Because the endometrium is an epithelial tissue. Collagen and elastic fibers are produced by Fibroblasts which are found in connective tissue not epitheliam. Does that answer your question? Or do you want a more indepth response?
Areolar tissue contains a gel-like ground substance, collagen fibers, elastic fibers, and various cells such as fibroblasts, macrophages, and mast cells. It provides support and flexibility to surrounding structures in the body.
Osteoblasts are young bone cells that help to build and repair bones by secreting collagen fibers and other components of the bone matrix.
Fibers typical of a connective tissue matrix, such as collagen and elastic fibers, are not normally found in blood. Blood primarily consists of plasma, red blood cells, white blood cells, and platelets. Fibers typically found in connective tissue are found in tissues like tendons, ligaments, and the extracellular matrix of organs.
Chondrocytes are cartilage cells, and collagen fibers are typically associated with providing structural support and strength to connective tissues, such as cartilage. Chondrocytes help maintain the extracellular matrix of cartilage, while collagen fibers form a network that gives cartilage its resilience and ability to withstand mechanical stress.
Loose Areolar CT: gel-like matrix with fibroblasts, macrophages, mast cells and collagen and elastic fibers, beneath epithelium, covering ventral organs, wraps & cushions organs.Adipose Tissue: closely packed adipocytes (fat-cells) Location = under skin (as subcutaneous layer), around kidneys and eyeballs, breasts, Functions = energy store, insulation, protection.Reticular CT: network of reticular fibers within loose ground substance and reticulocytes, Function = support.Dense Regular CT (White Fibrous CT), primarily collagen Location = tendons, ligaments, Poor blood supply = slow to no healing.Dense Irregular CT: primarily collagen fibers randomly arranged, Function = provides tensile strength.Elastic CT: primarily elastin fibers, Function = durability with stretch.Plus bone and blood are also considered as tissues.
The three types of protein fibers in connective tissue are collagen, elastic, and reticular fibers. Collagen fibers provide strength and support, elastic fibers allow for stretch and recoil, and reticular fibers form a network to support other cells and structures.
The dermis contains mainly collagen fibers, which provide strength and support to the skin. Additionally, there are elastic fibers that allow the skin to stretch and recoil. Finally, reticular fibers can also be found in the dermis, providing a supportive framework for the skin cells.
The dermis contains dense irregular connective tissue with elastic fibers and collagen type I. It also contains very few fibroblast cells.
Fibroblasts are cells within a body that make collagen, glycoproteins, reticular and elastic fibers. They are mainly found in connective tissues.
Osteocytes are bone cells responsible for maintaining bone tissue, but they do not directly produce collagen fibers. Collagen fibers are mainly secreted by osteoblasts, which are bone-forming cells. Osteocytes play a role in regulating the activity of osteoblasts and osteoclasts.

no. what you are probably looking at (if you have injured yourself) is muscle fibers and fat cells.
The important organic components of bone include collagen, which provides strength and flexibility, and non-collagenous proteins, which regulate mineralization and bone formation. These organic components work together with inorganic minerals like calcium and phosphate to give bone its structure and functionality.

Blood primarily consists of plasma, red blood cells, white blood cells, and platelets. Fibers typically found in connective tissue are found in tissues like tendons, ligaments, and the extracellular matrix of organs.
The cell type that is not found in the areolar connective tissue is chondrocytes. The three main components of connective tissue are ground substance, fibers, and cells.
Connective tissue cells are contained in extracellular matrix composed of collagen and elastin. Examples include fibroblasts in the case of collagen and fibroblasts and smooth muscle cells for elastin.
