2) first branchial pouch
3) second branchial arch

Answer 1

Lingual thyroid and thyroglossal duct cysts are due to anomalies of the second branchial arch.

Step-by-step explanation:

Lingual thyroid and thyroglossal duct cysts are due to anomalies of the second branchial arch. These structures are formed during embryonic development and are associated with the development of the thyroid gland and its related structures. The second branchial arch gives rise to various structures in the throat and neck region, including the thyroid cartilage of the larynx and the thyroid gland itself.
