STEP 2

Add the laryngopharynx

STEP 3

Add the oropharynx

STEP 4

Add the cricoid cartilage

STEP 5

Add the trachea

STEP 6

Add the thyroid gland and parathyroid glands

STEP 7

Using the Dissect tool, you will need to dissect away the thyroid gland to visualize the very small parathyroid glands. Now find the 3 visible parathyroid glands on this cadaver. Notice how integrated the parathyroid glands are within the thyroid gland.

Add the hyoid bone

STEP 9

Add the mandible

STEP 10

Add the clavicle and sternum

STEP 15

Add the mylohyoid

STEP 16

STEP 19

Add the thyrohyoid.

STEP 20

Add the sternohyoid

STEP 21

Add the inferior and superior bellies of the omohyoid
