Question 8

Superficial skin layer composed of stratified squamous epithelium

Answer 8

Answer 10

Elastin

Question 11

Sheets of hardened keratinocytes that reinforce and protect the distal ends of fingers and toes

Answer 11

Nails

Question 12

Deep to the dermis; holds skin to underlying tissue and stores fat

Answer 12

Hypodermis

Question 13

Serous membrane layer that lines the inside wall of the cavity

Answer 13

Parietal layer

Question 14

Cells that make up of 90% of the epidermis; produce and store the protein keratin

Answer 14

Keratinocytes

Question 15

Tightly packed keratinocytes that grow from the root in a hair follicle; protect the skin from UV radiation

Answer 15

Hair

Question 16

Sheath in the dermis from which hair grows

Answer 16

Hair follicle

Question 17

Wet membranes that line body cavities that open to the exterior; often adapted for absorption or secretion

Answer 17

Mucous membranes

Question 18

Superficial layer of the dermis that borders the epidermis; contains dermal papillae, capillary loops, pain, and touch receptors

Answer 18

Papillary layer

Question 19

Cells in the lower layer of the epidermis that produce the pigment melanin

Answer 19

Melanocytes

Question 20

Protein that makes cells tough, scaly, and water resistant

Answer 20

Keratin

Question 21

Deep layer of the dermis that contain blood vessels, sweat & oil glands, deep pressure receptors, and phagocytes

Answer 21

Question 22

Projections that hold the epidermis and dermis together

Answer 22

Dermal papillae

Question 23

Serous membrane layer that covers the outside of an organ

Answer 23

Visceral layer

Question 24

Membranes that line body cavities that are closed to the exterior; occur in pairs; secrete serous fluid

Answer 24

Serous membranes

Question 25

Type of sweat that is concentrated in axillary and genital areas; produce sweat that contains fatty acids and proteins; begin to function at puberty

Answer 25

Apocrine sweat glands

Question 26

Pigment that gives skin its color; protect skin from UV radiation

Answer 26

Melanin

Question 27

Small bands of smooth muscle that connect hair follicles to the dermis; contraction pulls the hair upright and causes bumps on the skin's surface
