🎥 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 review the key terms for AP Psychology Unit 1.2, covering the Nervous System and its role in behavior and mental processes. Each term will be explained with a definition and real-world example, helping you master key concepts for multiple-choice questions and FRQs on the AP Psychology Exam! ✔️ Key terms and concepts covered include: Divisions of the Nervous System • Central Nervous System (CNS): The brain and spinal cord, responsible for processing and interpreting sensory information. • Peripheral Nervous System (PNS): The network of nerves outside the CNS that connects the brain and spinal cord to the rest of the body. Subdivisions of the Peripheral Nervous System • Somatic Nervous System (SNS): Controls voluntary movements of skeletal muscles (e.g., raising your hand in class). • Autonomic Nervous System (ANS): Controls involuntary functions like heartbeat and digestion. • Sympathetic Nervous System: Activates the body’s fight-or-flight response (e.g., increased heart rate when facing danger). • Parasympathetic Nervous System: Calms the body and restores homeostasis after stress (e.g., slowing heart rate after danger passes). Types of Neurons & Their Functions • Sensory Neurons (Afferent Neurons): Carry information from sensory receptors to the CNS (e.g., detecting heat from a hot stove). • Motor Neurons (Efferent Neurons): Send instructions from the CNS to muscles and glands (e.g., moving your hand away from a hot stove). • Interneurons: Located in the CNS, they process information and connect sensory and motor neurons. The Role of Reflexes • Reflex Arc: An automatic response to a stimulus that bypasses the brain for quick reaction time (e.g., knee-jerk reflex). Neural Communication & The Nervous System • Neurons: The basic building blocks of the nervous system that transmit information. • Neurotransmitters: Chemical messengers that communicate between neurons (e.g., dopamine, serotonin). • Synapse: The gap between neurons where neurotransmitters are released. • Action Potential: The electrical impulse that travels down the axon to trigger neurotransmitter release. 💡 This video provides clear explanations, real-world examples, and study strategies to help you apply these terms in AP Psychology exam questions.
