Chapter 2: Chest. Bontrager's RADIOGRAPHIC POSITIONING and RELATED ANATOMY
Hypersthenic
A body habitus that has a broad thorax with very deep from front to back but is swallow in vertical dimension. 5% of population
hypostenic
A body habitus that is average and 35% of the population>?
epiglottis
A cartilage of the larynx that flips down and covers the trachea during the act of swallowing.
epiglottis
A cartilage of the larynx which resembles a leaf with the narrow distal stem portion attached to a part of the thyroid cartilage. need finish.
10
A general rule for average patients. How many ribs needed to be shown on an x-ray?
Sternum
Clavicles is connected to what?
Hemidiaphragm
Each half of the diaphragm is called?
laryngopharynx. stomach
Esophagus starts in what part of the pharynx and ends in what area of the body??
vertebra prominens jugular notch
For chest positioning, what are the two topographic landmarks?
70 to 85 less
For pediatric. How much the technical factors for kV is ------- and ------- mAs are required for pediatric patients with the shortest exposure time possible (to prevent motion).
two
How many inspiration before you start using the x-ray?
110-125 kV
In general, chest radiography uses low contrast, described as long-scale contrast, with more shades of gray. This require a high kV of how much?
Bony thorax Respiratory system proper Mediastinum
Radiographic anatomy of the chest is divided into three sections: These sections are?
hyoid bone
Suspended small bone on the top of the cervical neck is called ------
True
T/F. Always start 11th or 10th ribs when looking at the PA x-ray film or digital PA x-ray
True
T/F. For chest radiography includes the removal of all opaque objects from the chest and neck regions, including clothes with buttons, snaps, hooks, or any objects that would be visualized on the radiograph as a shadow (radiopaque artifact)
True
T/F. In general rule, High kV required the use of grid.
True
T/F. Patients with pulmonary diseases and trauma may be unable to inspire deeply. With that said, it may impossible to demonstrate 10 ribs total.
C5
The laryngeal prominence of the of the thyroid cartilage located at approximately the level of --------is an excellent topographic reference for locating specific skeletal structure in this region
uvula
The lower posterior aspect of the soft palate is called?
laryngeal prominence
The prominent anterior projection of the thyroid cartilage is palpated easily and is known as the ------------
asthenic
This body habitus chest positioning the technologist must ensure that the IR is long enough to include both the upper apex areas
seventh cervical vertebra
Veterbra prominens is also known as
The 2 clavicles
What are the 2 part of the bony thorax that is superior?
1. manubrium 2. body 3. xiphoid process
What are the 3 division of the sternum?
sternum (manubrium, body, xiphoid process)
What are the anterior part of the bony thorax?
Larynx Trachea Bronchi (left and right brochi) Lungs
What are the four parts of respiratory system proper?
nasopharynx, oropharynx, laryngopharynx
What are the three division of pharynx?
Chest x-ray
What is the most common radiographic procedure?
12 thoracic vertebrae
What is the most posteriorly parts of the bony thorax?
Chest Thoarax
What is the upper portion of a bodies trunk between the neck and the abdomen?
The hard palate and the soft palate
What makes up the roof of the oral cavity?
decrease
When the thoracic cavity increases its volume (inspiration), what happen diaphragm? (increase or decrease?)
to minimize the chance of motion and resultant loss of sharpness.
Why in chest radiography requires the use of high mA and short exposure time?
asthenic
a body habitus with the narrow width thorax and swallow from front to back but is very long in its vertical dimension. 10% of population
thyroid cartilage
consist of two fused platelike structures that form the anterior wall the larynx This is also the largest and least mobile part of the larynx. Assist sound making or voice process of the larynx.
Landscape
if the hypersthenic patient chest are too big, where should IR be placed? Portrait or Landscape?
larynx
is a cage like, cartilaginous structure that is approximately 1 1/2 to inches in length in an adult. This is located in he anterior portion of the neck.
Esophagus
is a part of the digestive system that connects the pharynx with the stomach
cricoid cartilage
is a ring of cartilage that forms the inferior and posterior wall of the larynx.
Pharynx
is a structure or passageway that is important to the respiratory system because air must pass through it before entering the respiratory system?
resipiratory
is the exchange of gaseous between the air we breathe and the bloodstream.
Bony thorax
is the part of the skeletal system that provides a protective framework for the parts of the chest involved with breathing and blood circulation.
Thoracic viscera
is the term used to describe these parts of the chest, consisting of the lungs and the remaining thoracic organs contained in the mediastinum. or is defined as the inner organs in the thoracic cavity
Pharynx
it is a passageway for food and fluids as well as air, making it common to the digestive and respiratory system
Pharynx
it is the upper airway or upper respiratory tract?
Adams apple
laryngeal prominence of the larynx is also known as -------
trachea
located just anterior to the esophagus, extends from its junction with the larynx at the level of the C6 downward to the level of the T4 or T5 where it divides into right and left primary bronchi.
vocal cords
sound are made as air passes between the -------- located within the larynx
C3
the upper margin of the larynx is approximately level of what vertebra?
C6
what level of the vertebra that larynx joins to the trachea? Need to finish
