The Ciliospinal center of Budge is associated with which order of sympathetics?

Explanation:
The Ciliospinal center of Budge houses the preganglionic sympathetic neurons located in the intermediolateral cell column of the upper thoracic spinal cord (roughly T1–T2, sometimes cited C8–T2). These neurons are the second-order neurons in the sympathetic pathway to the eye. First-order neurons originate in the hypothalamus and descend to this spinal level to synapse here; from the Ciliospinal center, the second-order cells send axons to the superior cervical ganglion, where they synapse with the third-order postganglionic neurons that travel to the ocular targets like the dilator pupillae. So the Ciliospinal center of Budge is associated with the second-order sympathetic neurons.
