What else can I help you with?
Skin is attached to underlying structures?
dermis
These structures are formed by portions of the epidermis that extend into the dermis and are adjacent to dermal papillae?
Hairs are structures are formed by portions of the epidermis that extend into the dermis and are adjacent to dermal papillae.
What are similarities in the structures found in the epidermis with the structures found in the dermis?
There is no structural similarity between the epidermis and the dermis. They are both a part of the integumentary system but are vastly different in structure and makeup.
What structures doe the dermis contain?
The dermis contains nerves, blood vessels, sweat glands, hairs, and oil glands.
What structures are in the dermis that are not in the epidermis?
The dermis contains many nerves and blood vessels, while the epidermis does not. The dermis is so close to the epidermis that even shallow cuts may hurt.
What are the components of the dermis and their functions?
The components of skin. Epidermis is the top layer. (Epi=above, -dermis=skin). The dermis is the true skin and middle layer. The hypodermis is below the dermis. (hypo=below)
What are strands of hair grow within the dermis in structures called?
Pores
What are skin markings that occur where the dermis is secured to deeper structures?
flexure lines
What term describes the tissue layer directly below epidermis?
The Papillary Layer which is a part of the Dermis
What layer of the skin contains the accessory structures?
The accessory structures of the skin, such as hair follicles, sweat glands, and sebaceous glands, are primarily found in the dermis layer. The dermis lies beneath the epidermis and provides support and nourishment to the skin, housing these structures within its connective tissue. The dermis also contains blood vessels, nerves, and other components that contribute to the skin's functionality.
What layer of the integument functions in the storage of lipid reserves?
reticular layer of the dermis
What is the upper layer of the dermis that forms dermal papillae?
The upper layer of the dermis that forms dermal papillae is known as the papillary dermis. This layer is composed of loose connective tissue and contains small, finger-like projections called dermal papillae, which interdigitate with the epidermis. These structures enhance the surface area for exchange of nutrients and waste, and they contain capillaries, nerve endings, and sensory receptors, contributing to the skin's tactile functions.
