What are the types of aging?
Biological aging, psychological aging, and social aging.
What is biological aging?
It involves how the body functions and changes over time it relies heavily on metabolic changes.
What are the two types of metabolic changes involved in biological aging?
Anabolism and catabolism
What is anabolism?
It is the body building to peak potential and occurs from birth to an age that varies by individual
What is catabolism?
It is the bodies usually slow deterioration from peak through an individual's death
What is psychological aging?
It is one's perception of personal age.
What is social aging?
It is how one's chronological age is viewed within the societal or cultural context and is affected by the location and socioeconomic status
What are the ways that the theories of human development can be categorized?
Nature versus nurture
continuous development versus discontinuous development
active versus reactive
What are the two parts of the central nervous system?
The brain and the spinal cord
What is the peripheral nervous system?
It is the network of nerves that connects the central nervous system to the rest of the body
What is myelination?
Insulation of neurons to enhance speed of neural transmissions
At what age is a persons brain about 25% of its mature adult size and weight?
At what age is a persons brain approximately 60% of its adult weight?
By the end of the first year.
By about what age does the brain begin to shrink?
By about age 30.
At what age is a persons brain about 80% of its adult weight?
By the end of the second year
By what age is a persons brain it's full adult size
By age 16
At what point does a persons brain diminish by 20% less weight than it was at 30 years old?
By the late 80s.
What are the three parts of the brain
The hindbrain, the midbrain, and the forebrain.
What is the hindbrain responsible for?
Life maintenance and survival functions.
What are the parts of the hindbrain?
and reticular activating system
What does the Medulla oblongata do?
It regulates the heart and breathing
What does the cerebellum do?
It regulates balance
What does the Pons do?
It connects the left and right cerebellum
What does the reticular activating system do?
It regulates arousal and attention
What does the midbrain do?
It connects the hindbrain and forebrain, controls eye muscles, and relays auditory and visual information to the brain centers for higher level thinking.
What does the forebrain do?
It consists of the cerebrum, which is responsible for higher order behavior and conscious thought.
It consists of the left and right hemispheres, the corpus callosum, and the cerebral cortex.
What does the brains left hemisphere do?
It controls the right side of the body and is responsible for language and writing abilities and logical and systematic that.
What does the brains right hemisphere do?
It controls the left side of the body and is responsible for muscle abilities, imagination, and emotional expression.
What does the corpus callosum in the brain do?
It is a bundle of nerve cells that connects the two hemispheres and allows them to integrate cognitive, emotional, and bodily functions.
