Explain why the dorsal root ganglions are larger in diameter than the dorsal root?
Dorsal root ganglia contain cell bodies of sensory neurons, which are larger and more complex structures compared to the dorsal root that mainly consists of nerve fibers. The ganglia need more space to accommodate the cell bodies and additional structures like satellite cells and glial cells, leading to their larger diameter compared to the dorsal root.
What neurotransmitter is used by most postganglionic sympathetic neurons?
