Neurons (nerve cells) excitable cells that transmit electrical signals Glial cells cells in the nervous system that support, nourish, and protect neurons CNS (central nervous system) brain and spinal cord PNS (peripheral nervous system) the sensory and motor neurons that connect the CNS to the rest of the body ...

4 step of neurotransmitters 1. Chemical must be synthesized in the nueron 2. When neuron is active chemical must be released and produce a response in some target 3. A response must be obtained when a chemical is placed on its target 4. A chemical must exist for removing the chemical from its site of action How is ACh synthesized? Use of enzyme "Choline acetyltransferase" Acetly CoA + Choline > enzyme > ACh How is ACh made? Acetyl CoA carries acetate to the transmitter systems i...

Cerebrum Major structure of the forebrain that consists of two virtually identical hemispheres (left and right) and is responsible for most conscious behavior. Hemisphere "Half a Sphere", referring to one side of the cerebrum. Brainstem Central structure of the brain responsible for most unconscious behavior.

Developmental Psychology A branch of psychology that studies physical, cognitive and social changes throughout the lifespan from birth to death, often nicknamed from womb to tomb zygote a newly fertilized egg embryo about 2 weeks after fertilization, this develops as the fertilized egg attaches to the uterine wall and the placenta forms teratogen a harmful agent that can produce developmental malformations (birth defects) during the prenatal period as it is passed from other to child,...

Debate in whether our development is influenced more by our experiences or by our biological parents or environment Nature vs. nurture controversy Eric Erikson, Social experiences through human deveopment Psychosocial Development the name psychologists have given to the physical and cognitive changes that occur throughout a person's life (Boyd & Bee, 2009).

Lifespan development-the field of study that examines patterns of growth, change, and stability in behavior that occur throughout the entire life span -the changes that occur have physical, social, cognitive, and emotional dimensions and are from conception to death Major periods of human development1. Prenatal-conception to birth 2. Infancy and toddlerhood-birth-2 years 3. Early childhood-2-6 years 4. Middle childhood-6-11 years 5. Adolescence-11-18 years 6. Early adulthood-18-40 yea...

Chapter 1 - The Science of Human Development ... What does the science of human development seek to understand?(p. 4) Seeks to understand how and why people -all kinds of people, everywhere, of every age-change over time Do most developmental psychologists believe that development results from nature, nurture, or an interaction of the two?(p. 5) Nature refers to the influence of the genes that people inherit. Nurture refers to environmental influences, beginning with the health and d...

Issues in Developmental Psychology 1. Continuity 2. Sources of development 3. Plasticity 4. Individual Differences Continuity - Is development a matter of quantitative (continuous - a gradual change) or qualitative (stage-like - discontinuous change) change?
