Answer to Question 1
The targets of the autonomic nervous system's motor neurons include the smooth muscle cells as well as the cardiac muscle (heart muscle) and pacemaker cells (the specialized heart cells that create the heart's rhythms and therefore regulate its pace of contraction).
Answer to Question 2
The limbic system was first proposed by James Papez in 1937 and later extended by Paul MacLean as the brain's neural circuit for emotion. The system includes interconnected phylogenically primitive nuclei and parts of the neocortex that form a circle (a border or limbus) around the inner core of the brain. These structures include the hippocampus, the thalamus, parts of the hypothalamus, the amygdala, the pre-frontal cortex, and other structures such as the cingulated gurus.
