1. John has sustained a severe injury during football practice and is told that he has a torn knee cartilage. Can he expect a quick, uneventful recovery? Explain your response.
Answer: It will be a slow recovery because the healing process for cartilage is slower because cartilage tissue takes longer to heal.
Critical Thinking Questions
2. The epidermis (epithelium of the cutaneous membrane or skin) is a keratinized stratified squamous epithelium. Explain why that epithelium is much better suited for protecting the body's external surface than a mucosa consisting of a simple columnar epithelium would be.
Answer: The reason why keratinized stratified squamous epithelium is the better choice for protection is because the outer layer's cells contains keratin, which is a tough protective surface. This would be a strong protective surface.
