Heterotopic salivary tissue and branchial cleft sinus
Abstract:
Bilateral lesions which appeared clinically to be branchial cleft sinuses were removed from a patient's neck. One was indeed a branchial cleft sinus, with elements of salivary tissue, but the other proved to be pure salivary tissue with a duct characteristic of a salivary gland. The embryology and clinical characteristics of heterotopic salivary glands are discussed. The occurrence of a heterotopic gland together with a branchial cleft sinus supports the contention that the heterotopic glands arise through errors of development in the branchial apparatus.

Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
