o ankle
o back
o jaw
o knee

question 222
herpes in greek means:
o to flow
o to creep
o to scab
o to scar

Explanation:

• Question 220: The optic nerve is where the ganglion cell axons exit the eye. It has no rods or cones, so it is the blind spot. The macula contains the fovea (high - acuity vision area with many cones), the retina has rods and cones (photoreceptors), and the fovea is a part of the retina with a high density of cones.
• Question 221: "Genu" is a Latin root that means knee. So "genu osteoporosis" is osteoporosis of the knee. The root for ankle is "talo -", for back is "lumb -" (related to lumbar region) or "dorsi -", and for jaw is "mandibulo -".
• Question 222: The Greek word "herpein" means "to creep". Herpes viruses are named so because the skin lesions (like in herpes simplex) can spread or seem to "creep" across the skin.

Answer:

• Question 220: optic nerve
• Question 221: knee
• Question 222: to creep
