Answer 2

Dense irregular connective tissue

Question 3

What type of tissue is found in the Hypodermis?

Answer 3

Adipose connective tissue

Question 4

Layers of the Epidermis:

Stratum Corneum

Answer 4

(1) Very outside of skin. Flakes off as new cells grow underneath

Question 5

Layers of the Epidermis:

Stratum Lucidum

Answer 5

(2) Only found in callused skin

Question 6

Layers of the Epidermis:

Stratum Granulosum

Answer 6

(3) Granules of keratin protein forming inside cells

Question 7

Stratum Spinosum

Answer 7

(4) second layer of “squashed
cells”

Question 8

Layers of the Epidermis:

Stratum Basale

Answer 8

(5) new cells of the epidermis at the base level

Question 9

Layers of the Epidermis:

Papillary layer of the dermis

Answer 9

(6) contains capillaries to feed the epidermis

Question 10

Reticular layer

Answer 10

(7) This layer is between the Stratum Basale and the Hypodermis

Question 11

Hypodermis

Answer 11

(8) This area is below the Stratum Basale

Question 12

Cells of the Epidermis:

Keratinocytes

Answer 12

• begin life in the stratum basale and die over the course of moving into outer
  layers.
• Creates a force pushing outward so pathogens cannot move into the skin
• Keratin protein found within these cells that creates the waterproof barrier of our
  skin
