What is a hindbrain and midbrain structure that connects to the spinal cord?

The medulla oblongata and pons are the two hindbrain and midbrain structures that are a part of the brainstem. The pons contains neural connections or tracts that help in information exchange between the cerebellum, thalamus and the cerebrum. The lower part of the medulla oblongata or medulla however connects to the spinal cord, as an extension of the brainstem. The medulla oblongata performs the function of regulation of respiration, breathing, heart rate and blood pressure.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
