Flashcards in Surface Features Deck (10):

Lines: midsternal, parasternal, midaxillary, midclavicular, paravertebral, scapular

Scapular: thru inferior angle, marker for brachial plexus palsy

Midclavicular: marker for PMI (5th intercostal, mitral valve)

Midaxillary: marker for thoracentesis (9th intercostal) & V6 electrode, chest tube in ptx (6th intercostal)

Paravertebral: assoc w/ tips of transverse processes

Parasternal: L 6th intercostal = marker for pericardiocentesis, L 2nd intercostal = pulmonic valve


Intercostal Spaces

2nd left (pulmonic), right (aortic)

4th lower left sternal border (tricuspid), 5th left, just medial to midclavicular line (mitral)

5th @ midclavicular line, just below nipple (apex)

4-6th along left sternal border (cardiac notch, pericardiocentesis)


C7 spinous process (vertebra prominens)

Most visible superficially

base of the neck


Median Furrow of back

overly spinous processes

begins superiorly in cervical region, ends w/ gluteal cleft


Iliac Crest

highest point = L4 where LPs can be done

palpation of kidneys


Posterior Superior Iliac Spine


Triangle of Auscultation

inferior trapezius, latissimus dorsi, medial border of scapula

lungs can be more easily heard d/t thinning of musculature of back

accentuated by pt leaning forward and folding arms across chest


Lumbar Triangle

Inferior Lumbar Triangle- iliac crest, external abd oblique, latissimus dorsi

Superior Lumbar Triangle- quadratus lumborum, T12, internal abd oblique

-sites of herniation (superior more commonly), inferior more superficial



Unilateral area of skin innervated by sensory fibers from a single spinal nerve


Axillary Tail of Breast

"tail of spence": extension of breast tissue into the axilla,

masses may develop in this tissue, which doesn't appear to be a part of the breast,

higher incidence of cancer in the axillary tail, must be checked during exams
