Description
The thyroid gland is a butterfly-shaped organ located in the lower neck anterior to the trachea.
• It consists of two lateral lobes connected by an isthmus.
• The gland is about 5 cm long and 3 cm wide and weighs about 30 g.
• The blood flow to the thyroid is very high (about 5 mL/min per gram of thyroid tissue), about five times the blood flow to the liver. This reflects the high metabolic activity of the thyroid gland.

Anatomy of head and neck
The head is the globular cranial end of the body, which contains brain and special sense organs, viz. eyes for vision, ears for hearing and equilibrium, nose for smell, and tongue for taste. It also provides openings for the respiratory and digestive systems. Structurally and developmentally, the head is divided into two parts: cranium and face.
