The bones are primarily covered by a tough, thin membrane called the periosteum.
The periosteum serves as the outermost covering of bones, providing protection and support. Beneath this outer layer lies a complex network of tunnels and canals that house blood and lymphatic vessels, essential for nourishing the bone tissue. Furthermore, the periosteum acts as an attachment point for muscles, ligaments, and tendons, facilitating movement and stability. Here's a more detailed breakdown:
-
Periosteum: This is the primary membrane covering the bone. It's a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.
-
Function of the Periosteum:
- Protection: It shields the bone from external damage.
- Nourishment: Blood vessels within the periosteum supply nutrients to the bone.
- Attachment: It serves as an anchor point for muscles, tendons, and ligaments.
- Bone Growth and Repair: The periosteum contains cells that can form new bone tissue, aiding in growth and repair.
In summary, the periosteum is the key structure that covers and protects the bones, while also facilitating their nourishment and enabling the attachment of other tissues.
