Question 15

Epidermis:

Answer 15

The outermost layer of skin, composed of stratified squamous epithelium. It provides a barrier to environmental damage and prevents water loss.

Question 16

Dermal Papillae

Answer 16

Projections of the dermis into the epidermis that contain blood vessels and nerve endings. They help anchor the two layers together and increase the surface area for exchange.

Question 17

Dermis

Answer 17

The thick layer beneath the epidermis, consisting of connective tissue, blood vessels, nerves, and hair follicles. It provides strength, elasticity, and housing for various skin structures.

Question 18

Subcutaneous Layer (Hypodermis)

Answer 18

The deepest layer of skin, made of loose connective tissue and fat. It provides insulation, cushioning, and energy storage.

Question 19

Thick Skin

Answer 19

Found on the palms of the hands and soles of the feet, thick skin has a thicker epidermis and lacks hair follicles. It has more layers of keratinocytes for protection.

Question 20

Thin Skin

Answer 20

Covers most of the body and contains hair follicles, sebaceous glands, and fewer layers of keratinocytes compared to thick skin.

Question 21

Eccrine Sweat Glands

Answer 21

Sweat glands that are found throughout the body, primarily in the palms, soles, and forehead. They help regulate body temperature through perspiration.

Question 22

Arrector Pili Muscle (Piloerector Muscle)

Answer 22

Small muscles attached to hair follicles that contract to make hair stand up (goosebumps) in response to cold or fear.

Question 23

Hair Root

Answer 23

The part of the hair embedded in the follicle beneath the skin surface, responsible for hair growth.

Question 24

Hair Shaft

Answer 24

The visible part of the hair that extends above the skin surface.

Question 25

Sebaceous Oil Gland

Answer 25

Glands associated with hair follicles that secrete sebum, an oily substance that lubricates the skin and hair, helping to prevent dryness.
