Answer 17

The three layers of the skin are the epidermis, the dermis, and the subcutaneous layer (hypodermis).

Answer 18

The outer layer of the skin. It provides a waterproof barrier and protects underlying structures from ultraviolet rays, harmful chemicals, and pathogens. The epidermis has several distinct layers. These layers are the stratum corneum, stratum lucidem, stratum granulosum, stratum spinosum, and the stratum basale.

Answer 19

The inner layer of the skin. It is composed of dense connective tissue with collagen fibers, which gives the skin strength and elasticity. It is well supplied with blood vessels and nerves. It also contains the other skin organs, sweat glands, oil glands, hair follicles, and nail roots.

Answer 20

The subcutaneous layer is not actually part of the skin, but it helps to anchor the skin to the underlying structures. This layer also guards against heat loss and provides insulation. This layer is primarily composed of adipose tissue, comprised of lipocytes or fat cells. The location and thickness of subcutaneous tissue differ by gender.

Answer 21

The outermost layer of the epidermis. It consists of dead keratinocytes that are constantly being shed. The complete cell turnover from basal cell to stratum corneum takes about fours weeks.

Answer 22

This layer only exists on the palms of the hands and soles of the feet.

Answer 23

This layer is made up of keratinocytes that have moved from the squamous layer. As these cells move closer to the skin’s surface, they flatten, eventually dying out.

Answer 24

This is the thickest layer of the epidermis. Keratinocytes here produce keratin, which is a protective protein that makes up skin, nails, and hair.

Answer 25

The cells in this layer are constantly dividing and being pushed toward the surface. This layer is also home to melanocytes that produce melanin, the pigment responsible for skin color.

Answer 26

Tiny could glands found on almost all body surfaces. There are two types of sweat glands; eccrine and apocrine. Both eccrine and apocrine are activated by nerves. These nerves respond to various stimuli, including temperature, hormones, emotions, and physical activity.

Answer 27

Most sweat glands are eccrine sweat glands, which are found in large numbers on the soles of the feet, the palms, the forehead and cheeks, and in the armpits. Eccrine glands open directly onto the surface of the skin. Eccrine glands secrete an odorless, clear fluid that helps the body control its temperature by promoting heat loss through evaporation.

Answer 28

Open into hair follicles in the scalp, armpits, and genital region, leading to the surface of the skin. They produce a thick fluid. When this fluid comes in contact with bacteria on the skin’s surface, it produces a characteristic “body odor”.

Answer 29

Microscopic organs in the skin that are connected to hair follicles. They secrete an oily substance called sebum that is released through ducts opening into the hair follicles. The sebum then moves onto the surface and lubricates and waterproofs the skin.
