And here's your shmoop du jour brought to you by neurons, out of all
- 00:07
the cells in your body these have the most nerve... A long and skinny part of [A neuron]
- 00:12
a neuron extending from the cell body to the terminal buttons is called the what
- 00:16
and here are potential interesting....okay well here's a trick for remembering the [Magician on stage with a bunny in a hat]
- 00:22
shape of each part of the neuron their names sound a bit like what they look

like take A) the soma otherwise known as the cell body well this is a bulbous [soma diagram]
- 00:33
end of a neuron containing the cell body what does the soma look like a big round
- 00:37
body what else has a big round body a sumo..soma, sumo makes sense, definitely [A soma and sumo side by side]
- 00:44
not long skinny though let's take a look at C) dendrite, a dendrite is a system of
- 00:49
short branches that extend off the nerve cell to receive information from [A dendrite branch]
- 00:54
other neurons, well a dendrite looks branch like extending off the body and
- 00:58
curling about well what else curls? A plants tendril, dendrite..tendril..
- 01:05
useful to remember but not quite long straight skinny the synapse is a
- 01:10
tricky one its the structure that allows signals to travel between one neuron and [signals travelling between synapses]
- 01:14
another here's a diagram well none of that looks long and skinny so we can
- 01:18
definitely move on without even worrying about finding a word you can remember it by
- 01:21
because well nothing really works for synapse anyway or maybe something does [baby sleeping]
- 01:25
but we're 20 minutes past our coffee break and aren't capable of
- 01:28
thinking too hard about it all right the myelin sheath is pretty much what it [woman walking like a zombie for coffee]
- 01:32
sounds like a sheath. Thank You scientist for using a name that makes sense. Picture
- 01:37
a swords sheath, myelin sheath looks about the same and also happens to look long [myelin sheath with a swords sheath]
- 01:44
and skinny could this be our answer not quite anyway because as with the sword
- 01:50
and it's sheath, the myelin sheath is simply there to protect something far
- 01:55
more important inside which would be the axon, the axon is critical to
- 02:01
transferring messages from one neuron to the next as it takes the information [information transferring from neurons]
- 02:04
from the cell body to the terminal buttons to be carried away and also its
- 02:08
long and skinny so yeah it's our answer I think of the axon as the mule in a [Donkey crossing a road]
- 02:12
shady business transaction it's only job is to get the goods to the pickup location no
- 02:17
questions asked and no the axon doesn't look like a mule we kind of dropped
- 02:21
the whole looks like half way through this video sorry hey someone get [Woman begging for coffee]
- 02:24
us some coffee, stat!
