Adults with presbycusis may have difficulty in discriminating fricatives because they have fewer functional nerve cells in the inner ear, which makes the inner ear work harder to process and transmit sound when background noise is present.

This indicates that the inner ear and brain are not effectively communicating with one another.

Presbycusis is the gradual hearing loss that most people experience as they age.

An age-related disorder that is common is hearing loss.

A hearing loss affects 30-35 percent of persons over 65. A hearing loss affects 40–50% of adults aged 75 and older, according to estimates.

Its primary symptom is trouble discriminating fricatives from background noise as the inner ear has to work harder to process and transmit sound when background noise is present because they have less functioning nerve cells.

Define blood pressure. How do you calculate it? What does systolic reading mean? What does systolic reading mean?​
weeeeeb [17]

Answer:

Blood pressure is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in the large arteries.

Explanation:

Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value. diastolic blood pressure of 88 mmHg. When your heart beats, it squeezes and pushes blood through your arteries to the rest of your body. This force creates pressure on those blood vessels, and that's your systolic blood pressure. A normal systolic pressure is below 120. A reading of 140 or more means you have high blood pressure.

Helga [31]

<u>A temporary worsening of the condition</u> indicate that the client is in cholinergic crisis.

An edrophonium injection makes the client in cholinergic crisis temporarily worse. An improvement in the weakness indicates myasthenia crisis. Muscle spasms are not associated with this test.

The main test for myasthenia gravis is a blood test to look for a type of antibody (produced by the immune system) that stops signals being sent between the nerves and muscles. A high level of these antibodies usually means you have myasthenia gravis.

Flaccid paralysis worsens the paralysis caused by cholinergic crisis but strengthens the muscle response in the case of myasthenia gravis.
