- These nerves are categorized into cervical, thoracic, lumbar, sacral, and coccygeal regions, contributing to the peripheral nervous system.
Nerve Supply to Organs
- The vagus nerve supplies respiratory and digestive organs.
- It plays a key role in autonomic control, impacting functions such as heart rate and digestion.
