Sarcopenia, defined as age-associated loss of skeletal muscle mass and function, often reduces muscle mass by about 30% from early adulthood to age 80, usually at a rate of 0.5% to 1.0% per year. There are many factors, such as the individual's activity level and rate of metabolism, involved in the rate of depletion.

Skeletal muscle loss experienced by the elderly is known as sarcopenia. It is a natural part of the aging process and is characterized by a decrease in muscle mass, strength, and function. Sarcopenia can result in decreased mobility, balance, and overall physical performance, leading to an increased risk of falls and loss of independence. Regular exercise, especially resistance training, along with a balanced diet can help mitigate the effects of sarcopenia.

What is the term used for astronauts loss of muscle mass?
atrophy
What is the disadvantage of nerve grafting?
A disadvantage to nerve grafting is that a loss of function or sensation is experienced from the donor nerve site.
What is occular?
loss the abilty to control occular muscle(muscle that controlling our eyeball)
How do dehydration and salt depletion lead to muscle cramps?
Loss of fluids and salts--especially sodium, potassium, magnesium, and calcium--can disrupt ion balances in both muscle and nerves. This can prevent them from responding and recovering normally, and can lead to cramp.
What happens with demyelination and denervation?
Demyelination and denervation bring about muscle weakness, loss of sensation, or paralysis because the affected nerves cannot transmit signals to muscles.
What is the skeletal muscle loss experienced by the aging population?
Sarcopenia
Age-related loss of skeletal muscle mass?
sarcopenia
Is loss of its nerve supply would cause denervation atrophy and paralysis of the skeletal muscle involved true?
Yes it is true.
How do you make a sentence using the word loss?
A death is often referred to as a loss.The loss of my mother's necklace made me cry.After his house burned down, the elderly man could not deal with one more loss.
How would the loss of acetylcholinesterase from the motor end affect skeletal muscle?
Acetylcholine release is necessary for skeletal muscle contraction, because it serves as the first step in the process, enabling the subsequent cross-bridge formation. A muscle's ability to contract depends on the formation of cross-bridges between myosin & actin filaments. A drug that blocks acetylcholine release would interfere with this cross-bridge formation and prevent muscle contraction
How do you use syncope in a sentence?
Syncope means loss of consciousness. An example of a sentence using it: The elderly lady with low blood pressure stood up too quickly and experienced an episode of syncope.
What are appetite-enhancing drugs?
A diverse group of medications given to prevent undesired weight loss in the elderly and in patients suffering from such diseases as AIDS and cancer, which often result in wasting of the body's muscle tissue as well as overall weight loss.
What is the normal response to excessive loss of body heat in a cold environment?
dermal blood vessels become constricted, sweat glands become inactive, and skeletal muscle contract involuntarily.
What change in the skin can lead to cold intolerence in the elderly?
loss of subcutaneous fat, common in the elderly.

Why does the risk of falls increases in the elderly?
Decreased agility, increased reaction time, loss of muscle tone. Some falls occur due to a fracture that is caused by loss of bone mass. Falls are common in the elderly for a number of reasons; some have neurological or vision problems that are common in the elderly that affect the way they see where they're going and their balance. Others have movement disorders such as Parkinson's disease and arthritis. Most commonly though, the elderly fall because their bones and muscles have started to weaken and deteriorate with age. Also, inactivity caused by other factors can decrease muscle mass and weaken the muscles it takes to walk, balance, and stand up straight.
I heard skeletal muscle cells don't divide. Does that mean that people with long term anorexia or people who experienced long term starvation would have permanent muscle loss?
Skeletal muscles cells can divide, but not nearly like what skin or other organ cells can. Mostly, muscle cells can expand ("building" muscle). With anorexia, muscles often become thin, wiry, and lean. They can easily "re-bulk" up, though, if the person resumes eating normally. In very extreme cases of anorexia, though, a person has no energy or fat cells left in their body. In these rare instances, the body will begin to metabolize what is left of the thin muscles cells in order to obtain enough energy to survive. In this case, many of those muscle cells can never re-grow again once they have been metabolized by the body.
