.
Dense regular connective tissue ( DRCT) provides connection between different tissues in the human body. The collagen fibers in dense regular connective tissue are bundled in a parallel fashion. DRCT is divided into white fibrous connective tissue and yellow fibrous connective tissue, both of which occur in two forms: cord arrangement and ...
