Verified step by step guidance

Understand the role of the dorsal root: The dorsal root is part of the spinal nerve and is responsible for transmitting sensory information from the peripheral nervous system (body) to the central nervous system (spinal cord). It contains sensory neurons that carry signals such as touch, pain, and temperature.

Differentiate between the dorsal root and ventral root: The ventral root primarily carries motor information from the spinal cord to the muscles, while the dorsal root carries sensory information to the spinal cord. This distinction is key to answering the question.

Eliminate incorrect options: The central canal is a cerebrospinal fluid-filled space in the spinal cord and does not transmit sensory information. The anterior median fissure is a groove on the spinal cord's surface and is not involved in sensory transmission. The ventral root carries motor signals, not sensory signals.

Focus on the correct structure: The dorsal root contains sensory neurons that transmit information from the body to the spinal cord. This aligns with the question's requirement for a structure responsible for sensory transmission.

Conclude based on anatomy: Based on the function and location of the dorsal root, it is the correct answer to the question. Sensory information travels through the dorsal root to reach the spinal cord for processing.
