COMMISSURE Meaning and
Definition
-
A commissure is a term used in anatomy to refer to a connection or joining point between two structures, typically found in the central nervous system. It is specifically used to describe a bundle of nerve fibers, axons, or tracts that cross from one side of the body to the other, allowing communication and coordination between different parts of the nervous system.
In the brain, commissures play a crucial role in interhemispheric communication. One of the most well-known examples is the corpus callosum, a large commissure that connects the left and right hemispheres of the brain. Through the corpus callosum, information is transmitted between the two hemispheres, facilitating bilateral integration and enhancing overall brain function.
Commissures are also found in other parts of the central nervous system, such as the spinal cord. The anterior and posterior commissures, for instance, are smaller bundles of nerve fibers that connect the two halves of the spinal cord, allowing for communication and coordination between the left and right sides of the body.
Overall, commissures are essential for the proper functioning of the nervous system and coordinating different parts of the body. By enabling the transmission of signals and information between various structures, they contribute to the overall integration and synchronization of the nervous system.
