yes the dermis contains both elastic and collagen fibers
Elastic fibers
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.
The skin is the organ that contains the dermis.
Collagen fibers makes up 75% of the dermis, which is the inner layer of skin that protects the body from physical stress, it also contains elastic fibers, and ground substances.
The reticular layer of the dermis
The dermis, the layer just below the epidermis, is made up of collagen, elastin fibers, and blood vessels. Together they make your skin spongy and plump.
Capillaries
Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.
The fibers found in the dermis are elastic fibers and collagen type I.
Fibers in the dermis are produced by fibroblasts.
