Study Notes
Autonomic Nervous System
- The autonomic nervous system regulates functions that are not under voluntary control, such as cardiac muscle contractions and smooth muscle contractions.
Origin of Sympathetic Nerve Fibers
- Sympathetic nerve fibers originate from the thoracic and lumbar regions of the central nervous system (CNS).
Divisions of Autonomic Nervous System
- The sympathetic division is responsible for accommodation to stressful conditions.
- The parasympathetic division is responsible for maintaining normal physiology.
Efferent Nerve Fibers
- Efferent nerve fibers of the autonomic nervous system are referred to as preganglionic fibers.
