- Draw the two neurons involved in a parasympathetic motor
response (preganglionic and post ganglionic) of the heart.
- The preganglionic neuron should come from the Vegus nerve (cranial nerve X) and be long.
- The postganglionic neuron should be much shorter and extend all the way to the heart (the ganglion is CLOSE to the heart).
- Indicate the neurotransmitter released from each neuron (both pre and post ganglionic) and the neurotransmitter receptor on BOTH of the post-synaptic cells.
