Cognitive Neuroscience exam #1 with complete solutions

Cognitive Neuroscience exam #1 with complete solutions Cognitive Neuroscience - answerStudy of the brain and how it relates to complex thoughts and behaviors Neurons - answerCells that carry information from one place to another Sensory Neurons - answerBring information to the central nervous system Interneurons - answerassociate information within the central nervous system Motor neurons - answersend information from the brain and spinal cord (CNS) to the muscles Three main parts of neurons - answerCell body, Axon, and Dendritic Tree Cell body - answerContains the nucleus and other cellular machinery necessary for cell functioning Axon - answerCarries information from the cell body to the synapse Dendritic Tree - answerreceives input from the other cells or neurons Glia or Glial Cells - answerServe as "support cells" and do not convey info like neurons, but do have many functions 4 main functions of Glia - answer1. They can modify environment for neurons 2. They can remove dead neurons 3. Some Glial cells myelinate axons 4. Some Glial cells help maintain the blood/brain barrier Gray matter - answerIs made of Neuronal cell bodies (pink part of the brain) White matter - answerLots of myelination from glial cells; areas of the brain that are connecting neurons to other neurons (whitish part) Central Nervous system - answerbrain and spinal cord Peripheral Nervous system - answerAll neural tissue beyond the central nervous system. Neurons that relay information to and from CN
