Flashcards in Synapes Deck (11):
1

How do neurotransmitters travel down the neuron axon?

Down the Microtubules

2

What do the vesicles contain at the synaptic knob?

Neurotransmitters

3

What is the main neurotransmitter?

Acetycholine

4

What are voltage gated channels?

They are a cell membrane ion channels which is activated by changes in electrical membrane potential near the channel.

5

What ion come in at the synaptic knob?

Calcium

6

What are the two different forms of action potential?

Excitatory & Inhibitory

7

Would it be cation or an anion would enter the cell to cause depolarisation?

Cation

8

What is a cation and a anion?

Cation is a positively charged ion and anion is a negatively charged ion

9

What is summation?

The name given when lots of axon terminals meet dendrites of another cell, rather than one terminal on one dendrite

10

What are the two different types of Summation?

Temporal Summation - where only 1 terminal ending sends a fast and rapid message.
Spatial Summation - where many impulses are sent from all the terminal ends.

11

What happens to excess neurotransmitter?

Re-uptake or enzyme breaks it down.
