1

What do Dendites do?

Recieve inputs from other neurones and convey graded electrical signals passively to the soma

2

What does the soma of a neurone do?

Synthetic and metabolic centre

 

It contains the nucleus, ribosome, mitochondria and endoplasmic reticulum

3

What does the Axon hillock and the Initial Segment do?

Site of initiation of the "all or none" action potential

4

What does the axon of a neuron do?

Conducts output signals as action potentials to other neurones

5

What does the synapse of a neurone do?

Point of chemical communication between neurones

6

What type or neurone is this?

Unipolar

 

Peripheral autonoic neurone

7

What type of neurone is this?

Pseudounipolar

 

Dorsal Root Ganglion Neurone

8

What type of neurone is this?

Bipolar

 

Retinal Bipolar Neurone

9

What type of neurone is this?

Multipolar

 

Lower motor neurone

10

What are the four funcitonal regions of a neurone?

Input

Integrative

Conductile

Output

11

How are synapses classified

Morphologically by the location of the presynaptic terminal upon the postsynaptic cell

12

What are the two classes of function for synapses?

Either

Excitatory

or

Inhibitory
