Instructions

There are 5 layers to the epidermis & you will represent each layer within your drawing. Add each of the following epidermal layers and color each as indicated below. Be sure to make the thickness of each layer proportional to what it is in real life.stratum basale (dark purple) stratum spinosum (orange)stratum granulosum (pink) stratum corneum (white w/

black dashes)

Black stars* will represent Melanocytes which produce pigment. Add stars to the Stratum basale, spinosum and granulosum.

Green plus signs (+) will represent Keratinocytes which water repel the skin. Add + to 4 layers.

Red dollar signs ($) will represent Langerhans cells which defend against pathogens. Add $ to Stratum spinosum

Color each of the following nerve endings as directed below. free dendrite nerve endings (gray) Merkel discs “light touch”

receptor (red)

Write the function of the epidermis, dermis & hypodermis. Make sure to leave room in your epidermis for the hair root to pass through &

outside of the epidermis. Label the hair shaft.

Each of the following structures is found within the dermis.

Nerves (gray) Meissner's Corpuscles (light brown)

Pacinian's Corpusles (light pink) Sebaceous glands (dark pink)

Arrector pili muscles (red) Sudoriferous glands (dark green)

Krause's end bulbs (light blue) Ruffini's Corpuscles (orange)

Arteries - left (red) Veins -right (blue)Capillaries(left½ red; right½ blue) Areolar Connective tissue(papillary

layer) (light green)Hair Root (dark brown) Dense Connective tissue(reticulary layer)

(light purple)

Write the function of the dermis in the space above the coloring.

Tape the epidermis above the dermis.Label all structures with their scientific names & functional name.

(i.e. write oil gland /sebaceous gland)

Each of the following structures is found within the hypodermis.

Adipose tissue (yellow) Areolar tissue (light green)

Arteries - superior (red) Veins - inferior (blue)

Capillaries (left½ red; right½ blue) Sudoriferous gland (dark green)

Nerves grayTape the hypodermis below the dermis.Write the function of the hypodermis.
