If you could drive straight down, into a tunnel bored through the crust of the planet, you'd hit this molten mess in about an hour. It's called the asthenosphere - a sluggish sea, several hundred miles thick, on which floats the Earth's cool epidermis - the so-called tectonic plates.

The arteries are found in nearly every part of the animal body, with the exception of the hairs, nails, and epidermis; and the larger trunks usually occupy the most protected situations, running, in the limbs, along the flexor side, where they are less exposed to injury.

The appendages of the skin are the nails, the hairs, the sudoriferous and sebaceous glands, and their ducts. The nails and hairs are peculiar modifications of the epidermis, consisting essentially of the same cellular structure as that membrane.

In humans, 'epidermis' refers to skin and implies a biological or clinical context.

Human Biology

'Epidermis' indicates the skin's role as a protective barrier against the environment.

Protection Role

The 'epidermis' is the part of our skin we see, with no blood vessels present.

Visible Layer

'Epidermis' in plants relates to the outermost tissue, vital for protection.

Plant Anatomy

Many plants have a waxy layer on their epidermis called the cuticle.

Cuticle Presence

The thickness of the 'epidermis' can vary greatly among different plant types.

 such as sweating, feeling heat and cold, and growing hair. But after a deep cut or wound, the newly healed skin will look different from the surrounding area, and may not fully regain all its abilities for a while, or at all. To understand why this happens, we need to look at the structure of the human skin. The top layer, called the epidermis,

 though it can be mitigated by the use of sunblock. But since the dermal cells are relatively stable, much of the ink will remain deep in the skin for a person's whole life.

 Now, if you look at our aging process, the aging process is in fact the loss of water from the upper epidermis, resulting in wrinkling as we know it, especially women, we are so conscious of this. And this plant, in fact, is giving the cosmetic chemists very important ingredients

 As new cells grow at the base, old cells are pushed up and form a harder layer that's difficult for water or microbes to cross. Our keratinocytes also synthesize vitamin D from the sun, which is vital for our health. Other important cells in the epidermis include melanocytes,

 The body detects these breaches and responds defensively, causing the inflammation that gives dandruff it’s itch. It also makes the skin cells proliferate to repair the damaged barrier. Usually, our skin’s outer surface, or epidermis,
