Question 21

Answer 22

Mandibular salivary gland

Question 23

What is the anatomical landmark for cervical nerve 2?

Answer 23

wing of the atlas

The great auricular nerve is going to supply some cutaneous innervation to the caudal aspect of the ear. There are a ton of different procedures that get done on the ear and we will need good nerve blockage associated with these procedures. You can very easily block the great auricular nerve by palpating the wings of the atlas and doing a block in the area where C2 exits - this will give you a complete blockade of the caudal aspect of the ear.
