Which of the following statements is true?
At the beginning of adolescence, girls tend to be as tall as or taller than boys their age.
Which of the following statements regarding sleep during childhood is NOT true?
Children who do not get enough sleep are more likely to have mothers with health problems.
Which statement summarizes normal brain development during the seventh decade of life?
Dendritic growth might compensate for the possible loss of neurons.
Which was NOT a finding of the research involving the Sisters of Notre Dame in Mankato?
Idea density was negatively correlated with brain weight.
Adults need six hours of sleep to be able to function optimally.
Boys become more satisfied with their bodies as they move through puberty while girls tend to become more dissatisfied with their bodies.
Climacteric is the term used to describe the midlife transition in which fertility declines.
Dendritic growth can occur in human adults.
During early childhood, boys have more fatty tissue than girls.
In boys, increased height is associated with an increase in testosterone.
In the first several days of life, most newborns lose 5-7 percent of their body weight.
Neurogenesis in the occipital lobe of a human being is possible.
Recent research suggests that the brains of aging adults may decrease in lateralization, while the brains of children increase in lateralization.
Research involving the Sisters of Notre Dame in Mankato has revealed that idea density in early adulthood is negatively correlated with cognitive impairment in later adulthood.
SIDS is more common in Eskimos than Caucasian infants.
Testosterone is the main class of female hormones.
The age range of menarche is between 9 and 15 years.
A part of the brain's limbic system that is the seat of emotions such as anger.
cellular clock theory
Leonard Hayflick's theory that the number of times human cells can divide is about 75 to 80. As we age, our cells are less able to divide.
The sequence in which the fastest growth occurs at the top of the body—the head—with physical growth in size, weight, and feature differentiation gradually working from top to bottom.
The midlife transition during which fertility declines.
A large bundle of axon fibers that connects the brain's left and right hemispheres.
A hormone associated in girls with breast, uterine, and skeletal development.
A microbiological theory of aging stating that people age because when their cells metabolize energy, they generate waste that includes unstable oxygen molecules, known as free radicals, that damage DNA and other structures.
Hormones that stimulate the testes or ovaries.
The sex glands, which are the testes in males and the ovaries in females.
hormonal stress theory
The theory that aging in the body's hormonal system can lower resistance to stress and increase the likelihood of disease.
Powerful chemical substances secreted by the endocrine glands and carried through the body by the bloodstream.
A structure in the brain that is involved with eating and sexual behavior.
Specialization of function in one hemisphere or the other of the cerebral cortex.
