: 4. The parathyroid glands receive arterial supply from the superior thyroid gland. FALSE?- parathyroid glands are supplied by the inferior thyroid ARTERY.
: 5. Thyroidea IMA is a common, but, nonetheless, anomalous, artery to the parathyroid glands. FALSE- thyroidea ima is NOT common, and it supplies the inferior portion of the thyroid glands.
: 6. The superior laryngeal nerve innervates the cricothyroideus muscle. TRUE - the external branch.
