Rib healing: No real good studies on rib fractures. They can hurt for weeks or longer depending on how bad the fractures are. Usually walking around is good.
Subcutaneous tissue. The subcutaneous tissue, also called the subcutis, hypodermis, hypoderm, subcutis, or superficial fascia, is the lowermost layer of the integumentary system in vertebrates.
Subcutaneous tissue is absent over the medial and lateral palpebral ligaments, where the skin adheres to the underlying fibrous tissue. Dermatochalasis, blepharochalasis, and epicanthic folds all are conditions that primarily involve the skin and subcutaneous tissue of the eyelids.
