Specialized epithelial cells originating fro the nail _____ form your nails.
- A.
Root
- B.
Cells
- C.
Bed
- D.
Base
Correct Answer
A. RootExplanation
Specialized epithelial cells originating from the nail root are responsible for the growth and formation of nails. These cells are located at the base of the nail, where they divide and multiply to produce new cells. As these cells continue to grow and move forward, they push older cells towards the surface, resulting in the formation of the nail plate. Therefore, the correct answer is "root" as it accurately describes the origin and growth of nails.Rate this question:

The outermost layer of skin is known as the:
- A.
Subcutaneous fascia
- B.
Dermis
- C.
Corium
- D.
Epidermis
Correct Answer
D. EpidermisExplanation
The correct answer is epidermis. The epidermis is the outermost layer of the skin and acts as a protective barrier against the external environment. It is composed of several layers of cells, including keratinocytes, which produce the protein keratin that gives the skin its strength and waterproofing properties. The epidermis also contains melanocytes, which produce the pigment melanin that gives color to the skin.Rate this question:

Which of the following are important in regulating body temperature?
- A.
Apocrine glands
- B.
Eccrine glands
- C.
Sebaceous glands
- D.
Lipocytes
Correct Answer
B. Eccrine glandsExplanation
Eccrine glands are important in regulating body temperature. These glands are responsible for producing sweat, which helps to cool down the body when it becomes too hot. Sweat is released onto the skin's surface and evaporates, taking heat away from the body. This process helps to maintain a stable body temperature, especially during physical activity or in hot environments. Apocrine glands, sebaceous glands, and lipocytes do not play a direct role in regulating body temperature.Rate this question:

Warts are caused by:
- A.
Papilloma virus
- B.
Keratin
- C.
Varicella virus
- D.
Staphylococcus
Correct Answer
A. Papilloma virusExplanation
Warts are caused by the papilloma virus. This virus infects the top layer of the skin, causing the skin cells to multiply rapidly and form a wart. The papilloma virus is highly contagious and can be spread through direct contact with an infected person or by touching objects that have been contaminated with the virus. There are different strains of the papilloma virus, with each strain causing different types of warts, such as common warts, plantar warts, and genital warts. Treatment for warts may include topical medications, freezing, or surgical removal.Rate this question:

Hair color is dependent on the amount and type of ______ you produce.
- A.
Minerals
- B.
Follicles
- C.
Melanin
- D.
Keratin
Correct Answer
C. MelaninExplanation
Hair color is determined by the amount and type of melanin produced by the body. Melanin is a pigment that gives color to the hair, skin, and eyes. The more melanin produced, the darker the hair color will be. Different types of melanin, such as eumelanin and pheomelanin, contribute to variations in hair color, ranging from black to blonde. Therefore, melanin is responsible for determining hair color.Rate this question:

Term for any type of hair loss:
- A.
Alopecia
- B.
Baldness
- C.
Melanin
- D.
Hirsutism
Correct Answer
A. AlopeciaExplanation
Alopecia is the correct answer because it is a general term used to describe any type of hair loss, regardless of the cause or location on the body. It can refer to hair loss from the scalp, eyebrows, eyelashes, or any other part of the body. Alopecia can be caused by various factors such as genetics, hormonal changes, autoimmune disorders, or medical treatments. Baldness, melanin, and hirsutism are not appropriate terms for any type of hair loss, as they refer to specific conditions or characteristics related to hair.Rate this question:

The outermost layer of skin, composed largely of dead cells, is known as the:
- A.
Carotene
- B.
Stratum basale
- C.
Stratum corneum
- D.
Vascular layer
Correct Answer
C. Stratum corneumExplanation
The outermost layer of skin is called the stratum corneum. This layer is composed mostly of dead skin cells that have undergone a process called keratinization, where they have become tough and filled with a protein called keratin. The stratum corneum acts as a protective barrier for the underlying layers of skin, preventing water loss and protecting against external factors such as bacteria and UV radiation. It also helps to give the skin its strength and elasticity.Rate this question:

