Textbook Question
Chapter 14, Problem 3TYC
Anthony gets into a fight between rival gangs. As an attacker comes at him with a knife, he turns to flee, but stumbles. The attacker stabs him on the medical side of the right gluteal fold, and Anthony collapses. He loses all use of his right limb, being unable to extend his hip, flex his knee, or move his foot. He never fully recovers these lost functions. Explain what nerve injury Anthony has most likely suffered.

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.
