Bios252 week 3 lab - Study guides, Class notes & Summaries

Learning Objectives: ● Locate and identify the regions and parts of the spinalcord. ● Identify the spinal contributions to cervical, brachial, lumbar, sacral andcoccygeal plexuses. ● Locate and identify major peripheralnerves. ● Identify the components of a reflexarc. Introduction: The spinal cord is a continuation from the medulla oblongata of the brain stem. It allows communication between the brain and the rest of the body. The spinal nerves contain both sensory and motor fibers....
