RAD 112: Radiographic Procedures I Exam Two Study Guide

The thoracic cavity is surrounded by the walls of the

thorax

The thorax sits between the

neck and abdomen

What is an aperture?

an opening

The thoracic cavity extends from the ___ thoracic aperture to the ____

thoracic aperture

superior, inferior

What anatomic structure separates the thoracic cavity from the abdominal cavity?

diaphragm

What is the job of the bony thorax?

protect the organs within it (heart and lungs)

What is the space between the lungs called?

mediastinum

What are the structures of the bony thorax

sternum, clavicles, scapulae, ribs, thoracic vertebrae

The breast bone is the

sternum

The uppermost part of the sternum is the

manubrium

The connection point between the manubrium and the body is called the

sternal angle

jugular notch, xiphoid, manubrium help with centering

acromioclavicular joint positioning/landmark, the inferior angle of the scapula

The center portion of the sternum is the

body

The inferior portion of the sternum is the

Xiphoid process

The joint connecting the manubrium to the clavicles is called

sternoclavicular

The joint connecting the clavicles to the scapula is called

acromioclavicular joint

the acromion process of the ___ attaches to the clavicle to form AC joints

scapula

Clavicles and Scapulae are both

bilateral

Scapulae

Shoulder blades

coracoid

The head of the humerus sits in the

glenoid fossa

How many pairs of ribs are there?

12

How many thoracic vertebrae are there?

12

The thoracic vertebrae correspond to the

ribs

The spinous process of the seventh cervical vertebrae (C7) is called the
(hump that sticks out on the back of your neck)

Vertebra prominens

Which positioning landmark is used to ensure radiographers are capturing the entire lung field?

vertebra prominens (C7)

Xiphoid process corresponds to which thoracic vertebra?

T10

The inferior angle of the scapula and mid thorax both correspond to which thoracic vertebra?

T7

Three to four inches below the jugular notch is the

mid thorax

What is the Respiratory System’s purpose?

Exchange of gaseous substances

Gas exchange occurs between ___ and _____

air, blood

What are the four divisions to the respiratory system?

pharynx, trachea, bronchi, lungs

What are the three separate parts of the pharynx?

nasopharynx, oropharynx, laryngopharynx

The nasopharynx corresponds to

nose

The oropharynx corresponds to

mouth

What marks the boundary between nasopharynx & oropharynx?

uvula

What is the job of the uvula?

close off the nasal cavity when we swallow

The laryngopharynx corresponds to

What is the larynx?

voice box

The esophagus is part of which system?

digestive

What causes aspiration?

food, liquid, saliva, or stomach acid entering the lungs

the esophagus lies posterior to the larynx and the trachea

the voicebox suspends from the hyoid bone

the larynx extends from C3 to C6

What 2 fused plate-like structures form the anterior wall of the larynx?

thyroid Cartilage

the laryngeal prominence is also known as the Adam's apple and corresponds to c5

ring of cartilage forming the

inferior and posterior wall of

larynx.

cricoid cartilage

What is the job of the epiglottis?

closes airway when swallowing

What is the job of the 20 C-shaped rings of cartilage embedded in the walls of the trachea?

To ensure the airway stays open

The trachea is a fibrous muscular tube located ___ to the ___

anterior, esophagus

The trachea extends from ___ to ___

C6 to T5

What is being shown in this image marked by the letter “A?”

air-filled trachea

What is being shown here?

air-filled trachea

What is being shown here?

esophagus

What is being shown here?

thyroid region

What is being shown here?

thymus region

The tracheal cartilage divides into two portions called the

right and left mainstem bronchi

The point where the tracheal cartilage divides is called the

Carina

The Carina corresponds to level

T5

wider, shorter, vertical

The right mainstem bronchus divides into how many secondary bronchus?

3

The left mainstem bronchus divides into how many secondary bronchus?

2

Secondary Bronchi

• Divide into

bronchioles

erminal bronchioles

give way to

alveoli

Where is oxygen and carbon dioxide exchanged in the blood?

Alveoli

The elastic spongy tissue of the lungs is called the

parenchyma

What allows for expansion and

contraction of the lungs

parenchyma
