Study Notes
Thoracic Landmarks Lines
-
Midsternal Line: Vertical reference running down the center of the sternum. Crucial for assessments and procedures aligned with the heart and thoracic cavity.
-
Right and Left Midclavicular Lines: Lines parallel to the midsternal line, originating from the midclavicle. Important for lung examinations as the inferior borders typically intersect the sixth rib at these lines.
-
Right and Left Anterior Axillary Lines: These lines run parallel to the midsternal line starting at the anterior axillary folds, assisting in delineating anatomical regions of the thorax.
-
Right and Left Midaxillary Lines: Also parallel to the midsternal line, these lines begin at the midaxillary area, useful for locating structures within the thorax and for lateral chest assessments.
-
Right and Left Posterior Axillary Lines: These lines mirror the midsternal line and start at the posterior axillary folds, serving as key references for posterior thoracic examinations.
-
Vertebral Line: A vertical line that traces the spinal processes, important for assessing the alignment and health of the spine and surrounding structures.
-
Right and Left Scapular Lines: Parallel to the vertebral line, these lines pass through the inferior angles of the scapula when the patient is in an erect position, providing markers for thoracic surface anatomy.
