37. Four pairs of nuclei in the brainstem and the intermediolateral gray columns
at the S-2 through S-4 levels of the spinal cord are made up of the cell bodies of the
neurons. The intramural ganglia within the walls of the
___________________ organs are made up of the cell bodies of the p____________
neurons. As compared to that of the sympathetic NS, the parasympathetic
NS has the (same) (opposite) effect on visceral organs.

side of the body. The left half
of the brain controls the
side of the body.
44. A pyramidal pathway is primarily concerned with
control of body parts, particularly the
s. These pathways are
called pyramidal because their neuron processes help to make up structures in the base
of the brain called
