LECOM ANATOMY EXAM 2 COMPLETE
QUESTIONS AND 100% CORRECT
ANSWERS
\Q\.BS of the breast - ANSWERS✔-lateral mammary branch from lateral thoracic
medial branches of anterior intercostal a from internal thoracic
\Q\.Innervation of breast - ANSWERS✔-cutaneous branches of 2-6 intercostal n (nipple is 4th)
\Q\.Intercostal muscle innervation - ANSWERS✔-Intercostal n (ant ramus of T1-T11)
\Q\.function of intercostal muscles - ANSWERS✔-external elevates ribs with inspiration
internal depresses ribs with exspiration
\Q\.subcostal muscle innervation - ANSWERS✔-subcostal n (ant ramus T12)
\Q\.intercostal muscle blood supply - ANSWERS✔-posterior and anterior intercostal areteries
and superior intercostal arteries (first two)
\Q\.venous drainage of intercostal muscles - ANSWERS✔-internal thoracic v > brachiocephallic
or azygos> SVC
(upper two drain directly to brachiocephallic)
\Q\.location of costal vessels - ANSWERS✔-inferior to rib (VAN) superior to inf
,collateral branches lie superior
\Q\.foramen of diaphragm and contents - ANSWERS✔-caual (T8) IVC and rt phrenic n

\Q\.BS of diaphragm - ANSWERS✔-inferior phrenic a on ab surface
pericardiophrnic, muculophrenic and sup phrenic on thoracic surface
\Q\.Innervation of diaphragm - ANSWERS✔-Phrenic n C3-C5
\Q\.pleura extends as - ANSWERS✔-pulmonary ligament
\Q\.sibson's fascia - ANSWERS✔-extension of endothoracic fascia that covers the cervical pleura
and prevents puncture of the lung when injecting at neck
\Q\.endothoracic fascia - ANSWERS✔-overlies pleura to separate it from thoracic wall
\Q\.costodiaphragmatic recess - ANSWERS✔-recess between visceral and parietal pleura that
enlarges with expiration
fluid may pool here and can be drawn out via thoratocentesis
\Q\.location of visceral and parietal pleura @ midclavicular, axillary and midscapular -
ANSWERS✔-6/8 8/10 10/12
,\Q\.right lung vs left - ANSWERS✔-right 3 lobes, bronchus is superior in hilum
left 2 lobes with lingula off superior lobe, pulmonary a superior in hilum
\Q\.location of oblique and horizontal fissures - ANSWERS✔-oblique T4 spine to 6th rib
horizontal rib 4 anteriorly
\Q\.blood supply of lung - ANSWERS✔-bronchial a
\Q\.venous drainage of lung - ANSWERS✔-bronchial v, right goes to azygos and left goes to
hemiazygos
pulmonary v
\Q\.pulmonary embolism - ANSWERS✔-clot from leg to lung causing respiratory distress
\Q\.aspirated foreign body more likely in - ANSWERS✔-right main bronchus because it is more
vertical, wider and shorter
\Q\.adeonpathy at supraclavicular - ANSWERS✔-indicates bronchiogeic carcinoma if on right
side expected in thorax if on the left expected in thorax, abdomen or pelvis
\Q\.innervation of lung - ANSWERS✔-pulmonary plexus
vagus n (constricts, parasymp)
sympathetic trunk (dilates)
\Q\.sternal angle - ANSWERS✔-T4/ T5
trachea bifurcates, arch of aorta begins and ends
, -if patient is standing arch moves inferiorly
azygos v drains to SVC
costal cartilage of rib 2 meets sternum
\Q\.xiphisternal junction - ANSWERS✔-central tendon of diaphragm
T9 if supineT9-T10 if standing
\Q\.pericarditis - ANSWERS✔-fluid in pericardial cavity that can cause cardiac tamponade
(impaired venous flow causing impaired cardiac output
\Q\.transverse pericardial sinus - ANSWERS✔-posterior to aorta and pulmonary trunk, allows for
clamping of the vessels together
\Q\.pericardial BS - ANSWERS✔-pericardiacophrenic (major) musculophrenic, int thoracic, inf
phrenic, thoracic aorta
\Q\.pericardium innervation - ANSWERS✔-phrenic n (C3-C5)[same as diaphragm] causing
referred pain to lateral neck and shoulder
vagus n
sympathetic trunk
\Q\.rough muscle in atrium vs ventricle - ANSWERS✔-pectinate in atrium
trabeculae carne in ventricle
\Q\.RV vs LV valves - ANSWERS✔-right tricuspid left bicuspid with thinner but more chordae
tendinae(try before you buy)
