Final answer:
The trigeminal ganglion is indeed a homologue of the dorsal root ganglion, performing a similar function for cranial nerves as the dorsal root ganglia do for spinal nerves.
Step-by-step explanation:
The statement regarding the trigeminal ganglion being a homologue of the dorsal root ganglion is true. The trigeminal ganglion is analogous to the dorsal root ganglia associated with spinal sensory nerves, as they both serve as collections of sensory neuron cell bodies. While the trigeminal ganglion is associated with a cranial nerve and found superficial to the temporal bone, its function is similar, conveying sensory information from the face to the brain. In contrast, the dorsal root ganglia are associated with the spinal nerves and convey sensory information from the body to the spinal cord.
