Receptors for transmission only between neurons

Receptors for transmission at the ganglion

The receptors used by B class neurons in the ANS

G protein-coupled receptors

B class motor neurons, discrete synapses and post-synaptic GPCRs

Pre-synaptic facilitation and inhibition, post-tetanic potentiation and post-synaptic ionotropic receptors

B class motor neurons, discrete synapses and post-synaptic ion channel receptors

A alpha motor neurons, diffuse synapses and ionoropic post-synaptic receptors

Calmodulin

PLC-beta 1

Adenylyl cyclase

Chaperone protein

cAMP

Is the same as that used by non-steroid hormones

Like that used by non-steroid hormones, is located in the nuclear membrane

Like that used by non-steroid hormones, has receptors free floating within the cell

Shows crosstalk and binds non-steroid hormones

Is different from that used by non-steroid hormones

Blockage of post ganglionic transmission to target tissue in the sympathetic arm only of the ANS

No effect this compound would only cause paralysis of skeletal muscle because nicotinic receptors are found in the neuromuscular junction

 Blockage of post ganglionic transmission to target tissue in the parasympathetic arm only of the ANS

Blockage of transmission from preganglionic neurons fibers to post ganglionic fibers in the sympathetic arm of the ANS only

Blockage of transmission from preganglionic neurons fibers to post ganglionic fibers in both the sympathetic and parasympathetic arms of the ANS
