00:01 All right, so let's do one quick question to review some of the content that we've covered. 00:06 Which of the following is true? A. Epitrochlear nodes are located just distal to the medial epicondyles. 00:14 B. The thoracic duct drains into the left-sided great vessels. 00:18 C. The vertical chain of inguinal lymph nodes drains the genitals. 00:22 Or D. Virchows node is associated with right-sided lung cancers. 00:30 So Epitrochlear nodes around your elbow are actually located just proximal to the medial epicondyles just medial to the end of your biceps muscle. 00:41 The thoracic duct does in fact drain into the left-sided great vessels, that's going to turn out to be our correct answer. 00:49 The vertical chain of inguinal lymph nodes actually drains the lower extremities whereas the horizontal chain is going to drain the genitals. 00:58 And a Verchows node up here in the left supraclavicular fossa is actually associated with left-sided of cancers, any cancers in the abdomen and then of course, any cancers in the lower extremities, whereas a right sided lung cancer typically would drain up into the right great vessels. 01:14 So the answer is B.
The lecture Quick Review: Examination of the Lymphatic System by Stephen Holt, MD, MS is from the course Examination of the Breast and Lymph System.
