What region of the skin are the specialized nerve endings found?
Specialize nerve endings are found within the dermis of the skin.
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.
In what organ would you find the most nerve tissue?

The epidermis and the dermis make up what membrane?
The skin, our largest organ is a cutaneous membrane and in addition to hair and nails make up the integumentary system. It is made up of various layers within 2 most distinctive layers, ther dermis and epidermis. The dermis holds all the blood vessels, glands, nerve endings and fibres (elastic/collagen). The epidermis derives it's nutrition from the dermis and is constantly shed through the process of keratinisation. Functions of the skin is protection, heat regulation, sensation, excretion, secretion, absorption and immunity. The epidermis reflects our true health as it's appearance is dependant on a healthy blood and nutrition supply from the dermis. Go figure, our first line of defense against the environment is something many of us neglect...
What layer of skin are capillaries in?
The capillaries are contained within the dermis and and nutrients that the epidermis requires diffuses up to it.
