Question 9

Which of the following is NOT a function of neurons?

Accepted Answer

Providing structural support

Question 10

Which layer of the epidermis contains melanocytes?

Accepted Answer

Stratum basale

Question 11

Which of the following glands are responsible for thermoregulation through sweat production?

Accepted Answer

Eccrine sweat glands

Question 12

Sebaceous and sweat glands are primarily located in which layer of the skin?

Accepted Answer

Dermis

Question 13

Which type of sweat gland becomes active during puberty and is associated with body odor?

Accepted Answer

Apocrine gland

Question 14

A patient presents with a lack of pigment in patches of skin. Which cell type is most likely malfunctioning?

Accepted Answer

Melanocytes

Question 15

Which equation best represents the relationship between surface area and rate of sweat evaporation from the skin?

Accepted Answer

$Rate = k 	imes Surface\ Area$

Question 16

If a person has a genetic mutation that reduces the number of eccrine sweat glands, what physiological effect would most likely occur during exercise?

Accepted Answer

Impaired thermoregulation and increased risk of overheating

Question 17

Which of the following best describes the role of the stratum basale in skin regeneration?

Accepted Answer

It contains stem cells that divide to produce new keratinocytes.

Question 18

A histological slide shows branched muscle fibers with striations and intercalated discs. Which tissue is this?

Accepted Answer

Cardiac muscle

Question 19

Which formula would you use to calculate the total number of nuclei in a sample of skeletal muscle fibers, given the number of fibers ($n$) and the average number of nuclei per fiber ($m$)?

Accepted Answer

$Total\ Nuclei = n 	imes m$

Question 20

Which of the following scenarios best illustrates the function of glial cells in the nervous system?

Accepted Answer

Glial cells insulate axons, speeding up nerve impulse transmission.
