McCoy Ch.7 Questions
What is the axial skeleton?
The portion of the skeleton that consists of the spine and thorax. It houses the respiratory system

What is the appendicular skeleton?
The remainder of the skeleton (arms, legs, pelvis, skull)

What is the dens or odontoid process?
It is the projection from the anterior segment of the axis that inserts into the atlas.

Which vertebrae create the pivot point around which the
skull can be tilted and rotated?
The atlas and the axis
What is the spinous process, where are they located, and
what is their function?
The spinous process is the projection from the posterior of each vertebrae (not the atlas). The muscles of the back attach onto the spinous process.

Describe the size and angle of the spinous processes.
In the lumbar section, the spinous processes are big and stubby, and are nearly a right angle to the spine. The thoracic spinous processes are longer and extend obliquely downward. The seventh cervical vertebrae has a particularly large spinous process.

What are the bones of the pelvis?
the sacrum, ilium, pubis, ishium

How is McCoy’s description of the connection of the ribs to
the sternum different than Malde’s?
Malde discusses more about the slope of the ribs and McCoy doesn't say much about it. McCoy also doesn't discuss the motion of the ribs - up and out.

Describe the parts of the sternum.
The sternum consists of: two bony plates, the manumbrium and corpus and the small projection at the bottom of the sternum called the xiphoid process.

Describe the pleural sacs and their function.
Pleural sacs are what keep the lungs attached to the interior walls of the thorax. Because of this if the thorax changes shape so do the lungs.

What is Boyle’s Law?
Pressure and volume are inversely related
Pressure and volume are inversely related
Expansion OF THE CHEST AND OR ABDOMEN UPON INHALATION CAUSES air
to flow into the lungs; expansion is never the EFFECT of air entering the lungs.
Describe the lungs.
The lungs are made of spongy material. The right lung has 3 lobes and the left lung has 2 lobes. Air comes from the trachea through the bronchial tubes that lead to each lung.

Describe the bronchial tree.
Once divided the bronchial tubes divide into smaller and smaller segments.

Describe the aveolar sacs and their function.
The bronchi end up in the alveolar sacs where the exchange of blood gasses occurs.

Describe the central tendon of the diaphragm.
It is a strong fibrous muscles where the muscles attach to the diaphragm. It is shaped like a boomerang.

How does the range of motion of the diaphragm vary between
quiet breathing and deep breathing?
One and a half centimeters during quiet breathing to six or seven centimeters during deep breathing.
One and a half centimeters during quiet breathing to six or seven centimeters during deep breathing.
How much air is drawn into the lungs in a deep breath?
Two and a half liters
What are the four
principal methods of breath management?
Clavicular (upper chest), thoracic (lower chest), abdominal (belly breathing) and a balanced breath (appoggio)

According to McKinney (quoted here), what is the difference
between breath support and breath control?
They are independent yet related functions. Breath support enables the production of beautiful sounds whereas breath control allows those sounds to last till the ends of phrases.

What are the problems with clavicular breathing for singing?
Because the same muscles the become elevated in clavicular breathing have to drop during exhalation.
