Myelin <em>is the fatty tissue that protects the axon and gives nerves their whitish colour. </em>

<u>Explanation:</u>

The nerve fibers in our 'body' are enclosed by a sheath called Myelin. It has a dual function it gives color to the white matter and guards the nerve fibers against injuries. It also increases the transmission of electrical nerve signals across axons. Axons are extensions of nerve cells called neurons. White matter in the areas of our 'Central Nervous System' are mainly prepared by axons which are also referred to as tracts. White matter is responsible for learning abilities and other brain activities like coordinating message between different parts of the 'brain'.

A healthy 70-year-old woman, admitted to the hospital for a hip replacement surgery, develops an infection after the surgery and
kykrilka [37]

Answer:

Explanation:

ames Brantner had always been scrupulous about maintaining his health. He sees his primary care doctor annually, avoids sweets and developed a habit of walking 3.5 miles every other day near his home just outside Harrisburg, Pennsylvania.

So when a routine colonoscopy in 2017 showed evidence of cancer, Brantner, then 76, was stunned. He’d need 12 radiation treatments, followed by surgery to reconstruct his colon. His physician recommended Johns Hopkins Hospital’s colorectal surgeon Susan Gearhart.

“The surgery [which took place last December] was quite extensive,” says Brantner, a retired planning officer for the Pennsylvania Department of Transportation. “Dr. Gearhart was very upfront with me—and compassionate.” He recalls little about his two days in the intensive care unit, but all went well during the surgery and hospital stay. And, though he’s lost 30 pounds and is not yet able to walk long distances, Brantner says he’s getting his appetite back and feels stronger every day.

More than a third of all surgeries in U.S. hospitals—inpatient and outpatient procedures combined—are now performed on people age 65 and over, according to the Centers for Disease Control and Prevention. That number, 38 percent, is expected to increase: By 2030, studies predict there will be some 84 million adults in this age group, many of whom will likely need surgery.

Last year, across all five adult Johns Hopkins medical centers, 36 percent of surgeries—48,359—took place in the 65-plus population.

Now, Johns Hopkins Bayview—a longtime hub for comprehensive health care of older adults—is poised to become a “center of excellence” in geriatric surgery. This means the American College of Surgeons will likely recognize Hopkins Bayview as offering a high concentration of expertise and resources devoted to caring for older-adult patients in need of surgery, leading to the best possible outcomes. Hopkins Bayview is one of eight hospitals expecting to merit this distinction, which also recognizes extensive research. (The others, which include community hospitals, veterans’ hospitals and academic centers, are Denver Veterans Affairs Medical Center, Kaiser Permanente Fresno, New York University Winthrop Hospital, University of Alabama, University of Connecticut, University of Rochester, and University Hospital—Rutgers’s—in Newark, New Jersey.)

Gearhart is among the leaders championing the program. Others include Perry Colvin, medical director for Peri-Operative Medicine Services; and Thomas Magnuson, Hopkins Bayview’s chairman of surgery, as well as geriatric nurse practitioners JoAnn Coleman, Jane Marks and Virginia Inez Wendel.

Shifting Perceptions of Aging

While advances in technology and medicine make it easier for people to live longer, healthier lives, no one is sure how factors such as chronological age and chronic disease affect geriatric surgical outcomes.

Consider Podge Reed. In 2011, he was 70 years old, trim and still working as chairman of the board of an oil production company. He played golf regularly and was an avid gardener. Then, during an annual physical, he learned that his lungs were impaired. He’d acknowledged having some recent shortness-of-breath episodes and was diagnosed with lung disease of unknown origin. Within a few months, Reed was placed on a transplant waiting list for a new set of lungs.

Four days after being placed on the transplant waiting list, Reed received a call from the hospital: A 41-year-old organ donor had just died, and the victim’s lungs appeared to be suitable for Reed in blood type and body size. The transplant went well, and Reed remained in the hospital for 56 days—longer than usual for most lung transplant patients because of a lung infection.

Androgens and estrogens are hormones that impact the sexual response cycle. Write about the four phases of that cycle and explai
madreJ [45]

Answer:

Females and males each have some amount of the sex hormones, androgens and estrogens. In males however, androgens like testosterone is more dominant and in females estrogens like estradiol are more dominant. The hormones both affect the sexual response cycle. The sexual response cycle has four phases: desire, arousal, orgasm and resolution. The desire phase can last anywhere from a few minutes to hours and includes physical changes like an increase in muscle tension, heartbeats quickening, flushed skin, and an increased flow of blood to genitals. The arousal phase extends to the brink of the orgasm phase, during this phase the changes experienced in the desire phase are intensified along with blood pressure increasing. The orgasm phase generally only lasts a few seconds and is the climax of the sexual response cycle, some characteristics include: Involuntary muscle contractions and spasms, blood pressure, breathing, and heart rate at their highest point, a release of built up sexual tension, and flushed skin. During the resolution phase the body returns to normal, often a sense of wellbeing and fatigue is achieved. To begin the cycle a male need a certain amount of the androgen, testosterone, but high levels in females tend to lead to more sexual thought and desires, typically though, women have relatively low levels of testosterone. In women, estrogens, such as estradiol are more common. Estrogens are produced when a girl starts puberty and helps her reproductive cycle begin. A high level of estrogen in men can lead to a reduced sex drive, loss of hair, or trouble focusing, but a normal level in men is crucial to proper erectile function.
