The nervous system is a complex network controlling body functions and responses through electrical impulses, with the importance of spinal cord in body communication being paramount for survival and daily functions.
- The system comprises central and peripheral components, with neurons transmitting messages through electrical signals
- Understanding the role of neurotransmitters in mood and stress is crucial, with key chemicals like serotonin and dopamine regulating various bodily functions
- The autonomic system manages involuntary responses, particularly demonstrating how the nervous system works in fight or flight
- Spinal cord serves as a vital communication highway between brain and body, with damage potentially causing severe impairment
- Neurotransmitters play essential roles in mood regulation, reward pathways, and stress responses
