Multiple Choice

Verified step by step guidance

Step 1: Understand the role of sympathetic postganglionic neurons in the autonomic nervous system. These neurons are part of the sympathetic division of the autonomic nervous system, which is responsible for the 'fight or flight' response.

Step 2: Recall the structural characteristics of sympathetic postganglionic neurons. These neurons are typically unmyelinated, which allows for slower conduction compared to myelinated neurons.

Step 3: Review the neurotransmitter released by sympathetic postganglionic neurons. They typically release norepinephrine, which acts on adrenergic receptors in target tissues.

Step 4: Identify the target organs innervated by sympathetic postganglionic neurons. These neurons innervate various organs, including the heart, blood vessels, and other tissues, to regulate functions such as heart rate and blood pressure.

Step 5: Locate the cell bodies of sympathetic postganglionic neurons. Their cell bodies are found in autonomic ganglia, which are clusters of nerve cells located outside the central nervous system.
