parasympathetic nervous systems.
AXON – A fibre-like extension of a neurone which allows transfer of information to
target cells Away from axon hillock*.
AXON HILLOCK – The region of the neuronal cell body where the axon emerges
and where the action potential is generated as a net effect of the integration of
neuronal stimulation and inhibition.
AXON TERMINAL – Nerve ending which forms presynaptic element of the neurone
where synaptic vesicles* are accumulated.
BASAL GANGLIA – Subcortical clusters of neurones, which include the following
nuclei: caudate, putamen, globus pallidus and substantia nigra. They play a role in
movement control.
BLOOD-BRAIN BARRIER – A barrier made of epithelial cells which line the blood
vessels of the brain. These cells form very tight junctions and control the passage of
