RT Book, Section A1 Waxman, Stephen G. SR Print(0) ID 1171520399 T1 The Brain Stem and Cerebellum T2 Clinical Neuroanatomy, 29e YR 2020 FD 2020 PB McGraw-Hill Education PP New York, NY SN 9781260452358 LK neurology.mhmedical.com/content.aspx?aid=1171520399 RD 2024/04/19 AB The brain stem includes the medulla and pons, located ventral to the cerebellum. In addition to housing essential ascending and descending tracts, the brain stem contains nuclei that are essential for maintenance of life. As a result of the relatively tight packaging of numerous ascending and descending tracts, as well as nuclei, within the brain stem, even small lesions within it can injure multiple tracts and nuclei within it and thus can produce very significant neurologic deficits. It is therefore important for all clinicians to have a good understanding of brain stem anatomy.