The integumentary system plays an important role in regulating the body's ________.
- A.
Environment
- B.
Composition
- C.
Elasticity
- D.
Temperature
Correct Answer
D. TemperatureExplanation
The integumentary system, which includes the skin, hair, and nails, helps regulate the body's temperature. It does this through processes such as sweating to cool the body down and goosebumps to retain heat. The skin acts as a barrier, protecting the body from external temperature changes and helping to maintain a stable internal temperature. Therefore, the integumentary system plays a crucial role in regulating the body's temperature.Rate this question:

- A.
Scabies
- B.
Pediculosis
- C.
Herpes zoster
- D.
Acne vulgaris
Correct Answer
C. Herpes zosterExplanation
Herpes zoster, also known as shingles, is an eruption of extremely painful vesicles that occur in a band-like pattern along the course of a spinal nerve pathway. It is caused by the reactivation of the varicella-zoster virus, which remains dormant in the sensory ganglia after a primary infection of chickenpox. The vesicles are usually accompanied by burning or tingling sensations and can cause severe pain. Herpes zoster commonly affects older adults and individuals with weakened immune systems.Rate this question:

The condition of yellow jaundice occurs when the body builds up excess __________.
- A.
Carotene
- B.
Melanin
- C.
Freckles
- D.
Bilirubin
Correct Answer
D. BilirubinExplanation
Yellow jaundice, also known as jaundice, is a condition that occurs when the body accumulates an excess of bilirubin. Bilirubin is a yellow pigment that is produced when red blood cells break down. Normally, the liver processes and eliminates bilirubin from the body. However, when there is a problem with the liver or the production of bilirubin exceeds the liver's capacity to process it, bilirubin builds up in the body, leading to the characteristic yellowing of the skin and eyes associated with jaundice.Rate this question:

Collagenous and elastic fibers of the _______ make it possible for the skin to flex with movement of the body.
- A.
Subcutaneous
- B.
Dermis
- C.
Epidermis
- D.
Fascia
Correct Answer
B. DermisExplanation
The dermis is the correct answer because it contains collagenous and elastic fibers that provide strength and flexibility to the skin. These fibers allow the skin to stretch and move with the body, making it possible for the skin to flex. The subcutaneous layer, also known as the hypodermis, is located beneath the dermis and primarily consists of fat cells. The epidermis is the outermost layer of the skin and does not contain collagenous and elastic fibers. Fascia refers to a connective tissue that surrounds and separates muscles and other organs, but it is not directly involved in the flexibility of the skin.Rate this question:

Connective tissue of the skin is developed from __________.
- A.
Melanocytes
- B.
Fibroblasts
- C.
Collagen
- D.
Fascia
Correct Answer
C. CollagenExplanation
The correct answer is collagen because connective tissue, which is found in the skin, is primarily composed of collagen fibers. Collagen provides strength, support, and elasticity to the skin, making it an essential component for maintaining its structure and function. While melanocytes are responsible for producing melanin, the pigment that gives color to the skin, they do not play a direct role in the development of connective tissue. Fibroblasts are cells that produce collagen and other components of the extracellular matrix, so they are involved in connective tissue development. Fascia is a type of connective tissue, but it is not specific to the skin.Rate this question:

After a severe burn, a patient may require a(n) ________, in which skin is removed from an unaffected area of his/her body and moved to the burned area.
- A.
Antibacterial patch
- B.
Heterograft
- C.
Donor site
- D.
Autograft
Correct Answer
D. AutograftExplanation
After a severe burn, a patient may require an autograft, which involves removing skin from an unaffected area of their body and transplanting it to the burned area. This procedure is necessary to promote healing and prevent infection in the burned area. Autografts are preferred over other options like heterografts or donor sites because they have a lower risk of rejection and provide a better match in terms of tissue type and color.Rate this question:
