Verified step by step guidance

Understand the anatomy of the spinal cord: The spinal cord is a cylindrical structure that extends from the brainstem and is protected by the vertebral column. It contains gray matter and white matter, which are organized into specific regions.

Identify the major structures within the spinal cord: The spinal cord has regions such as the dorsal horn, ventral horn, lateral horn, and central canal. These structures are part of the gray matter and are involved in processing sensory and motor information.

Clarify the role of the dorsal horn: The dorsal horn is a major structure within the spinal cord. It is responsible for receiving and processing sensory information from the peripheral nervous system, such as pain, temperature, and touch.

Compare the options provided: The thalamus, cerebral cortex, and cerebellum are parts of the brain, not the spinal cord. The dorsal horn is the correct answer because it is a structure specifically found within the spinal cord.

Conclude the reasoning: Based on the anatomical location and function, the dorsal horn is the major structure within the spinal cord, while the other options are brain structures unrelated to the spinal cord.
