2. Inner dermis

Question 3

Superficial epithelium [epithelial tissue]

Answer 3

outer epidermis

Question 4

connective tissues

Answer 4

Question 5

Accessory structures that originate in the dermis and extend through the epidermis to skin surface

Answer 5

Hair, nails and multicellular exocrine glands

Question 6

loose connective tissue that lies below the dermis

Answer 6

Hypodermis

Question 7

an avascular stratified squamous epithelium

Answer 7

epidermis

Question 8

contain large amounts of keratin and are the most abundant cells in the epidermis

Answer 8

keratinocytes

Question 9

covers most of the body and has four layers of keratinocytes

Answer 9

thin skin

Question 10

covers the palms of the hands and soles of the feet and has five layers of keratinocytes

Answer 10

thick skin

Question 11

the five strata of keratinocytes in thick skin

Answer 11

1. stratum basale
2. stratum spinosum
3. stratum granulosum
4. stratum lucidum
5. stratum corneum

Question 12

attached to basement membrane by hemidesomomes and forms a strong bond between the epidermis and dermis

Answer 12

stratum basale

Question 13

ridges formed by the stratum basale like fingerprints

Answer 13

epidermal ridges

Question 14

tiny mounds that increase the area of basement membrane and strengthens the attachment between the epidermis and dermis

Answer 14

dermal papillae

Question 15

cells found in hairless skin that respond to touch

Answer 15

merkel cells

Question 16

contain the pigment melanin and are scattered throughout stratum basale

Answer 16

melanocytes

Question 17

“spiny layer” that is produced by division of stratum basale

Answer 17

stratum spinosum

Question 18

“grainy layer” stops dividing and starts producing keratin and keratohyalin

Answer 18

stratum granulosum

Question 19

a tough fibrous protein that makes up hair and nails

Answer 19

keratin

Question 20

dense granules that cross link keratin fibers

Answer 20

keratohyalin

Question 21

“clear layer” that are found only in thick skin and covers the stratum granulosum

Answer 21

stratum lucidum

Question 22

“horn layer” that is the exposed surface of the skin that has 15-30 layers of keratinized cells. It is water resistant and is shed/replaced every 2 weeks

Answer 22

stratum corneum
