Crossing over, similar to an X.
The crossing of nerve fibres in the central nervous system.
Natural crossing over of fibers, especially nerve fibers, or other parts from opposite sides of the body, to form an X shape.
A point at which two or more structures of the body cross to the opposite side. The term is used particularly for the point at which nerve fibers cross over in the central nervous system.
Any point in the nervous system at which nerve fibres cross from one side to the other: for example, the decussation of the pyramidal tracts in the medulla, where the motor fibres from one side of the brain cross to the other side of the spinal cord.
A crossing of structures in the form of an X.
A crossover point where two or more structures within the body intersect and cross to the opposite side is known as a “decussation.” An illustration of this phenomenon is the point at which nerve fibers intertwine and cross paths in the central nervous system.
The transition from one side to the other, like the switching of nerve fibers in the brain or spinal cord.
