Which tissue injury is often associated with abrasions?

Abrasions are defined as superficial injuries to the surface of the skin, typically caused by friction or rubbing against a rough surface. They result in damage to the outer layers of skin, often characterized by redness, pain, and sometimes bleeding. Because abrasions involve the skin's outer layer, they are directly associated with skin damage.

In contrast, a bone fracture involves a break in the continuity of the bone, while a cartilage tear affects the flexible connective tissue that cushions joints, and a muscle strain pertains to overstretching or tearing of muscle fibers. None of these injuries are connected to abrasions in terms of the specific nature of their occurrence; abrasions are solely linked to skin damage resulting from external mechanical forces. Thus, recognizing that abrasions specifically cause skin injury emphasizes the role of the skin as the primary tissue affected.
