Organisation of the Sympathetic Nervous System

Noradrenaline vs Adrenaline

• Both are catecholamines and monoamine neurotransmitters

• adrenaline has an extra methyl on the amine group

where is choline acetyltransferase located

in the pre synaptic nerve terminal cytoplasm

where are niocotinic acetylcholine receptors located?

autonomic ganglia

both sympathetic and parasympathetic ganglia

is bronchoconstriction sympathetic or parasympathetic

parasympathetic

acetylcholine in parasympathetic or sympathetic

• mostly parasympathetic

• sympathetic in salivary glands

parasympathetic neurons length

• pre ganglionic neuron is long

• post ganglionic neuron is short

location of ganglia for sympathetic vs parasympathetic

• sympathetic - paravertebral

• parasympathetic - close to target

parasympathetic output

• medulla

• sacral region

sympathetic output

thoracic

lumbar

which acetylcholine receptor is found in the pns

• muscarinic, gpcr
