Role of Vibrissae?
Filters the Air
At what level does the trachea begin?
C6
What are the lobes of the right lung
Superior/upper
Inferior/lower
Middle
What is the name of the ridge of cartilage located at the bifurcation of the trachea into the primary bronchi, which triggers the cough reflex when irritated?
Carina
Where are the apices of the lungs located
Above the clavicles
Parts of Upper respiratory tract (4)
Nose, Paranasal sinuses, Pharynx, Larynx
At what level does the trachea bifurcate?
Lower border T4 (level of sternal angle)
Name 3 impressions found on the left lung
Aortic Arch, Thoracic Aorta, Heart
What artery lies on top of the parietal pleura and from which artery does it arise.
Internal thoracic and it arises from subclavian
What are the fissures of the right lung
Horizontal and oblique
Recess above and below Superior nasal concha
Above: Sphenoethmoidal recess
Below: Superior Meatus
What are the surfaces of the lung
Diaphragmatic
Costal
Mediastinal
Name two impressions found on the right lung
Superior vena cava, azygos vein
What type of innervation does parietal pleura receive
Somatic sensory
In a transverse section of the thorax what is most anterior
Sternum
Which Sinus might provide surgical access to the pituitary gland?
Sphenoid
What type of muscle is trachealis muscle
Smooth muscle
Note the close proximity of the larynx and pharynx, what clinical problem may this pose
Ingested materials may pass through the laryngeal inlet and enter the lungs - aspiration
Internal thoracic had two terminating branches what r they
Musculophrenic and superior epigastric
What other structures enter and exit the lungs at the hilum?
Bronchial Vessels, Lymphatics, Autonomic nerves
Name all the Sinuses (4) and what may be the function?
Sphenoid
Frontal
Ethmoid
Maxillary
(Lighten the weight of the skull, resonance of sound)
What is found in the walls of the trachea that ensures that it remains open at all times?
Horseshoe shaped rings of cartilage
What mechanism ensures that food does not pass down into the airways during swallowing?
The epiglottis is pushed backward by the food and the pharynx and larynx are elevated so that the epiglottis covers the laryngeal inlet. The vocal cords are abducted to close the glottis
name of the potential space at the junction of the diaphragm and rib cage, where fluid can collect in the pleural cavity?
Costodiaphragmatic recess
Structures found on the mediastinal surface of the lungs
Primary Bronchus
Pulmonary veins
Pulmonary arteries
