Topics marked <strong>(E)</strong> denote detailed focus typically reserved for Extended grades (e.g., full endocrine pathway analysis).</p> <hr> <h2 id="overview-coordination-principles">Overview: Coordination Principles</h2> <p>Coordination ensures organism survival. Requires communication systems to detect stimulus and initiate response.</p> <ul> <li><strong>Detection:</strong> Stimulus received by <strong>Receptors</strong>.</li> <li><strong>Processing:</strong> Signal processed in the Central Nervous System (CNS) or Endocrine system.</li> <li><strong>Response:</strong> Action initiated by <strong>Effectors</strong>.</li> </ul> <h2 id="system-1-nervous-coordination-fast-response">System 1: Nervous Coordination (Fast Response)</h2> <p><strong>Mechanism:</strong> Electrical impulse transmission via neurons. Very rapid response time. <strong>Pathway (Reflex Arc):</strong> Receptor $\rightarrow$ Sensory Neuron $\rightarrow$ CNS $\rightarrow$ Motor Neuron $\rightarrow$ Effector.</p>
