1. Meibomian gland - sebaceous gland in eyelid to prevent eye tear film evaporation
Glands of moll - apocrine in eyelid, secretes lipid to prevent eye tear film evaporation
Areolar gland - sebaceous gland on areola for nipple lubrication
2. Collect cells in cervix, look under microscope for pre-cancerous (cervical intraepithelial neoplasia) associated with HPV.
3. Malleoli on fibula and tibia. Searched it up. Best guess - tibial plafond
Bonus. Type 6 and 11

Mhm! I'm sure you know this but for people looking at the marathon, other glands you could have mentioned are glands of Zeis, Fordyce spots, or some other fun ones like tyson's and montgomery glands. I was looking for the ankle mortise for the third one. Nice with the HPV types. Did you get that off the top of your head? Go ahead and ask one (or a few).

Haha, no. Off the cheat sheet. I was almost there with tibial plafond

Questions
1. Difference between tremor, spasm, tic, myoclonus
2. What is the difference between cross sectional area and physiological cross sectional area?
3. What's another name for infant botulism (2 possibilities)?

1. Tremor- rhythmic involuntary muscle contractions usually involving some type of oscillatory movement. Tic- habitual, involuntary spams usually in the facial muscles. Spasm- any sudden involuntary muscle convulsion. Myoclonus- sudden twitch of muscle(s) i.e. seizures.
2. PCSA is the area of a cross section taken perpendicular to muscle fibers, as opposed to CSA which is the area of a cross section taken perpendicular to the long axis of a muscle (or really whatever axis you want).
3. Floppy baby syndrome... not sure about a second.

All right. The second possibility is hypotonia.

Cool cool. Didn't know about hypotonia, thanks!

1. Briefly describe hormonal stimulation and inhibition of osteoclast activity. What receptors and hormones are involved and where are they located/produced?
2. What is the chemical precursor of Vitamin D that is actually activated by UV rays?

1. Osteoclasts are stimulated by a variety of hormones and chemicals, but some major ones are calcitonin, PTH, and IL-6. Since calcitonin increases the amount of calcium in the blood, it stimulates osteoclasts to remove bone. On the other hand, PTH (parathyroid hormone) inhibits osteoclast activity. Calcitonin is produced by the C-cells of the thyroid gland, and PTH is produced by the parathyroid gland. IL-6 is secreted by osteoblasts to inhibit osteoclast formation. 
2. 7-DHC

Hey guys, starting it off for 2017 what hairs in the ear convert sound waves into electrical signals?

[mangothecat]

Not sure if this is what you're looking for but... (Click to Show Hidden Text)

Inner hair cells in cochlea (which are made of a single kinocilium surrounded by multiple stereocilia)

[kajay0808]

yup thats right!
Your turn!

Name at least 2 second messenger systems water soluble hormones use to communicate with their target cells.
