EMORY DPT ANATOMY: HEART AND
LUNGS
The thoracic wall surrounds what? - ANS-thoracic cavity
what are the three divisions of the thoracic cavity? - ANS-2 pulmonary cavities
and
meediastinum
what is the mediastinum? - ANS-the area inbetween the two pleural cavities
the pulmonary cavities are filled with what? - ANS-the lungs
what are the two pleura that form the pleural sac? - ANS-parietal and visceral
which pleura is in contact with lung and which is in contact with the cavity? - ANS-the viscera is
attached to the lung while the parietal is attach to the cavity wall
the parietal pleura is named for the part of the wall in which it sits: what are they? - ANS-costal
pleura: around the ribs
mediastinal pleura: around the mediastinum
diaphragmagtic pleura: around the diaphragm
cervical pleura: around the cervical vertebrae posterior to the cavity (also called the pleural
cupula)
what is the space in-between the pleura called? - ANS-pleural cavity
what is the pleural fluid? - ANS-thin layer of serous fluid to lubricate and decrease friction
between the 2 layers of pleura
what are the pleural recesses? - ANS-an area within the pleural cavity where the lung tissue is
not present as close to the parietal layer of tissue forming small pockets
within the parietal pleura there are two innervations.
the costal and peripheral part of diaphragmatic pleura are innervated by what? - ANS-intercostal
nerves
within the parietal pleura there are two innervations.
the central part of the diaphragmatic and mediastinal pleura are innervated by what? -
ANS-phrenic
, the anterior and posterior pulmonary plexuses of the visceral pleura are innervate by what? -
ANS-mixture of vagal (parasympathetic) and sympathetic nerves
Injuries of the cervical pleura etc Moore 120-127 - ANS-the lung and cervical pleura reach
higher in infants due to short necks and the projection of these structures in the adult, injury to
the neck can also cause injury to the lung and pleura causing pneumothorax or air the the
pleural cavity
what is the role of the lung? - ANS-as the essential organ of respiration it oxygenates the mixed
venous blood
what are the parts of the lung? - ANS-apex
base
root (pulmonary ligament)
hilum
what is the hilum? - ANS-the point at which the bronchi, pulmonary arteries and veins, lymphatic
vessels, and nerves enter the lung
what is the pulmonary ligament of lung? - ANS-an area where the pleura form around the
hilum?
what are the difference between the right and left lung? - ANS-the right lung: has 3 lobes
(superior, middle and inferior) and the horizontal and oblique fissure
the left lung: has 2 lobes (superior and inferior) an oblique fissure, lingula; and a cardiac notch
__________ (right and left lung): a line that runs from spinous process of T2 to sixth
costachondral junction - ANS-oblique fissure
__________ (right lung): line that runs down form anterior border of lung along 4th costal
cartilage to oblique fissure - ANS-horizontal fissure
the trachea beings just inferior to what structure? - ANS-larynx
the trachea is made of what substances? - ANS-incomplete cartilaginous rings closed posterity
with connective tissue and smooth muscle.
the trachea descends where? - ANS-through the neck, through the superior inlet of thoracic
cavity, and divides at T4-T5/Sternal angle
what does the trachea divide into? - ANS-right and left bronchus
what are the primary bronchi? - ANS-the right and left deviations of the trachea
