elbow joint

Bends your arm

The elbow joint is where the upper arm bone meets the two forearm bones, allowing the arm to bend and straighten.

In plumbing, an elbow joint is a pipe fitting that creates an angled connection, typically at 90 or 45 degrees: We need an elbow joint to route the pipe around the corner.
