Commissura is a Latin term that refers to a structure or a region where multiple parts of a body join together or form a connection. The word is derived from the Latin verb "committere" which means "to join together" or "to connect." Commissura is commonly used in anatomy and biology to describe the junction or union of different tissues, organs, or structures.
In human anatomy, commissura typically refers to the point at which nerve fibers cross from one side of the body to the other, allowing communication and coordination between the left and right sides of the body. The best-known example of this is the corpus callosum, which is a broad band of nerve fibers that connects the two cerebral hemispheres of the brain.
Commissura can also be used to describe the connection between other structures, such as blood vessels, muscles, or even plant parts. For instance, in botany, it refers to the point where two leaf margins or lobes meet. In entomology, commissura may describe the joining point of wing veins in insects.
The term commissura encompasses a wide range of connections or junctions across various disciplines. Its usage highlights the importance of interconnectedness and communication between different parts or systems in the body or other organisms.

The word "commissura" derives from the Latin noun "commissus", which is the past participle of the verb "committere", meaning to unite or to join together. "Committere" is composed of "com-" (meaning together) and "mittere" (meaning to send or to cause). The Latin noun "commissura" is formed by adding the suffix "-ura" to "commissus", which refers to the action or result of joining or uniting.
