In botany, the reproductive parts of flowering plants are enclosed in a structure called a carpel. The area where one carpel meets another is a commissure. âCommissureâ is a word for a union such as a seam or joint.

In anatomy, commissure refers to a junction in heart valves, the fibrous connection of the brainâs left and right halves or nerve fibers that transverse the spinal cord.
