Name the arteries that supply the thyroid gland (3 marks)

The thyroid gland is primarily supplied by three arteries:

1. Superior Thyroid Artery: This is the first branch of the external carotid artery. It supplies the upper part of the thyroid gland.

2. Inferior Thyroid Artery: This artery arises from the thyrocervical trunk, which is a branch of the subclavian artery. It supplies the lower part of the thyroid gland.

3. Thyroidea Ima Artery: This artery is not always present, but when it is, it arises from the brachiocephalic trunk or the aorta. It also supplies the lower part of the thyroid gland.
