ciliospinal

The ciliospinal center is located between the C8 and T1 regions of the spinal cord within the intermediolateral column.

The enhanced ciliospinal reflex in asymptomatic patients with cluster headache is due to preganglionic sympathetic mechanisms.

The SCG receives input from the ciliospinal center.

The hypothalamospinal tract connects the thalamus to the ciliospinal center of the intermediolateral cell column in the spinal cord (T1, T2).

The ciliospinal center (in Latin: centrum ciliospinale) is a structure which receives input from the pretectum, and has output to the superior cervical ganglion.

The ciliospinal reflex (pupillary-skin reflex) consists of dilation of the ipsilateral pupil in response to pain applied to the neck, face, and upper trunk.

The preganglionic fibers that innervate the SCG are the thoracic spinal nerves, which extend from the T1-T8 region of the ciliospinal center .
