Final answer:
Ligaments and tendons are both dense connective tissues made up of collagen fibers. Under a microscope, ligaments have collagen and elastin fibers arranged in a wavy pattern, while tendons have collagen fibers lined up in a parallel arrangement.
Step-by-step explanation:
Ligaments and tendons are both types of dense connective tissue made up of collagen fibers.
Under a microscope, ligaments and tendons have different structures. Ligaments have collagen and elastin fibers arranged in a wavy pattern, allowing them to be stretched and return to their original shape. Tendons, on the other hand, have collagen fibers lined up in a parallel arrangement, giving them greater tensile strength. Ligaments and tendons are both dense connective tissues made up of collagen fibers. Under a microscope, ligaments have collagen and elastin fibers arranged in a wavy pattern, while tendons have collagen fibers lined up in a parallel arrangement.
