What structures are in the dermis that are not in the epidermis?

Dermis. The dermis might be considered the “core” of the integumentary system (derma- = “skin”), as distinct from the epidermis (epi– = “upon” or “over”) and hypodermis (hypo– = “below”). It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands.

How is the dermis different from the 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 is only found in the dermis?

Structures found in the dermis include: Connective tissues, specifically collagen and elastin. Blood capillaries (the smallest of blood vessels) and other small vessels. Lymph vessels. Sweat glands.

What structures are found in the dermis?

The dermis contains nerve endings, sweat glands and oil glands (sebaceous glands), hair follicles, and blood vessels. The nerve endings sense pain, touch, pressure, and temperature.

What does the epidermis not have?

The Epidermis. The epidermis is composed of keratinized, stratified squamous epithelium. It is made of four or five layers of epithelial cells, depending on its location in the body. It does not have any blood vessels within it (i.e., it is avascular).

What do epidermis and dermis have in common?

A number of components are common to both the dermis and epidermis. These are: pores, hair, sebaceous glands, and sweat glands. Pores are formed by a folding-in of the epidermis into the dermis.

What layer is between the epidermis and dermis?

The stratum basale (also called the stratum germinativum) is the deepest epidermal layer and attaches the epidermis to the basal lamina, below which lie the layers of the dermis. The cells in the stratum basale bond to the dermis via intertwining collagen fibers, referred to as the basement membrane.

What structures are found in the papillary layer?

The papillary layer is defined by rete ridges (i.e. papillae) which are finger-like structures extending into the epidermis and contains thin collagen fibres, sensory nerve endings, cytoplasms and a rich network of blood capillaries.

Which of the following tissues can be found within the dermis of the integument?

The epidermis is composed of epithelial tissue, and the dermis is connective tissue.

What types of tissues make up the dermis What are the functions of these tissues?

Blood vessels, smooth muscle tissue, and nervous tissue are found in the dermis. What are the functions of these tissues? The Connective Tissues give the dermis toughness and elasticity. The Smooth Muscle Tissue can wrinkle the skin.

Which structures are dermal papillae?

Dermal papillae are the protrusions of dermal connective tissue into the epidermal layer. Rete ridges are the extensions of epidermis into the dermal layer. This undulating pattern is more apparent in thick skin of the hands and palms. There is no clear line of distinction between the papillary and reticular dermis.

Which is not part of the skin?

Hypodermis. The hypodermis (also called the subcutis or subcutaneous layer) functions to connect the integument (epidermis and dermis) to the underlying muscles and organs. The hypodermis is not considered part of the skin, but has several important functions.

Which of the following is not a function of skin?

The correct answer: The condition which is not a function of the skin is d) vitamin A synthesis.

What does epidermis consist of?

The epidermis of the skin is a constantly renewing stratified squamous epithelium. It consists mostly of keratinocytes, but also of Langerhans cells, melanocytes, and Merkel cells resting on a supporting dermis that contains the nerve and vascular networks, which nourish the epidermis.

Are all layers of the epidermis stratified squamous tissue?

The epidermis is composed of keratinized, stratified squamous epithelium. It is made of four or five layers of epithelial cells, depending on its location in the body. ... The cells in all of the layers except the stratum basale are called keratinocytes.
