The Spinal Cord during the First and Early Second Trimesters 4- to 108-mm Crown-Rump Lengths

Book excerpt: This fourteenth of 15 short atlases reimagines the classic 5 volume Atlas of Human Central Nervous System Development. This volume presents sections of the spinal cord from specimens between 4 mm and 108 mm with detailed annotations. Extensive 3-D reconstructions show the early development of the germinal zones, the earliest neurons and early white matter accumulations at cervical levels only. Other 3-D reconstructions in older specimens show the progressive segregation of motor neuron columns at all levels in the ventral gray. The Glossary (available separately) gives definitions for all the terms used in this volume and all the others in the Atlas. Key Features Classic anatomical atlases Detailed labeling of the structures in the developing spinal cord offers updated terminology and the identification of unique developmental features, such as germinal matrices of specific neuronal populations and migratory streams of young neurons Appeals to neuroanatomists, developmental biologists, and clinical practitioners A valuable reference work on brain development that will be relevant for decades
