📖 1. Nervous and hormonal system functions and interactions

🔑 Key Concepts & Definitions

• Nervous system: biological network that transmits rapid electrical signals through neurons to coordinate immediate responses.
• Hormonal system: network that releases chemical messengers (hormones) into the bloodstream for slower, longer-lasting regulation.
• Neurotransmitters: chemicals that transmit signals across synapses between neurons.
• Interaction: the nervous and hormonal systems work together to maintain homeostasis by combining fast electrical signals and slow chemical signals.

📝 Essential Points

• The nervous system transmits rapid electrical signals via neurons to coordinate immediate responses.
• The hormonal system releases chemical messengers into the bloodstream for slower, sustained regulation.
• Neurotransmitters are chemicals that carry signals across synapses between neurons.
• The nervous and hormonal systems interact to regulate body functions by integrating quick and prolonged responses.

💡 Key Takeaway

Understanding how these systems coordinate fast and slow responses is essential for grasping physiological regulation.
