What are the two zones of dermis?
The dermis is divided into two layers: the papillary dermis and the reticular dermis. The papillary dermis is the superficial layer, lying deep to the epidermis. The papillary dermis is composed of loose connective tissue that is highly vascular.
What two layers are the dermis composed of?
The dermis has connective tissue, blood vessels, oil and sweat glands, nerves, hair follicles, and other structures. It is made up of a thin upper layer called the papillary dermis, and a thick lower layer called the reticular dermis.
What is the dermis primarily composed of?
The dermis consists of dense, fibrous connective tissue whose predominant connective tissue component is collagen. The texture of collagen fibers serves as the basis for recognizing two layers of dermis.
What are the zones of the dermis?
The dermis has two main zones, the papillary dermis and the reticular dermis. The subcutaneous fat is an important layer and plays a role in shock absorption, energy storage, and maintenance of body heat.
What are the two layers of the dermis and what is their function?
The papillary layer, the upper layer of the dermis, contains a thin arrangement of collagen fibers. The lower layer, known as the reticular layer, is thicker and made of thick collagen fibers that are arranged parallel to the surface of the skin.

What is the two layers of the skin?
The epidermis and the dermis are the top two layers of skin in your body. The epidermis is the top layer, and the dermis is the middle layer. The dermis exists between the epidermis and the hypodermis. While the epidermis is the thinnest layer of skin, the dermis is the thickest layer of skin.
What is the dermis primarily composed of quizlet?
The dermis is composed primarily of connective tissue and the epidermis is composed primarily of epithelium. The epidermis is deeper than the dermis. Skin color is mainly due to cells located in the upper part of the dermis; the cells of the epidermis are colorless.
Which structure is found in the dermis quizlet?
Hair follicles, nerve endings, glands, smooth muscle, blood vessels, & lymphatic are all found in the dermis as well, creating a rich & interesting tissue community.
What tissue forms most of the dermis quizlet?
What types of tissues make up the dermis? The papillary layer is areolar connective tissue, and the reticular layer is dense irregular connective tissue. Blood vessels, smooth muscle tissue, and nervous tissue are found in the dermis.
What is epidermis layer of skin?
The epidermis is the thin outer layer of the skin. It consists of 3 types of cells: Squamous cells. The outermost layer is continuously shed is called the stratum corneum.
What type of tissue is found in the dermis of the skin quizlet?
The dermis has connective tissue, smooth muscle tissue, and nervous tissue.
What are the two main layers of the skin quizlet?
Epidermis and dermis are the primary skin layers.
Which of the following are present in the dermis quizlet?
The dermis is composed of two layers: a thin, superficial PAPILLARY (dermis) LAYER & the thick RECITULAR (dermis)LAYER. Hair follicles, nerve endings, glands, smooth muscle, blood vessels, & lymphatic are all found in the dermis as well, creating a rich & interesting tissue community.
Which of the following is found in the dermis layer of skin quizlet?
The dermis consists of connective tissue, nerve cells, muscle fibers, sweat glands, oil glands, and hair follicles.
What are the two layers of the dermis quizlet?
Papillary and Reticular: Two Layers of the Dermis.
What are the 2 major layers of the skin?
What is the difference between dermis and epidermis?
The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
What are the two main cells found in the epidermis?
Keratinocytes (skin cells) Melanocytes (pigment-producing cells)
What tissue types are found in the dermis?
Your dermis contains collagen and elastin, which help make your dermis thick and supportive of your skin’s overall structure. All of your connective tissues, nerve endings, sweat glands, oil glands and hair follicles exist in your dermis.
What are the 2 main cells found in the epidermis?
What types of tissues make up the dermis quizlet?
How many layers make up the dermis quizlet?
2 layers of Dermis Flashcards | Quizlet.
How many layers is the skin composed of?
three layers
It is made up of three layers, the epidermis, dermis, and the hypodermis, all three of which vary significantly in their anatomy and function. The skin’s structure is made up of an intricate network which serves as the body’s initial barrier against pathogens, UV light, and chemicals, and mechanical injury.
Which layer is composed primarily of dense irregular tissue?
Layers of Skin. The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures.
