Which Two Types of Tissue Have the Greatest Ability to Repair

Question

Which two types of tissue have the greatest ability to repair themselves?
A) epithelial and muscle
B) connective and muscle
C) epithelial and connective
D) muscle and nervous

Accepted Answer

Epithelial tissue, which forms the outer layer of our skin and lines our internal organs, has a high rate of turnover and self-renewal, allowing it to repair quickly. Connective tissue, which includes bone, cartilage, and blood vessels, also has a good ability to repair itself due to the presence of cells called fibroblasts that can produce new collagen and extracellular matrix. Muscle and nervous tissue have more limited abilities to repair themselves.
