Lecture 7 - Brainstem I - organization, key landmarks and cross sections Announcements : Exam grading should be complete by Monday. Assignment : In Nolte read Chapter 11: “Organization of the brainstem”. For next lecture : Read Nolte Chapter 12: “Cranial nerves and their nuclei”. Lecture Outline : Brainstem - overview of important functions Brainstem - orientation and major subdivisions Brainstem surface anatomy Brainstem internal anatomy Introduction to brainstem cross sections Principal pathways are major components of the brainstem Review of principal pathways

Transverse planes (cross sections) defining the subdivisions of the brainstem. This is the key for the brainstem cross sections. Note that each third of the brainstem is subdivided, making a total of 6 primary brainstem sections. (there is an extra section to show the junction between the SC and caudal medulla).

Cross sections through the rostral medulla (A), rostral pons (B), and rostral midbrain (C) revealing major longitudinal subdivisions. These are, from dorsal to ventral, the 1) tectum, or roof, the area posterior to the ventricular space, most developed in the midbrain; the 2) tegmentum (Latin for “covering”); and 3) large structures “appended” to the anterior surface of the tegmentum.
