LECOM-SH OPP 1001 – Osteopathic Principles and Practices Exam 1 Practice Test

In this model, body functions are governed by the nervous system, which includes three parts: the central nervous system (brain and spinal cord) processes information and issues commands; the peripheral nervous system (all the nerves outside the CNS) carries signals to and from the CNS; and the autonomic nervous system, a subset of the PNS, regulates involuntary activities like heart rate, digestion, and respiration to maintain balance. Together, these components describe how the nervous system controls most body functions, from movement and sensation to automatic regulatory processes. The other options list systems that influence function but are not described as the primary controllers in this neurological framework.
