What else can I help you with?
what does Ulcers mean?
A breech of an epithelial surface exhibiting complete loss of the epidermis and often portions of dermis and subcutaneous fat.
How could a dental checkup not reveal gum disease that causes a nagging toothache and possible tooth loss?
when the infection is deep in and not on the surface
What layer is more cellular than the other- Dermis or Epidermis?
The dermis is more cellular than the epidermis. The dermis contains a variety of cells, including fibroblasts, macrophages, and mast cells, which play important roles in maintaining the structure and function of the skin. In contrast, the epidermis primarily consists of keratinocytes, which are responsible for producing the protein keratin that helps to form the skin's protective barrier.
What do arterioles in the dermis do in a cold environment?
They will allow the blood vessels to widen so that more heat loss can occur through evaporation. This is vasodilation.
The thin outermost layer of skin?
The thin outermost layer of skin is called the epidermis. It acts as a protective barrier against external factors and helps regulate water loss from the body. The epidermis contains different types of cells, including keratinocytes and melanocytes.
How the surface area affects heat loss?
Heat loss of water: The surface area effects the the rate of heat loss because the rate of heat loss increases if the surface are is higher. How: The water is spread out into a bigger space meaning the
What glands prevent water loss?
The sebaceous glands, also known as oil glands, prevent water loss. These glands are found in the dermis, and secrete sebum to protect the outer layer of the skin.
Wrinkles and sagging skin in elderly individuals are the result of?
Gravity and the loss of elasticity and adipose tissue in the skin........which naturally happens over time...........
How is the dermis different from the epidermis?
Alrighty the epidermis, the upper or outer layer of the skin, is a tough, waterproof, protective layer. The dermis, or inner layer, is thicker than the epidermis and gives the skin its strength and elasticity.
Skin markings that occur where the dermis is secured to deeper structures is called?
Skin markings that occur where the dermis is secured to deeper structures are called wrinkles. They are caused by a decrease in collagen and elastin production in the skin with age, leading to a loss of skin elasticity.
Describe how the arterioles in the dermis respond to heat cold and stress?
Arterioles dilate in warm environments (vasodilation). Dilate means to open. Vasodilation is a process in which the increased blood flow through the dermis brings excess heat close to the body surface to be radiated to the environment. Arterioles constrict in cold environments (vasoconstriction). Constrict means to close. Vasoconstriciton is a process in which the decreased blood flow through the dermis keeps heat within the core of the body. Both take place to maintain homeostasis. In stressful situations, vasoconstriction takes place. It will shunt in the dermis or redirect blood to more vital organs such as the muscles, heart and brain.
What are leaf epidermal cells adapted for tell meeeee plzzzz?
Dermis is covered by epidermis. There are cells, which are tightly packed. Epidermis is covered with waxy coating to prevent the water loss. The surface area of the leaves is very large. That is needed to absorb more and more light. This large surface area will lose lot of water. That is risky. So the adaptation. Tried to tell you. Though I am not a botanist.
