sleep tends to be deeper in older adults than in younger adults. Normal age-related changes in older adults include a reduced total sleep time and sleep efficiency and shorter less intense and more evenly distributed REM sleep. Older adults tend to nap during the daytime.
As we age we lose height and gain weight. Loss of height is due to compression of intervertebral disks and poor posture early in aging.
What is your theory on how the thinning of gray and white matter might affect?
When observed under the microscope the thinning of the gray matter is due mainly to a loss of neurons and a reduction in the number of synapses. The thinning of the white matter is due to a loss of axons and their myelin sheaths and a loss of glial (support) cells.

a person cannot develop normally without individuating one’s self from others. Which is true regarding personality during adulthood? Broad personality dimensions such as extroversion and neuroticism are fairly stable across adulthood.
Which of the following is a NORMAL age-related change of the nervous system? There is a decline in brain weight and a reduction in blood flow to the brain.
As residual volume increases the vital capacity is reduced and maximum breathing capacity decreases placing older adults at high risk for developing respiratory infections.
Which of these cardiovascular changes is the primary cause of age-related decrements in VO2max? Lower maximal heart rate. How do skeletal muscle arterioles in older individuals compensate for reduced blood flow during exercise?
What changes occur in muscle with aging How do they affect strength and athletic performance?
Age-related changes in muscle
Muscle loses size and strength as we get older which can contribute to fatigue weakness and reduced tolerance to exercise. This is caused by a number of factors working in combination including: Muscle fibres reduce in number and shrink in size.
How does age affect anaerobic function?
The lower anaerobic and aerobic capacities in older versus middle-aged adults may be due to their smaller muscle mass (decreases in number and size of muscle fibers) lower enzyme activity higher RONS generation (6) or a combination of all factors.
Where are the first visible signs of senescence usually observed?
| The first visible signs of senescence may be observed in the: | Collagen Skin |
|---|---|
| A person who seems to thrive on changes in his or her work lifestyle and relationships would most likely be rated high on the personality dimension called: | Big 5 – openness |
Which brain change routinely occurs in late adulthood quizlet?
in late adulthood the brain actually shrinks and total brain mass declines.
Which term describes the gradual physical decline that occurs with age?
Only $47.88/year. What term describes the gradual physical decline that occurs with age? scenescence.
How does personality change with age?
Do personality types change with age?
In terms of mean-level change people show increased selfconfidence warmth self-control and emotional stability with age. These changes predominate in young adulthood (age 20–40). Moreover mean-level change in personality traits occurs in middle and old age showing that personality traits can change at any age.
What changes about us as we get older?
As we grow older we experience an increasing number of major life changes including career transitions and retirement children leaving home the loss of loved ones physical and health challenges—and even a loss of independence. How we handle and grow from these changes is often the key to healthy aging.
As you age your brain and nervous system go through natural changes. Your brain and spinal cord lose nerve cells and weight (atrophy). Nerve cells may begin to pass messages more slowly than in the past. Waste products or other chemicals such as beta amyloid can collect in the brain tissue as nerve cells break down.
The brain shrinks with increasing age and there are changes at all levels from molecules to morphology. Incidence of stroke white matter lesions and dementia also rise with age as does level of memory impairment and there are changes in levels of neurotransmitters and hormones.
Age-related changes in the renal system result in: A decreased ability to clear wastes from the body and a decreased ability to conserve fluids when needed. The risk of bleeding in the skull which increases with age is MOST directly related to: Shrinkage of the brain.
There are several body changes that happen as you get older that may cause a decline in lung capacity: Alveoli can lose their shape and become baggy. The diaphragm can over time become weaker decreasing the ability to inhale and exhale.
Many factors such as malnutrition and the presence of structural lung disease increase the risk of respiratory infection in older individuals. Aging is also accompanied by a gradual decline in many aspects of immune function and waning immunity is thought to be an important risk factor for pneumonia in the elderly.
The changes in the cardiovascular system associated with aging are a decrease in elasticity and an increase in stiffness of the arterial system.
What changes take place in the musculoskeletal system with age?
Muscles may become rigid with age and may lose tone even with regular exercise. Bones become more brittle and may break more easily. Overall height decreases mainly because the trunk and spine shorten. Breakdown of the joints may lead to inflammation pain stiffness and deformity.
How does aging affect the nervous system quizlet?
After age 30: Neurons decrease in number neuroglial cells increase in size and number axon thinning and decrease in number dendrites decrease in number. Longer retrieval time for short term memory categorization and episodic memory.
What are the effects of aging on skeletal muscle?
Aging results in a gradual loss of muscle function and there are predictable age-related alterations in skeletal muscle function. The typical adult will lose muscle mass with age the loss varies according to sex and the level of muscle activity.
How does age affect muscle strength?
Aging process leads to a decrease in muscle mass and strength9 16 22 25. Loss of strength is directly connected with reduction of muscle mass2 11. … Pronounced changes with aging process occur after 50th life year with more than 15% strength loss per decade2 4 11 13 15 16 20 26.
Which of the following changes in body composition typically occurs in aging adults?
Krems et al. [3] recently compared the RMR of young (20–35 y) and older (≥60 y) men and women. Measured RMR was lower in older individuals compared with younger individuals even after adjusting for fat-free mass (FFM) FM and smoking history. They also calculated RMR based on estimated organ masses.
How is the muscular system affected by aging quizlet?
With aging there is a decline in the ability to repair such oxidative damage thereby causing the cascade of events leading to muscular dysfunction. thus Age related sacropenia muscle weakness and reduction in aerobic capacity is a result of loss in functionality of mitochondrial capacity.
What body composition changes typically occur with age quizlet?
The primary changes in body composition that occur with aging are diminished lean body mass increased fat stores and decreased body water.
How does age affect participation in physical activity?
Older people may experience decreasing flexibility strength and general fitness and find it harder to recover from injury. This affects their choice of activity and gentler lower impact sports such as golf bowls and cycling are popular with the older age group.
Older age is associated with a decreased exercise efficiency and an increase in the oxygen cost of exercise which contribute to a decreased exercise capacity. These age-related changes are reversed with exercise training which improves efficiency to a greater degree in the elderly than in the young.
When the thought required for an action has become routine and it appears that most aspects of the task are performed instinctively the performance of the task is: automatic.
Does fluid or crystallized intelligence change with age?
Fluid and crystallized intelligence tend to change throughout life with certain mental abilities peaking at different points. … Crystallized intelligence continues to grow throughout adulthood. Many aspects of fluid intelligence peak in adolescence and begin to decline progressively beginning around age 30 or 40.
