The C8-T2 region of the spinal cord is known as the Ciliospinal center of Budge.

• A. Ciliospinal center of Budge
• B. Intermediolateral cell column
• C. Lateral horn
• D. Dorsal horn

Answer: (A)

The main idea is that the C8–T2 spinal cord segments contain a specific cluster of preganglionic sympathetic neurons known as the Ciliospinal center of Budge. This center is the origin of sympathetic fibers that descend to the superior cervical ganglion to innervate head and neck structures, including pathways involved in pupil dilation. That precise eponym identifies the location and functional role of these preganglionic cells at those levels, which is why it’s the best answer.

The terms Intermediolateral cell column and lateral horn describe the general region where sympathetic preganglionic neurons reside, but the question targets the particular named center for those segments. The dorsal horn, by contrast, is the sensory/ interneuron region and does not contain the preganglionic sympathetic neurons relevant here.
