Compared to parasympathetic ganglia, sympathetic ganglia are:

• A. located closer to the spinal cord
• B. responsible for rest and digest functions
• C. composed entirely of sensory neurons
• D. embedded within target organs

Answer: (A)

Verified step by step guidance

1. Understand the difference between the parasympathetic and sympathetic divisions of the autonomic nervous system. The parasympathetic division is responsible for 'rest and digest' functions, while the sympathetic division is responsible for 'fight or flight' responses.
2. Recall the anatomical location of ganglia in both divisions. Parasympathetic ganglia are typically located near or within the target organs, whereas sympathetic ganglia are located closer to the spinal cord in structures called the sympathetic chain or paravertebral ganglia.
3. Eliminate incorrect options based on the functions and composition of the ganglia. For example, sympathetic ganglia are not composed entirely of sensory neurons; they contain motor neurons that control involuntary functions.
4. Focus on the correct anatomical placement of sympathetic ganglia. They are positioned closer to the spinal cord, which allows for rapid communication during 'fight or flight' responses.
5. Select the correct answer based on the anatomical and functional differences: sympathetic ganglia are located closer to the spinal cord.
