This tough protein is found in hair and nails for structural stability.

• melanin

• sebum

• keratin

• Merkle cells

This skin pigment protects the body from harmful UV rays

• melanin

• sebum

• keratin

• Merkel cells

Which of the following is composed of primarily flattened dead cells?

• hypodermis

• epidermis

• dermis recticular layer

The 5 layers of the epidermis from outer to inner layers are: Stratum -

• basale, spinosum, granulosum, lucidium, corneum

• corneum lucidium, spinosum, granulosum, basale

• corneum, lucidium, granulosum, spinosum, basale

• basale, granulosum, spinosum, lucidium, corneum

This layer of the epidermis (a stratum) is found only on the palms and the soles of your feet. It is an extra thicker layer to protect those highly used areas.

• corneum

• lucidium

• granulosum

• spinulosum

Which of the following cells make keratin?

• Merkel cells

• sebaceous glands

• epidermal dendritic cells

• keratinocytes

These specialized cells work with the immune and nervous system to fight off foreign bacteria and initiating an immune response.

• Merkel cells

• sebaceous glands

• melanocytes

• epidermal dendritic cells.

These cells function as a touch receptor for your epidermis.

• keratinocytes

• Merkel cells

• sudoriferous glands

• sebaceous glands

Which of the following has the layers of the integumentary system in the correct order? (From outer to inner)

• Hypodermis, Dermis, Epidermis

• Epidermis, Dermis, Hypodermis

• Dermis, Epidermis, Hypodermis

• Hypodermis, Epidermis, Dermis

This part of the dermis is responsible for the ridges of your fingerprints.

• stratum lucidium

• Merkel cells

• papillary layer

• recticular layer
