12 (favorite number!)
Name the 3 parts of the sternum from top to bottom
Manubrium
Sternal body
Xiphoid process
3 subdivisions of the thoracic cavity and what they contain
Mediastinum - pericardial cavity, thymus, trachea, esophagus, blood vessels
Pericardial cavity - heart
Pleural cavity - lungs
4 components of UPPER respiratory tract
Sphenoidal sinus
Frontal sinus
Nasal cavity
Pharynx
4 components of lower respiratory tract
Larynx (voice box)
Trachea
Bronchi
Lungs
The – aka – connects pharynx (throat) to trachea
Larynx aka voice box
The – is anterior to the esophagus (just feel your throat)
Trachea
Because the – primary bronchus is wider and more vertical, foreign particles are more likely to be lodged here
Right primary bronchus
The right primary bronchus divides into – secondary bronchi
3
Name the lobes of the right and left lungs
Right : superior, middle, inferior
Left : superior, inferior
The – nerve is anterior to the root of the lung and Innervates the diaphragm
Phrenic nerve - anterior
C3 C4 C5, keep the – Alive!
Diaphragm
The – nerve is posterior to the root of the lung
Vagus nerve
what happens in Vegas stays in vegas
The – pleura tightly adheres to the outside of the lung (innermost serous membrane)
Visceral pleura
The – of the lung rests inferiorly on the diaphragm
Base
The – is the superior most portion of the lung and projects slightly superior and posterior to the clavicle
Apex
The anterior, lateral and posterior lung surfaces are adjacent to the ribs and referred to as – surface
Costal surface - ribs
Along the mediastinal surface of each lung is a depression called the – aka – where bronchi, pulmonary vessels, nerves pass in & out of lungs
Root / hilum
The left lung is – than right lung
Left lung is smaller than right (there is nothing left!)
The left lung has 2 lobes, divided by the – –
Oblique fissure
Name the 2 indentations of the LEFT lung and where they are located
Cardiac impression - made by heart on the medial surface
Cardiac notch - anterior indented region
The right lung has – lobes and – fissures called
Right lung: 3 lobes and 2 fissures (oblique & horizontal fissures)
During inhalation, diaphragm moves –
Exhalation = thoracic cavity increases = diaphragm moves INFERIORly
The – m elevates the ribs in inhalation
Scalene
“Scale high elevations”
