Anatomical Diagram of Vertebrate Central Nervous System - Labeled Cross-Section #3007507 (License: Personal Use)

This historical-style anatomical drawing depicts a transverse section through the head and upper spinal region of a vertebrate, highlighting symmetrical brain hemispheres (labeled i), paired lateral ventricles (sy), a central cavity (h) likely representing the spinal canal or fourth ventricle, and surrounding meningeal layers. Key landmarks include the anterior commissure or optic chiasm area (a), dorsal midline structure (x), and peripheral nerve roots (r) emerging laterally, with a ventral structure labeled st possibly indicating the notochord or ventral nerve cord remnant. The image uses stippling and contour lines to convey tissue density and boundaries.

Used in educational anatomy resources, neuroscience textbooks, or museum exhibits to illustrate early 20th-century neuroanatomical understanding; serves users seeking foundational knowledge of CNS organization or historical scientific illustration techniques.
