15 Brainstem Summary

The previous four chapters presented various aspects of the brainstem and its cranial nerves bit by bit. This chapter summarizes the major points, using as a vehicle the same series of drawings of brainstem sections used in Chapter 11, but with additional structures and brief descriptions added. A few of the structures (e.g., substantia nigra) are dealt with more fully in later chapters.

Important brainstem structures caudal to this level (i.e., between here and the spinal cord): pyramidal decussation (at the spinomedullary junction), where most fibers of the pyramids cross to form the lateral corticospinal tracts.

Rostral Medulla
