Answer 1

what part of the body has both a name and function, but in actuality isn't actually there?

the pupil!



it's just a hole in your eye to control the amount of light  that goes in the eye.

EDIT:

Here's another one for ya.

Why is the transmission of electrical impulses to your brain so efficient and quick even when receiving impulses from far away body parts?

The neuron is covered in myelin. The myelin insulates the neuron in the same way plastic over an electrical wire does. It contains the charge as well as ensures speedy delivery of information.

That is a best answer! :)
