It is generally accepted that preganglionic neurons of the cervical sympathetic nerve arise from the ciliospinal center, which exists in the spinal cord over C8-T3. However, its distribution within the spinal cord has not been exactly demonstrated. Therefore, horseradish peroxidase (HRP) was injected into the cervical sympathetic trunk in order to demonstrate the distribution of preganglionic neurons in the spinal cord in the cat. Four adult cats were used. HRP was injected into the superior cervical sympathetic trunk. Two or three days after the injection cats were sacrificed and prepared for histochemical demonstration of HRP. The superior cervical ganglion, sympathetic trunk and spinal cord were examined. Labelled cells with HRP were found in the intermediolateral nucleus over C8-T6 on the ipsilateral side of the injection. These neurons were identified as preganglionic neurons of the cervical sympathetic nerve. In addition, a large number of labelled cells were seen at the T2 and T3 levels, but a few labelled cells were observed at C8, T5 and T6. T1 and T4 showed the moderate distribution. Preganglionic neurons in the ciliospinal center were located at the level from C8 to T6 of the spinal cord.

D009333	Neck	The part of a human or animal body connecting the HEAD to the rest of the body.	Necks
D009474	Neurons	The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.	Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D005728	Ganglia, Sympathetic	Ganglia of the sympathetic nervous system including the paravertebral and the prevertebral ganglia. Among these are the sympathetic chain ganglia, the superior, middle, and inferior cervical ganglia, and the aorticorenal, celiac, and stellate ganglia.

D006735	Horseradish Peroxidase	An enzyme isolated from horseradish which is able to act as an antigen. It is frequently used as a histochemical tracer for light and electron microscopy. Its antigenicity has permitted its use as a combined antigen and marker in experimental immunology.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
