Hypothalamospinal tract
Encyclopedia
The hypothalamospinal tract connects the thalamus
to the ciliospinal center
of the intermediolateral cell column in the spinal cord (T1, T2). It is found in the dorsolateral quadrant of the lateral funiculus
, in the lateral tegmentum
of the medulla
, pons
and midbrain. Lesions of the hypothalamospinal tract cause ipsilateral Horner's syndrome

Thalamus
The thalamus is a midline paired symmetrical structure within the brains of vertebrates, including humans. It is situated between the cerebral cortex and midbrain, both in terms of location and neurological connections...

Ciliospinal center
The ciliospinal center is a structure which receives input from the pretectum, and has output to the superior cervical ganglion.It is located in the intermediolateral cell columns of the spinal cord between C8 and T2....

Lateral funiculus
The most lateral of the bundles of the anterior nerve roots is generally taken as a dividing line that separates the antero-lateral region into two parts, viz., an anterior funiculus, between the anterior median fissure and the most lateral of the anterior nerve roots; and a lateral funiculus,...

Tegmentum
The tegmentum is a general area within the brainstem. It is located between the ventricular system and distinctive basal or ventral structures at each level...
of the medulla
Medulla
Medulla refers to the middle of something and derives from the Latin word for marrow. Its anatomical uses include:* Medulla oblongata, a part of the brain stem* Renal medulla, a part of the kidney* Adrenal medulla, a part of the adrenal gland...

Pons
The pons is a structure located on the brain stem, named after the Latin word for "bridge" or the 16th-century Italian anatomist and surgeon Costanzo Varolio . It is superior to the medulla oblongata, inferior to the midbrain, and ventral to the cerebellum. In humans and other bipeds this means it...

Horner's syndrome
Horner's syndrome is the combination of drooping of the eyelid and constriction of the pupil , sometimes accompanied by decreased sweating of the face on the same side; redness of the conjunctiva of the eye is often also present...
