At the post-ganglionic synapse

In the CNS

At the ganglion

At the pre-ganglionic synapse

In the pre-synaptic terminals

A Varicosity

An output terminal

A Terminal

A diffuse terminal

A Discrete synapse

Carry bidirectional information to and from the ganglia and target tissue

Carry information to target tissue in both Somatic and Autonomic Nervous Systems

Carry afferent information from the Autonomic ganglia to the CNS

Carry efferent information from the Autonomic ganglia to the target tissue

Carry bidirectional information to and from the CNS and the ganglia

Involves beta adrenergic receptors acting through the Adenylate cyclase / cAMP signalling pathway and alpha adrenergic receptors acting through or the PLC-beta pathway

Involves alpha or beta adrenergic receptors that act either through the Adenylate cyclase / cAMP signalling pathway or the PLC-beta pathway

Acts only through the Adenylate cyclase / cAMP signalling pathway

Involves alpha adrenergic receptors acting through the Adenylate cyclase / cAMP signalling pathway and beta adrenergic receptors acting through or the PLC-beta pathway

Acts only through the PLC-beta signalling pathway

The ANS has a two-neuron chain whereas the Somatic NS has a single neuron from CNS to effector tissue

The ANS uses class C neurons whereas the Somatic NS uses class A myelinated neurons for the output from the CNS

Both systems use class A myelinated neurons for the output from the CNS

The Somatic NS has a two-neuron chain whereas the ANS has a single neuron chain from CNS to effector tissue

The Somatic NS but not the ANS has ganglia between CNS and effector tissue

The ANS is only comprised of unmyelinated motor neurons therefore it is slower than motor neurons innervating skeletal muscle

Motor neurons in the ANS travel at the same speed as motor neurons innervating skeletal muscle

The ANS is comprised of type A motor neurons

The ANS is comprised of faster conduction speed Type B and C motor neurons

The ANS is comprised of slower speed Type B and C motor neurons

Is carried by pre-ganglionic neurons to the ganglion

Is carried by Dorsal Root Ganglion

Via the Vagus Nerve

Flows directly to the pre-ganglionic neuron

Flows directly to the hypothalamus
