Module 4 Flashcards
Cognitive Neuroscience
Involves taking pictures and identifying the structures and functions of the living brain during the performance of a variety of mental or cognitive processes, such as thinking, planning, naming, and recognizing objects.
Zygote
Is a cell that results when an eff is fertilized. a zygote contains 46 chromosomes arranged in 23 pairs.
Chromosome
Is a short, rod like , microscopic structure that contains tightly coiled strands of DNA. Each cell of the human body contains 46 chromosomes in 23 pairs except for sperm and eggs.
Gene
Is a specific segment on the long strand of DNA that contains instructions for making proteins. Proteins are chemical building blocks from which all the parts of the brain and body are constructed.
Polymorphic Gene
Is a gene that has more than one version.
Dominant Gene
Is a type of polymorphic gene that determines the development of a specific trait even if it is paired with a recessive gene. A recessive gene is a type of polymorphic gene that determines the development of a specific trait only when it is inherited from both parents.
Fragile X Syndrom
An inherited developmental disability, is due to a defect in the X chromosome (the pinched end of the X chromosome). It can result in physical changes, such as a relatively large head with protruding ears, as well as mild to profound mental retardation.
Down Syndrom
Results from an extra 21st chromosome ans causes abnormal physical traits and abnormal brain development, resulting in degrees of mental retardation.
Genetic Testing
Involves taking a sample from someone’s blood, hair, skin, or other body part and then examining the person’s genes to look for sign that he or she may be at risk for specific diseases or disorders.
Theory of Evolution
Says that different species arose from a common ancestor and that those species that survived were best adapted to meet the demands of their environment.
