Answer 1

D
Explanation: External jugular. The external jugular vein is formed by the union of the posterior auricular vein and the posterior branch of the retromandibular vein just below the lobe of the ear.

Question 2

Answer 2

D
Explanation: Hyoid. The hyoid bone is a floating bone just below the mandible. It is a U-shaped bone with the prongs of the U facing posteriorly.
