The external jugular vein:


134. Is formed by the junction of the superficial temporal and
    maxillary veins
135. Crosses the sternomastoid to enter the posterior triangle
136. Because it lies beneath the deep fascia, is never visible in
     the living
137. Usually terminates in the subclavian vein
138. Because it lacks competent valves, it is an important
    indicator of pressure changes in the right atrium
