Human Embryonic Shoulder Girdle
Semi-schematic drawing of semi-coronal section of right clavicle of an 18 mm. embryo.
All the parts shown save the subclavius muscle were shown in the section drawn, but the subelavitus was added from its appearance in several sections.
Notice how the sternal segment overrides the acromial segment of the clavicle.
