Anatomy: mandible, maxilla, sections of skull, isthmus of thyroid just the part that crosses in front of the cartilage, sternum (manubrium, sternocleidomastoid (divides neck into 2 triangles) Does the persons" head look like it fits the body. Face should be symmetrical (no drooping on one side) Parotid glands (swelling person will have an enlarged cheek) Asymmetrical face indicates stroke, bell"s palsy (cranial facial nerve 7 is impaired or severed) Neck should also be symmetrical; if it is not, can indicate cancer because tumour can shift it or collapsed lung. Rom of the neck; rule out nuchal rigidity (able to do flexion, extension, etc. without any pain) Thyroid gland should be inspected/palpated with two hands. Expectation is that you should find a smooth gland between fingers; concerns when it is bumpy/rocky/very large. If there is an infection, nodes will be small, smooth, mobile, and tender. Larger than 2cm, they are fixed, firm concern about cancer.
