Neurological Foundations — Questions

Match each autonomic neuron segment to its connection.

Which central outflow pattern characterizes the sympathetic division?

• Thoracolumbar
• Brainstem only
• Craniosacral
• Sacral spinal only

Brainstem and sacral parasympathetic origins together form the _____ outflow.

Which pairing describes ordinary autonomic preganglionic transmission?

• Acetylcholine to neuronal nicotinic receptors
• Glutamate to ionotropic glutamate receptors
• Norepinephrine to adrenergic receptors
• Acetylcholine to muscarinic receptors

Select all correct features of ordinary autonomic cholinergic signaling.

• Parasympathetic postganglionic fibers usually release acetylcholine onto muscarinic targets
• Sympathetic preganglionic fibers release acetylcholine
• Every ordinary autonomic preganglionic synapse uses norepinephrine and adrenergic receptors
• Parasympathetic preganglionic fibers act on neuronal nicotinic ganglionic receptors
