In conclusion, these results provide evidence for a functional subdivision between the pupillary and accommodation related preganglionic motoneurons.
This study also provides evidence for a functional subdivision of this preganglionic population.
Thus, the cat intraocular muscle preganglionic innervation is spatially organized with respect to function, despite the dispersed nature of its distribution.
Organization of the extraocular and preganglionic motoneurons supplying the orbit in the lesser galago.
This functional subdivision in the cat preganglionic distribution should have connectional and physiological consequences.
In the present study, injections of the anterior chamber were used to label the postganglionic and preganglionic afferents to the iris sphincter pupillae muscle.
Thus, these cases provide a picture of the overall preganglionic cell distribution, as demonstrated by a technique different from those previously employed.
The quantitative description of this distribution demonstrated that, despite an apparently diffuse organization, the location of preganglionic motoneurons in the cat is highly stereotypic.
