Class 10: Autonomic Nervous System – Learning Objectives1. Compare and contrast theautonomic and somaticdivisionsof the peripheral nervous system, considering the type oftargets, neurotransmitters, and general functions with whichthey are involved.2. Compare and contrast thesympatheticandparasympatheticbranches of the autonomic nervous systembased on:neurotransmitters and receptors at theganglionicandtarget organsynapse, and general functional effects onthe target organs.3. Understand the interplay betweenparasympatheticandsympatheticinnervation of atarget organand when one ismore likely to be active than the other.
