Which of the following feature about thyroid gland is TRUE?

The thyroid is located anterior to the trachea between the cricoid cailage and the suprasternal notch. It weighs 12-20 g, highly vascular, and soft in consistency. Four parathyroid glands are located posterior to each pole of the thyroid. The recurrent laryngeal nerves traverse the lateral borders of the thyroid gland and must be identified during thyroid surgery to avoid injury and vocal cord paralysis. Ref: Harrison, E-18, P-2911
