List and define 4 anatomy terms from the question below. Jack is researching a mysterious genetic mutation. in this mutation, the innervation of the sympathetic and parasympathetic nervous systems are reversed. Predict 2 specific complications that you would see in this situation. Include a compasion and explination of the normal vs mutant antonomy ( structure and function) for each complication you predict. Use up to 4 sentences and be anatomically correct.

Xena eventually catches Callisto (remember, she is 25 years old). Salmoneus, who is 60 years old, agrees to deliver Callisto to face charges for war crimes. On the way, their cart crashes down a ravine. Salmoneus also suffers damage to his spinal cord during the accident. Compare the likely degree of regeneration/recovery of his spinal cord with that of the injured skeletal muscles and describe the consequences of your observations for his quality of life and ability to remain active.
