What is the most common of all radiographic procedures? - ANSWER-Chest
What is another name for chest? - ANSWER-Thorax
What is the chest? - ANSWER-upper portion of the trunk between the neck and
abdomen
Radiographic anatomy of the chest is divided into how many sections? Name them -
ANSWER-1. Bony Thorax
2. Respiratory System proper
3. Mediastinum
What is the bony thorax? - ANSWER-The part of the skeletal system that provides
framework for the parts of the chest involves with breathing and blood circulation.
What is the term thoracic viscera used to describe? - ANSWER-The parts of the chest,
consisting of the lung and the remaining thoracic organs contained in the mediastinum
Anterior what is located in the chest? - ANSWER-1.sternum (manubrium, body, xiphoid
process)(breastbone)
Superiorly the bony thorax consists of - ANSWER-2 clavicles (collarbone)
2 Scapulae (shoulder blades)
12 pair of ribs that circle the thorax
12 thoracic vertebrae posteriorly
,What does accurate and consistent radiographic positioning require? - ANSWER-
Certain landmarks, or reference points, that can be used to center the image receptor
correctly to ensure that all essential anatomy is include on that specific projection.
Where should these land marks be? - ANSWER-Should be parts of the body that are
easily and consistently located on patients.
What are two landmarks for chest positioning? - ANSWER-Vertebra prominens
Jugular notch
What is the vertebra prominens used for? - ANSWER-Important landmark for
determining the central ray location on a posterioanterior or (PA) chest projection.
Where is the vertebra prominens located? - ANSWER-C7
How can the vertebra prominens be located/palpitated? Easier when - ANSWER-
applying light pressure with the fingertips at the base of the neck. Easier when flexed
What is the jugular notch important for? - ANSWER-important landmark for determining
the CR placement on (AP) chest projections.
How is the jugular notch palpated for? - ANSWER-The deep notch or depression (dent)
on the superior portion of the sternum below the thyroid cartilage.
What can be located using the vertebra prominens and the jugular notch (two
landmarks)? - ANSWER-The midthorax at T7
What is respiration? - ANSWER-the exchange of gaseous substance between the air
we breathe and the bloodstream.
The respiratory consists of the parts of the body which - ANSWER-air passes as it
travels from the nose and mouth into the lungs.
Four general divisions of the respiratory system - ANSWER-1. Pharynx
2. Trachea
3. Bronchi
4. Lungs
the diaphragm is the primary. - ANSWER-muscle of inspiration
Each half of the diaphragm is called a _________? - ANSWER-hemidiaphragm
As the dome of the diaphragm moves downward - ANSWER-the volume in the thoracic
cavity increases.
, Increase in volume decreases the - ANSWER-intrathoracic pressure, creating a sucking
action or negative pressure effect.
What does the negative pressure effect result in? - ANSWER-results in air being drawn
into the lungs through the nose and mouth, pharynx, trachea, and bronchi. (Inspiration)
What is the pharynx? - ANSWER-the structure or passageway that's important to the
respiratory system because air must pass here before entering the respiratory system.
Where does the respiratory system start? - ANSWER-Larynx/voice box.
What is the pharyn also referred to? - ANSWER-Upper airway or upper respiratory tract
Where is the pharynx located? - ANSWER-posterior area between the nose and mouth
above and the larynx and esophagus below
What does the pharnyx do? - ANSWER-serves as a passageway for food and liquids
(as well as air) which is why it's considered part of the respiratory system.
How many divisions does the pharynx have? Name them - ANSWER-1. Nasopharynx
2. Oropharynx
3. Laryngopharynx
What makes up the roof of the oral cavity? - ANSWER-The hard palate and soft palate
What makes up the lower posterior parts of the soft palate? - ANSWER-Uvula which
makes the boundary between nasopharynx and oropharynx
Where is the laryngopharynx located comparted to the larynx? - ANSWER-Above and
posterior
During the acts of swallowing, what does the epiglottis do, which does what? -
ANSWER-Flips down and covers the laryngeal opening which prevents from and fluid
from entering the larynx and bronchi.
What does the esophagus connect? - ANSWER-Connects the pharynx to the stomach
The esophagus is __ is relation to the larynx and traches? - ANSWER-posterior
What are the four parts of the respiratory system? - ANSWER-1. Larynx
2. Trachea
3. Right and left bronchi
4. Lungs
larynx, trachea, bronchi form a - ANSWER-continuous, tubular structure through which
air can pass from the nose and mouth into the lungs.
