Question 95

To solve this, we analyze each option:

• "pollex-" refers to the thumb (in anatomical terminology).
• "planto-" relates to the sole of the foot.
• "poples-" relates to the hamstring or the back of the knee.
• "hallux-" refers to the big toe.

So the correct term for the thumb's word part is "pollex-".

We recall the anatomy of the eye:

• The vitreous fluid is in the posterior chamber, behind the lens.
• The retina is at the back of the eye, behind the vitreous.
• The lens is located directly behind the pupil and iris, responsible for focusing light.
• The cornea is at the front of the eye, in front of the iris.

Thus, the structure behind the pupil and iris is the lens.
