Verified step by step guidance

Understand the anatomy of spinal nerves: Spinal nerves are mixed nerves that emerge from the spinal cord and are formed by the union of dorsal and ventral roots. They divide into branches called rami, which include the dorsal ramus and ventral ramus.

Clarify the role of the ventral ramus: The ventral ramus is responsible for innervating the muscles and skin of the limbs and anterior trunk. It is directly associated with the rami of the spinal nerves.

Differentiate the dorsal root ganglion: The dorsal root ganglion contains sensory neuron cell bodies and is part of the dorsal root, not the rami. It is not directly associated with the rami of the spinal nerves.

Eliminate unrelated structures: The spinal cord gray matter is part of the central nervous system and is not directly associated with the rami. Similarly, the cerebral cortex is part of the brain and unrelated to spinal nerve rami.

Conclude that the ventral ramus is the correct answer: Based on the anatomy and function of spinal nerves, the ventral ramus is directly associated with the rami of the spinal nerves.
