More biology homework help, please!

[frogs]

Okay, now I'm really regretting not paying more attention in 4th year biology -- Mrs Thomas, if you're still out there, I'm sorry...

Dd1 has been given some questions that include the following task: Here is a diagram of a nerve cell. Make a drawing of two nerve cells attached to each other.

She insists they weren't told the answer to this, and has left her textbook at school so can't look it up. All the stuff on Google is far too specialised. Please help, it's due in tomorrow!

Ok, not easy to do, without a picture

have a shufti at this page, and scroll down a bit
to the bit on synapses....these are the junctions between two neurones btw

faculty.washington.edu/chudler/synapse.html

It is a fab site btw, and I'm sure your dd would love to make some of the moels of neurones etc

Shall I tell you my hourly tutorial rate

O---{ }---O--{

is the best I can do in ASCII!

neurone structure

Oooh, this takes me back. I luuuuurve biology!!

No pic of a synapse here though

Thanks, am just printing that off -- should do the trick nicely! I'm guessing the point being made is that the axon needs to join the dendrite rather than the axons joining each other.

The only kind of neural connections I know about are the AI kind...

Oh and if it will entertain her, the ends of the dendrites are sometimes called synaptic boutons, but are also accuratly called synaptic knobs!

here is a synapse

It's just where 2 nerves meet - there is a small gap across which the neurotransmitter travels. So just draw 2 nerves as in the first link but right next to each other with a small gap between. Like MB did!!

Axons go away fronm the cell body.. Dendrites go towards the cell body.

If she wasn't the uber smart kid effect tell her to use her arm and hand.

The hand is the cell body, the digits are the dendrites (d and D) and the arm is tha axon (a and a)

Cool and a model you can take into the exam with you!!!
