Data viva — neck cross-section and central venous access
A Primary anatomy data viva — read an axial neck cross-section; give the carotid-sheath contents (carotid medial, IJV lateral, vagus posterior); explain IJV cannulation under ultrasound (compressible vein vs pulsatile carotid, in-plane/out-of-plane); explain right-side preference and the four anatomical complications.

Stimulus
A labelled axial cross-section of the neck at C6 shows the sternocleidomastoid, the trachea and oesophagus, the thyroid lobe, and the carotid sheath containing the internal carotid artery (medial), the internal jugular vein (lateral) and the vagus nerve (between, posterior), with a thin needle line approaching the IJV. Identify the structures, describe the sheath contents, and outline safe IJV cannulation.
