Introduction
Hey readers! Welcome to our complete information to AP Psychology Unit 2: Organic Bases of Conduct. This unit delves into the fascinating intersection of psychology and biology, exploring the methods by which our mind and physique affect our ideas, emotions, and actions.
As you embark on this journey, keep in mind that understanding the organic foundations of conduct is essential for greedy the complexities of human psychology. Let’s dive proper in!
Part 1: The Nervous System

Neurons have three primary elements: the cell physique, dendrites, and axon. The cell physique homes the nucleus and different organelles. Dendrites obtain alerts from different neurons, whereas the axon transmits alerts to different neurons or goal organs.
Neurotransmitters: The Chemical Messengers
Communication between neurons happens via the discharge of chemical messengers generally known as neurotransmitters. These molecules bind to receptors on the dendrites of goal neurons, triggering particular responses. Frequent neurotransmitters embody serotonin, dopamine, and norepinephrine.
Part 2: The Mind
Construction of the Mind
The mind is the central organ of the nervous system, chargeable for controlling a variety of features. It’s divided into three primary areas: the cerebrum, cerebellum, and brainstem.

The brainstem regulates fundamental life features like respiratory and coronary heart charge.
Localization of Perform
