Document Summary
The causes of childhood disorders: developmental psychopathologists study the potential causes of childhood disorders from multiple levels of analysis, genes, brain structure and functioning, psychological processes, thoughts. Feelings: actions, family environment, broader social-cultural experiences. Sex cells form differently, in a process called meiosis. Just as in mitosis, chromosome pairs split and duplicate themselves: however, in meiosis, the chromosome pairs line up and exchange genetic material with each other, a process called recombination. Five principles of brain development: the brain consists of 100 billion neurons, neuron- a nerve cell that is typically very narrow and very long, most are small, vary in length, very numerous, the center contains the cell body. Its main purpose is carry out basin metabolic functions for the cell: the neuron also has dendrites. Fingerlike appendages that receive information from either side outside stimuli or other neurons. In the synapse, neurotransmitters can be detected by other neurons, causing them to change their electrical charge.
