It is divided into two layers the superficial area adjacent to the epidermis called the papillary region and a deep thicker area known as the reticular dermis.

Anatomy of dermis. Clinical anatomy for dummies. The dermis is tightly connected to the epidermis through a basement membrane. This lower layer of the skin contains collagen and elastic fibers that give strength to the skin.

This layer also contains melanocytes which are the cells that produce skin coloring. Skin has three layers. The papillary dermis which lies superficially the recticular dermis which lies deeper.

This layer is also where the vasculature and nerves live. Apocrine and endocrine glands. The middle layer the dermis is fundamentally made up of the fibrillar structural protein known as collagen.

Meissner corpuscles and lamellar corpuscles that transmit the sensations of touch and pressure. The dermis or corium is a layer of skin between the epidermis and subcutaneous tissues that primarily consists of dense irregular connective tissue and cushions the body from stress and strain. The hypodermis also called the subcutaneous layer or superficial fascia is a layer directly below the dermis and serves to connect the skin to the underlying fascia fibrous tissue of the bones and muscles.

The dermis contains several specialized cells and structures including. The epidermis the outermost layer of skin provides a waterproof barrier and creates our skin tone. Broadly the dermis can be divided into two layers.

Picture of the skin. The thickness of these layers varies considerably depending on the geographic location on the anatomy of the body. A thin upper layer known as the papillary dermis.

The der mis lies on the subcutaneous tissue or panniculus which contains small lobes of fat cells known as lipocytes. The deeper subcutaneous tissue hypodermis is made of fat and connective tissue. The fin rays of fishes are dermal derivatives as are many types of pigment cells.

Blood vessels and nerve endings. Anatomy and function of the dermis anatomy and structure. The dense inner layer of skin beneath the epidermis composed of connective tissue blood and lymph vessels sweat glands hair follicles and an elaborate sensory nerve network.

The dermis is the thickest layer of skin and arguably the most. Structural components of the dermis are collagen elastic fibers. The papillary layer the upper layer of the dermis.

The dermis from its earliest evolutionary appearance has been a depository of bone as expressed in dermal armour primitive fishes scales fishes and certain amphibians and plates crocodile lizard turtle armadillo. The dermis beneath the epidermis contains tough connective tissue hair follicles and sweat glands.
