Doctors often advise people suffering from the early stages of osteoporosis to spend more time outside. Why?
a. It’s stuffy inside and people sneeze more (in response to mildew and mold). As calcium is lost primarily through nasal mucus, going outside makes sense.
b. A form of Vitamin D circulates in dermal blood vessels and is activated by UV radiation to a compound that increases Ca2+ loss .
c. Melanin acts as a precursor for Vitamin D. Once exposed to sunlight, this melanin is broken down into calcitriol, which increases blood calcium levels.
d. A Vitamin D precursor is present in dermal vessels. Exposure to the sun converts this precursor molecule into a form of Vitamin D that can be further transformed into calcitriol.
e. none of the above |

Where does melanin come from?
a. Holocrine glands called melanocytes produce melanin. It gets passed from cell-to-cell via gap junctions by simple diffusion
b. Melanocytes, found in the top stratum of the epidermis, die and release melanin which then filters down to the deeper layers within the epidermis

d. Melanin, found in the basal layer of the epidermis, is produced by melanocytes. These melanocytes are distributed to keratinocytes via dendrites.
e. Melanosomes are produced by melanocytes and travel deep into the dermis to protect underlying structures via dendrites. |
