Question 1

When there is damage to the skin, a sequence of events is set into motion that repairs the skin to its normal, or near normal, state in terms of structure and function. In other words, the repair process attempts to restore
A)apoptosis
B)homeostasis
C)kinesis
D)cytolysis
E)osmosis

Accepted Answer

The repair process aims to restore homeostasis, which refers to the maintenance of a stable environment inside the body, including the skin. This process involves various cellular and molecular mechanisms that work together to address the damage and restore normal function. Apoptosis, kinesis, cytolysis, and osmosis may occur during the repair process, but they are not the main objective or outcome.

Question 2

Which of the labeled layers of the epidermis shown in the diagram produce lamellar granules containing the "water-proofing" chemicals found in skin? 
A)A
B)B
C)C
D)D
E)E

Accepted Answer

The labeled layer C, stratum granulosum, is responsible for producing lamellar granules containing the "water-proofing" chemicals found in skin. These granules are composed of lipids and proteins and play a crucial role in forming the barrier function of the skin.

Question 7

Which of the labeled epidermal cells in the diagram helps the immune system to recognize foreign microbes present in the skin? 
A)F
B)G
C)H
D)I
E)J

Accepted Answer

The labeled epidermal cell H is a dendritic cell, which plays a critical role in the immune system by recognizing foreign microbes and activating immune responses against them.

A)C
B)D
C)E
D)F
E)I

Accepted Answer

The answer of Which of the labeled accessory structures in...

Question 9

Which of the labeled epidermal layers in the diagram is found in "thick skin" but not in "thin skin"? 
A)A
B)B
C)C
D)D
E)E

Accepted Answer

The answer of Which of the labeled epidermal layers in...

Question 10

Which of the following processes represents the last stage of epidermal wound healing?
A)A blood clot forms that fills and seals the open wound.
B)The stem cells divide to form new strata.
C)Vasodilation delivers immune cells to the wound.
D)Fibroblasts lay down collagen fibers within the wound to form scar tissue.
E)The migrating basal cells meet and start growing to build new strata.

Accepted Answer

The migrating basal cells meet and start growing to build new strata represents the last stage of epidermal wound healing, also known as epithelialization. During this stage, the newly formed skin cells migrate across the wound bed to close the wound and create a new epithelial layer. This completes the process of epidermal wound healing.
