Question

Berry’s ligament is also known as
(a)Cricoid cartilage
(b)Suspensory ligament of the thyroid gland
(c) The Thyroid cartilage
(d)None of the above

Answer 1

Hint: Berry’s ligament is the ligament that is mainly attached to the cricoid cartilage, and can extend to the thyroid cartilage. Berry’s ligament is present near the middle and center of the neck.

Complete answer:
-A suspensory ligament passing from the thyroid gland to the trachea is the suspensory ligament of the thyroid gland or Berry's ligament.
-A thin layer of fascia, which is distinct from the thyroid capsule, covers both the trachea and the thyroid. -Subsequently, the investing fascia fuses with the thyroid capsule, forming a dense suspensory ligament known as the Berry ligament for the thyroid gland.
 -With swallowing/deglutition, the thyroid gland and all thyroid swelling shift as the thyroid is attacked by the suspensory ligament of Berry to the cartilage of the larynx.
-The thyroid gland is also prevented from sinking into the mediastinum by the Berry ligament.
-The cricoid cartilage helps to maintain the patency of the airway, forms part of the larynx, and provides an attachment point for key muscles, ligaments, and cartilage that act for sound production in the opening and closing of the vocal cords.
-The cricoid cartilage is a hyaline cartilage ring that encircles the trachea completely and composes the laryngeal skeleton's inferior-most boundary.
-The word "cricoid" (Greek, krikos, meaning "ring-shaped") refers to the similarity of the cricoid cartilage to the signet-ring.
So, the correct answer is ‘Suspensory ligament of thyroid gland’.

Note: -The largest and uppermost of nine cartilages inside the larynx, or voice box, is the thyroid cartilage that forms Adam's apple. (A solid but flexible tissue is cartilage.) It contains the vocal folds, also referred to as the vocal cords.
