Glia
non-neuronal. Support and protection. Forms myelin
Neurons
Within cell communication- electrical eg action potential
Between shell communication- chemical eg NT
Neuronal circuits
Neurons connect to each other.
2 inhibitory + 1 excitatory = no action potential. Vice versa. But this depends on location on dendrite
Synapse
Chemical messengers (NT) released here.
Pre-synaptic terminal where NTs are released into synaptic cleft
Receptor molecules in post synaptic density. NTs bind here
EPSP
Make neuron more likely to fire AP.
Excitatory
Action potential
Typically runs from cell body along an axon to synapse
Neurotransmitters
Chemical messengers. From one neuron to the next at synapse level
Local action. Can be excitatory or inhibitory
Eg noradrenaline, dopamine, serotonin, acetylcholine, and GABA
Hormones
In blood
Testosterone, cortisol, adrenaline, noradrenaline
