An excitation that travels along an axon at a constant speed. On-Off Switch.
Action Potential
Electrically excitable cells in the vervous system that function to process and transmit information.
Chemicals that are used to relay, amplify, and modulate electrical signals between a neuron and another cell.
A chemical naturally produced in the body. A neurotransmitter. Promotes activity levels and facilitates movement.
Plays a role in sleep and mood changes.
An inhibitory neurotransmitter found in the nervous system. Interferes with the process of memory formation.
Includes the brain and spinal cord and it communicates with the rest of the body. Controls behavior.
Central Nervous System
Part of peripheral nervous system. Communicates with the skin and muscles.
Somatic Nervous System

Peripheral Nervous System
2 chains of neurons that cluster to the L & R of spinal cord. Responsible for fight or flight response.
Sympathetic Nervous System.
Axons extending from Medulla and spinal cord to neuron clusters near the internal organs. Decrease HR, promotes digestion, non-emergency functions.

3) Measure the outcome.
4) Develop Conclusions.
Focuses on uncovering the underlying drives and motivations of people.
Psychodynamic Approach.

Humanistic Psychology
Focuses on thinking processes and acquiring knowledge.
Cognitive Approach
What individuals do as a result of consequences of post actions rather than what individuals think.
Behavioral Approach
Explain behaviors such as genetic factors that influence abnormal brain development.
Biological Approach
