The ANS does not regulate (a) skeletal muscles, (b) cardiac muscles, (c) the digestive tract, (d) the bladder.
The ANS is subdivided into sympathetic and parasympathetic divisions. Review the differences between these two divisions by filling in the table below:

Which of the following is the best way to describe how the ANS is controlled? (a) completely under control of voluntary cerebral cortex, (b) entirely controls itself, (c) completely under control of brain stem, (d) little control by cerebrum, major control by hypothalamus and amygdaloid body, and major control by spinal and peripheral reflexes.
