This anatomy tutorial covers the neurovasculature of the dorsal trunk and neck, focusing on the arteries, veins, and nerves in these regions. It begins with an overview of the occipital, vertebral, transverse cervical, posterior intercostal, subcostal, and lumbar arteries, detailing their origins and areas they supply. The tutorial then discusses the corresponding veins, including the occipital, deep cervical, posterior intercostal, subcostal, and lumbar veins, explaining their drainage paths. Finally, it explores the nerves in the area, such as the greater and lesser occipital nerves, suboccipital nerve, supraclavicular nerves, intercostal nerves, and lateral cutaneous branches, highlighting their functions and innervation areas.
