In this integumentary system quiz with questions and answers, we’ll be taking a look at an often ignored biological system of our bodies – the integumentary system, whereby the skin and its associated appendages act to protect our bodies from harm. Not only that but the integumentary system is also integral for the regulation of various systems in our body, like the heat regulation system through sweating and more! Let’s find out right now how much you actually know about this amazing system just by answering the following questions. Have fun with the quiz!

Questions and Answers

1.

Which layer accounts for 3/4 of the epidermal thickness?
- A.
  
  Corneum
- B.
  
  Basale
- C.
  
  Spinosum
- D.
  
  Lucidium
Correct Answer
A. Corneum

Explanation
The corneum layer is the outermost layer of the epidermis and is responsible for providing protection to the underlying layers. It is composed of dead skin cells that are constantly being shed and replaced. This layer is thick and accounts for approximately 3/4 of the total epidermal thickness.

____________ is the most dangerous type of skin cancer.

Correct Answer
Melanoma

Explanation
Melanoma is the most dangerous type of skin cancer because it develops in the cells that produce melanin, which gives color to the skin, hair, and eyes. It is more likely to spread to other parts of the body if not detected and treated early. Melanoma can be caused by excessive exposure to UV radiation from the sun or tanning beds, a history of sunburns, family history of melanoma, and having many moles or atypical moles. It is crucial to protect the skin from sun exposure, regularly check for any changes in moles or skin, and seek medical attention if any suspicious growths are noticed.

  3
- C.
  
  7
- D.
  
  None of the above
Correct Answer
B. 3

Explanation
The major three layers of skin are as follow: 1). The epidermis 2). The dermis 3). The hypodermis

These three layers, the epidermis, dermis, and the hypodermis are vary significantly in their anatomy and function.

Which cells of the epidermis produce fibrous protein keratin?
- A.
  
  Melanocytes
- B.
  
  Langerhans' Cells
- C.
  
  Merkel cells
- D.
  
  None of the above
Correct Answer
D. None of the above

Explanation
The cells of the epidermis that produce fibrous protein keratin are called keratinocytes. Melanocytes produce the pigment melanin, Langerhans' cells are involved in immune responses, and Merkel cells function as touch receptors. Therefore, none of the above options are correct.

Which glands are not active until puberty?

Correct Answer
Apocrine glands, apocrine gland

Explanation
Apocrine glands are not active until puberty. These glands are a type of sweat gland that are located in specific areas of the body, such as the armpits and groin. They secrete a thick, odorless substance that becomes odorous when it comes into contact with bacteria on the skin's surface. During puberty, hormonal changes stimulate the apocrine glands to become active, resulting in increased sweat production and body odor. Therefore, it can be concluded that apocrine glands are not active until puberty.

Dilation (____________) and constriction (____________) occurs to regulate body temperature.

Correct Answer
cooling; warming

Explanation
Dilation refers to the expansion of blood vessels, allowing more blood to flow to the skin's surface, which helps to cool the body down. On the other hand, constriction refers to the narrowing of blood vessels, reducing blood flow to the skin's surface, which helps to conserve heat and warm the body. Therefore, dilation and constriction are mechanisms that the body uses to regulate body temperature by either cooling or warming it.

What type of burn only affects the epidermis and upper regions of the dermis?

Correct Answer
2nd degree, second degree, 2 degree

Explanation
A second-degree burn, also known as a partial-thickness burn, only affects the epidermis (the outermost layer of the skin) and the upper regions of the dermis (the layer beneath the epidermis). This type of burn typically causes redness, blistering, and pain. It does not penetrate deeper into the skin layers like a third-degree burn. Therefore, the correct answer is 2nd degree, second degree, or 2 degree.

The papillary layer of the dermis consists of areolar connective tissue with collagen and elastic fibers.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The papillary layer of the dermis is composed of areolar connective tissue, which contains collagen and elastic fibers. This layer is located just below the epidermis and is responsible for providing support and nourishment to the overlying epidermis. Collagen fibers give strength and structure to the skin, while elastic fibers allow the skin to stretch and recoil. Therefore, the statement that the papillary layer of the dermis consists of areolar connective tissue with collagen and elastic fibers is true.
