🎥 AP Psychology 2025 Study Guide: Unit 1.2 - Overview of the Nervous System 🎥 Link to all 5 units - https://www.teacherspayteachers.com/P... In this video, I’ll break down AP Psychology Unit 1.2: Overview of the Nervous System, explaining how the Central Nervous System (CNS) and Peripheral Nervous System (PNS) work together to control behavior and mental processes. Understanding this unit is critical for acing multiple-choice questions and FRQs on the AP Psychology Exam! ✔️ Essential knowledge covered includes: 🧠 The Nervous System’s Role in Psychology • What is the Nervous System? The body’s communication network, transmitting signals between the brain, spinal cord, and body. • How does it impact behavior? It controls everything from reflexes and movement to memory and emotions. 🔹 Central Nervous System (CNS) - The Body’s Command Center • Brain: Processes information and directs behavior. • Spinal Cord: Transmits signals between the brain and the body, controls reflexes. 🔹 Peripheral Nervous System (PNS) - The Body’s Messenger • Connects the CNS to the rest of the body. • Somatic Nervous System (SNS): Controls voluntary movements (e.g., walking, grabbing an object). • Autonomic Nervous System (ANS): Regulates involuntary functions (e.g., breathing, heart rate). 🔹 Autonomic Nervous System (ANS) - Two Opposing Forces • Sympathetic Nervous System (Fight-or-Flight Response): Increases heart rate, dilates pupils, releases adrenaline in response to stress. • Parasympathetic Nervous System (Rest-and-Digest Response): Slows heart rate, promotes digestion, returns body to homeostasis. 🔹 The Three Types of Neurons • Sensory Neurons (Afferent): Carry sensory info to the CNS (e.g., detecting heat from a stove). • Motor Neurons (Efferent): Send signals from the CNS to muscles (e.g., moving your hand away from a hot surface). • Interneurons: Connect sensory and motor neurons in the spinal cord, processing reflexes before they reach the brain. ⚡ Neural Communication & Reflexes • Neural Transmission: Signals travel through neurons via electrical impulses (action potentials) and chemical messengers (neurotransmitters). • Reflex Arc: A rapid, automatic response to stimuli that bypasses the brain for faster reactions (e.g., knee-jerk reflex). 💡 This video provides clear explanations, real-world examples, and study strategies to help you apply these concepts in AP Psychology FRQs and multiple-choice questions.
