labrum
Joint socket rim
Labrum is a technical term in anatomy and zoology for a lip-shaped structure or edge.
In human anatomy, it most commonly refers to the ring of cartilage surrounding the socket of the shoulder or hip joint, which deepens the socket and helps stabilize it.
She tore her labrum playing softball and needed surgery.
In entomology, the labrum is the upper lip of an insect's mouthparts, forming a flap that covers the mandibles.
