From your first comment, Debivort, you raise the issue of the synapse being connected to the soma, but this is not necessarily wrong, as presynaptic axons often synapse with postsynaptic neuron's body, creating an axosomatic synapse. Not all synapses are axodendritic synapses. See this image. There are some issues to clear up with the terms ...
The Edinger–Westphal nucleus refers to the adjacent population of non-preganglionic neurons that do not project to the ciliary ganglion, but rather project to the spinal cord, dorsal raphe nucleus, lateral septal nuclei, lateral hypothalamic area and the central nucleus of the amygdala, among other regions.

A motor neuron (or motoneuron or efferent neuron [1]) is a neuron whose cell body is located in the motor cortex, brainstem or the spinal cord, and whose axon (fiber) projects to the spinal cord or outside of the spinal cord to directly or indirectly control effector organs, mainly muscles and glands. [2]
The two main types of cells in the brain are neurons, also known as nerve cells, and glial cells, also known as neuroglia. [1] There are many types of neuron, and several types of glial cell. Neurons are the excitable cells of the brain that function by communicating with other neurons and interneurons (via synapses ), in neural circuits and ...
The red nucleus may play an additional role in controlling muscles of the shoulder and upper arm via projections of its magnocellular part. [ 6 ] [ 7 ] In humans, the red nucleus also has limited control over hands , as the rubrospinal tract is more involved in large muscle movement such as that for the arms (but not for the legs, as the tract ...
