Study Notes
Introduction to Psychology
- Psychology studies behavior, mental processes, and the concept of the soul.
- Encompasses four main goals: Describe, Explain, Predict, Control.
Biological Perspective
- Centers on the function and structure of the nervous system and neurons.
- Neuroscience examines the roles of neurons in behavior and mental processes.
Nervous System
- Composed of specialized cells that convey information throughout the body.
Structure of Neurons
- Dendrites: Receive messages from other neurons.
- Soma: Also known as the cell body, contains the nucleus.
- Axon: Transmits neural messages away from the cell body to other neurons.
- Axon Terminals: Branches at the end of axons that communicate with other neurons.
- Synaptic Knobs: Round areas on axon terminals where neurotransmitters are released.
Supporting Cells
- Glial Cells: Provide support, deliver nutrients, and produce myelin for neurons.
- Myelin: A fatty substance that insulates axons, speeds up neural impulses, and clears waste.
Neural Activity
- Resting Potential: The state of a neuron when it is not actively transmitting information.
- Action Potential: The rapid release of energy that occurs when a neuron fires.
Neuron Communication
- Involves the sending of messages between neurons, essential for all neural activity.
