Axonal transmission

Question 1

2 types on connections between neurons?

Answer 1

1) axonal transmission = info from location A to B
2) synaptic transmission = integration/ processing of info
(failure in axonal = MS)

Question 2

Post synaptic potentials - 2 types?

passive conduction

Answer 2

EPSP (temporal) - excitatory
IPSP (spatial) - inhibitory
Voltage changes spread away from point of origin = passive conduction (reaches axon hillock = AP)

Question 3

Glial Cells

how many?

Answer 3

surround neurons and provide support and insulation

10-50 x no, of neurons

Question 4

Initiation and propagation of the action potential

Answer 4

receptors on dendritic tree and cell body activated
decremental conduction to axon hillock
depolarisation
AP moves down axon
