13 Neuronal Communication Flashcards
1
Q
What are neurotransmitters?
A
Chemicals which are used to pass signals from one neurone to the next.
2
Q
What is a synapse?
A
Junction between two neurones (or neurone and effector)
3
Q
What is a presynaptic neurone?
A
Neurone along which the impulse has arrived.
4
Q
What is a postsynaptic neurone?
A
Neurone that receives the neurotransmitter.
5
Q
What is synaptic divergence?
A
When one neurone connects to many neurones and so information can be dispersed to different parts of the body.
6
Q
What is synaptic convergence?
A
When many neurones connect to one neurone and so information can be amplified.
