Neurons in the cuneate nucleus of the camel brain stem were studied by Golgi method. Six types of neurons were identified based on soma size and shape, density of dendritic trees, morphology and distribution of spines, and appendages. Type I neurons had large spherical somata with somatic appendages. Dendritic appendages were predominant on proximal dendrites with terminal flower-like appendages. Type II neurons had medium to large soma. Appendages and spines were found for the soma as well as along dendrites of different orders. Axons with local branches were seen for these neurons. Type III neurons were small to medium spheroidal or triangulated with large number of spines and appendages on all parts of neurons including soma, dendrites, and initial axonal segments. Axons of these neurons branch profusely and formed rich local axonal arborizations. Type IV medium-size neurons have bipolar, round, or fusiform soma with somatic spines. Their dendrites were sparsely branching with spines and terminal side branches. Type V neurons were spheroid or triangular with small soma with somatic appendages. Their dendrites were sparsely branching and terminate as thin spiny side branches. Type VI neurons were small-size unipolar, round, or fusiform with some dendritic spines and protrusions. These findings shed some light on the structure of the cuneate nucleus of one of the largest animals (the camel). Anat Rec, 2012. © 2012 Wiley Periodicals, Inc.
