autonomic ganglia contain ______.
synapses between postganglionic fibers and their effectors
an outer connective tissue capsule around the cell bodies of preganglionic motor neurons
the cell bodies of motor neurons
both somatic afferent and efferent neurons

Explanation:

To solve this, we analyze each option:

1. "Synapses between postganglionic fibers and their effectors" occur at effectors (e.g., organs), not in autonomic ganglia. Eliminate this.
2. Autonomic ganglia have cell bodies of postganglionic neurons, not preganglionic (preganglionic cell bodies are in CNS). The "outer connective tissue capsule" description is incorrect for preganglionic neuron cell bodies. Eliminate this.
3. Autonomic ganglia contain the cell bodies of postganglionic motor neurons (part of the autonomic motor pathway). This matches the structure of autonomic ganglia.
4. Autonomic ganglia are part of the autonomic (visceral) nervous system, not somatic. Somatic afferent/efferent are for voluntary/sensory to skeletal muscle, not in autonomic ganglia. Eliminate this.

Answer:

the cell bodies of motor neurons (the third option, with the text "the cell bodies of motor neurons")
