skin’s pigment?
1. A)
Keratinocytes
2. B)
Melanocytes
3. C)
Tactile corpuscles
4. D)
Dendritic cells
Answer: B
Explanation: Keratinocytes begin in the stratum basale and

As they divide, they push the older cells up toward the surface. Melanocytes
produce skin pigments called melanin. Tactile corpuscles are cells that serve
as receptors for fine touch only. Dendritic cells are immune system cells found
in the stratum spinosum and the stratum granulosum. They alert the body’s
immune system to the invasion of pathogens that could make it through the
stratum corneum.

keratinocytes?
1. A)
Melanin
2. B)
Keratin
3. C)
Sebum
4. D)
Corneum
Answer: B
Explanation: Keratinocytes begin in the stratum basale and
make up the majority of epidermal cells. Their purpose is to grow and divide.
As they divide, they push the older cells up toward the surface. The
keratinocytes produce and fill themselves with keratin as they move toward the
surface. By the time they reach the stratum corneum, the keratinocytes have
completely filled with keratin and died. This process is called cornification.
These cells form a very durable stratum corneum at the surface.

base to the epidermis at an angle. When this muscle contracts, it pulls on the
hair follicle’s base, making the hair stand perpendicular to the skin’s
surface.

developing fetus?
1. A)
Lanugo
2. B)
Vellus
3. C)
Terminal
4. D)
Vellum
Answer: A
Explanation: Lanugo hair is very fine and unpigmented and
forms on a fetus during the last three months of its development. This hair is
usually replaced by birth. Vellus hair is also unpigmented and very fine,
replaces lanugo hair around the time of birth. An example of vellus hair is the
body hair on most women and children. Terminal hair is thick, coarse, and
heavily pigmented. It forms the eyebrows, eyelashes, and hair on the scalp. At
puberty, terminal hair forms in the axillary and pubic regions for both sexes.

1. A)
The shaft’s cross-sectional shape
2. B)
The length of the shaft
3. C)
The color of the hair shaft
4. D)
The amount of keratin in the hair shaft
Answer: A
Explanation: The hair texture depends on the shaft’s
cross-sectional shape. Straight hair has a round shaft, wavy hair has an oval
shaft, and curly hair has a more flat shaft. Rates of growth within the
follicle matter too. Straight hair grows evenly within the follicle. Wavy and
curly hair may grow alternately faster on one side of the follicle than on the
other.

60) Which of the following statements is not a description of
how skin protects the body?
1. A)
Cornified stratum corneum makes it hard for pathogens to enter.
2. B)
The skin’s surface has an acidic pH.
3. C)
The skin has dendritic cells that respond to pathogens.
4. D)
All of these are descriptions of how the skin protects the body.
Answer: D
Explanation: The dead, cornified stratum corneum of the
skin makes entry for bacteria difficult. The skin’s surface is also dry with an
acidic pH, making it an unfriendly place for bacteria to grow. Dendritic cells
of the epidermis stand guard if any pathogens try to make it past the stratum
corneum.
