Periosteum - English Definition & Meaning

Definition

The periosteum is a tough, fibrous membrane that covers the outer surface of bones. It plays a crucial role in bone growth, repair, and nutrition. This membrane contains blood vessels and nerves that supply the bone with essential nutrients and sensory information. The periosteum is responsible for forming new bone tissue during growth and fracture healing. Think of it as the bone's life support system, keeping it strong and healthy. It's essential for bone integrity and regeneration.

Etymology

The word 'periosteum' comes from the Greek words 'peri' (meaning 'around' or 'surrounding') and 'osteon' (meaning 'bone'). Thus, 'periosteum' literally means 'around the bone.' The term accurately describes its function as the outer covering of bones. It's been used in anatomical contexts for a long time.
