hi, ana, well, i can try to ask. but i think, that if there are to be questions about ANS, it could be e.g. about those things mentioned in the class - distribution of the sympathetic and parasympathetic (are both present in the whole body?), their CNS origin (which cranial nerves contain parasympathetic portion, which part of spinal cord gives origin to sympathetic system and which to parasympathetic);
Matija also mentioned other differences between the two systems - where are located ganglia for these systems (e.g. intramural parasympathetic vs. truncus sympathicus along the vertebral column), which transmitters are employed in these systems;
it is good to know basic function of these systems (although you will learn more about it in physiology);
and it would be good to learn parasympathetic ganglia in the head region - 4 ganglia - their location, nerves involved ("bringing" signal to these ganglia (like oculomotor nerve for ciliary ganglion etc)), their relation to salivary glands innervation
