Ultrastructure of Human Cells

[shezomb]

Hi there!

I have an assignment due next week in which I have to explain the various organelles and their purpose in specific human cells (I have to choose 4 specialized cells). I was hoping for some help in finding some good example images that I can reference and explain? I've been trying to find some images or graphics of cells where the organelles are visible enough for me to explain them, but alas my googlefuu has proven too weak
I was hoping to look at some nerve cells, but we really haven't learnt much about different ones yet, so I'm just guessing what I'm trying to find out :s

Is this something you could help me with?

Many thanks for taking the time to look at my post
