Verified step by step guidance

Understand the anatomy of the spinal cord: The spinal cord gray matter is divided into regions called horns—dorsal (posterior), ventral (anterior), and lateral horns. Each horn contains specific types of neurons associated with different functions.

Focus on the lateral horn: The lateral horn is present in the thoracic and upper lumbar regions of the spinal cord. It is specifically associated with autonomic functions, which control involuntary processes such as heart rate, digestion, and glandular activity.

Identify the type of neurons in the lateral horn: The lateral horn contains autonomic motor neurons. These neurons are part of the autonomic nervous system and are responsible for transmitting signals to smooth muscles, cardiac muscles, and glands.

Eliminate incorrect options: Somatic motor neurons are located in the ventral horn and control voluntary movements. Interneurons for pain reflexes are typically found in the dorsal horn, which processes sensory information. Somatic sensory neurons are also located in the dorsal horn and are involved in transmitting sensory signals.

Conclude the correct answer: Based on the anatomical location and function, the neurons located in the lateral horn of the spinal cord gray matter are autonomic motor neurons.
