Book IV: The Trunk

Home

---

Book IV focuses primarily on the trunk. It presents the musculature both as separate abdominal and back musculature, as well as a combined spiral musculature.  The organization of the nervous system is covered, including dermatomes and the nerve plexuses. This is set in the context of movement, physical development, and respiration.
