Common findings in heart failure are fluid retention by the kidneys and stimulation of the heart by the sympathetic nervous system. How would both of these findings help the body to compensate for the failing heart?

How does the emergence of sympathetic fibers from the spinal cord differ from the emergence of parasympathetic fibers?

The parasympathetic nervous system influences digestion bya. relaxing smooth muscle,b. stimulating peristalsis and secretory activity,c. constricting sphincters,d. none of these.

Explain both the anatomical and functional divisions of the nervous system. Include the subdivisions of each.

Tara, a 16-year-old girl, was rushed to the hospital after taking a bad spill off the parallel bars. After she had a complete neurological workup, her family was told that she would be permanently paralyzed from the waist down. During rehabilitation, her neurologist outlined for Tara and her parents the importance of preventing complications in such cases. Common complications include urinary infection, bed sores, and muscular spasms. Using your knowledge of neuroanatomy, explain the underlying reasons for these complications.

Describe the neural mechanisms responsible for controlling blood pressure.
