Answer:

Our ear consists of

1 Outer ear (pinna) which passes through auditory canal leading to the ear drum (tympanum)

2 The middle ear consists of three tiny bones malleus, incus and stapes. the three bones are collectively called ear ossicals.

3 Inner ear or membranous labyrinth has two main parts-- cochlea and spiral-shaped, and semicircular canals.

The pinna collects the sound waves and conducts them through the external auditory canal. They finally strike on the ear drum which is set into vibration.

TEA [102]

Greater decreases in overall brain volume in later adulthood is associated with an unclear exact relationship in cognitive abilities and cognitive functioning.

<h3>How brain changes in late adulthood?</h3>

The brain's size reaches roughly 90% of its adult volume by the time a child is six years old. The brain begins to contract in our 30s and 40s, and by the time we reach our 60s, the brain is contracting even more rapidly. The brain begins to change in appearance, just like wrinkles and gray hair do later in life.

The brain actually shrinks and its overall mass decreases as adults. There are decreases in some neurotransmitters as well, including dopamine and acetylcholine. Loss of memory for recent events, familiar names, and familiar duties is the first sign of Alzheimer's disease. In old age, general knowledge memory does not deteriorate. There has been a deterioration in episodic and event memory.

arlik [135]

Explanation:

  • Besides auscultation including its heart, a stethoscope was being used, and therefore its head may necessitate single or sometimes two diaphragms that encourage the hearing of low as well as high frequencies.  
  • Heart auscultation could perhaps facilitate to develop a better understanding of heart rhythm and breathing, valve state of health, and even some clinical distinction irregularities, including certain congenital disorders or chronic serious illness.

Some other three choices do not apply to that same scenario offered. So, the immediate response here is just the right one.
