The eye muscles insert on this coat. Sclera: The sclera is dense, irregularly arranged connective tissue, forming the white outer coat of the eye. Dense regular connective tissue is an extremely strong tissue type that can resist a great deal of force along the length of their fibers while still remaining extremely flexible. A. Hyaline Elastic Fibroelastic Bone Cancellous (spongy: lg. Dense Regular Dense Irregular Loose One way that connective tissue varies in mechanical strength is by the density and organization of its collagen fibers. Pseudostratified Columnar Epithelium Buy this book on publisher's site. more info. Dense Irregular Connective Tissue. Dense irregular connective tissue contains collagen and elastic fibers which are found running in all different directions and planes. The Conjunctiva of the eyeball is located on the outside of the sclera and it is continuous with the moist epithelium of the Corneal connective tissue, … The fibres may be regularly or irregularly arranged ; types: White fibrous tissue ( tendon and sheath) Yellow elastic tissue (Ligament; source;cnx.org. Electron micrograph of a small area of dense fibrous connective tissue, illustrating the intimate association of cells and fibres. The area beneath the stratified squamous epithelium shown in slide 33 is the dermis, which is composed of dense irregular connective tissue. Fiber types: Primarily collagen fibers, some elastic fibers (typically around blood vessels, nerves and especially around glands. Elastic connective tissue is a modified dense connective tissue that contains numerous elastic fibers in addition to collagen fibers, which allows the tissue to return to its original length after stretching Figure 4.10). The dense connective tissue is divided into dense regular connective tissue and dense irregular connective tissue based on fibers arrangement. When the collagen fibers are randomly oriented —as in the dermis of the skin—the tissue is called dense irregular connective tissue. It is usually located in the capsules and walls of the organs, the dermis of the skin and glands. The cornea is your eye’s clear, protective outer layer.

Publisher Name Springer, Berlin, Heidelberg. The Cornea is the transparent ´window´ for the incoming light at the visible anterior side of the eyeball, whereas the rest of its wall is built by the opaque Sclera. These images compare dense irregular connective tissue stained by the Verhoeff method (left) and the Movat pentachrome stain (right); in both stains, elastic fibers appear black. The region where it has mostly fibers and fibroblasts is dense irregular connective tissue. Dense Irregular Connective Tissue. Ref code # 5. Muscle tissue: mesoderm 4. Corneal stroma is ectoderm-derived. Tendon contains a high ratio of collagen to number of cells and the collagen fibers are arranged in parallel arrays along the lines of tension. The connective tissue is the glue that holds all other tissues together, it has the important function of ensuring that our body systems work in harmony. The region is referred to as the angle of the eye because in cross section a triangular space is formed between the cornea, sclera and ciliary body. Blood Tissue. Coarse, thick, intertwined bundles of collagen fibers arranged irregularly Fibroblasts are sparse (produce collagen) What are the two types of dense irregular connective tissue? There are many different types of connective tissue, with loose and dense connective tissue … Metabolic. When a connective tissue has a high concentration of cells or fibers, it has a proportionally-less-dense matrix. Supports, insulates, and protects the body. T he main role of dense regular connective tissue is withstand strong mechanical stress. The fiber orientation differs from layer to … B. Dense irregular connective tissue is found in high concentrations in body parts where support is needed to prevent the effects of forces that pull in multiple directions. Slide 250-2 (vagina, trichrome) View Virtual Slide. Examples of fixed cells. Dense irregular connective tissue has an irregular, somewhat disorderly, dense weave of thick collagen type I fibers, with bundles of fibers oriented in all directions. Limbus: The limbus is the transitional zone between the cornea and sclera. Loose connective tissue. Obtain a slide of skin and prepare to examine the dermis with the scanning objective lens. This arrangement gives the tissue greater strength in all directions and less strength in one particular direction.

You will find the collagen fibers arranged in a definite plan in the histology of dense regular connective tissue. b. Hereditary disorders of connective tissue are a heterogeneous group of generalized single-gene-determined disorders that affect one or another of the primary elements of the connective tissues (collagen, elastin, or ground substance [glycosaminoglycans]). Tendons connecting muscles to bone and ligaments connecting bone to bone are examples of dense connective tissue proper. Can you distinguish between active and inactive fibroblasts?
