Surface marking of internal jugular vein by joining two points between?
Internal jugular vein is marked by a broad line by joining these two points. a. The first point on the neck medial to the lobule of the ear. b. The second point at the medial end of the clavicle. The lower bulb of the vein lies beneath the lesser supraclavicular fossa between the sternal and clavicular heads of the sternocleidomastoid muscle.
