Presence of the Parafollicular Cells in the Thyroid Gland of the One-Humped Camel

The thyroid is an important endocrine glandthat affects many organs of the body. A limited number of works have been doneon the morphological and histological characteristics of this gland in thecamel and controversial debates have been made on the presence ofparafollicular cells. The aim of this study is to investigate the histologicalstructure of the thyroid in the camel and determine the presence ofparafollicular cells in this gland. This study was performed on 20 camels. Thehistological structure of the thyroid was studied using light microscope afterpreparing sections and staining it with Hematoxylin & Eosin, Verhoeff, andToluidine blue. Thyroid gland has follicles of different sizes, follicular andparafollicular cells, and according to our results these cells are formingabout 59.1% and 5% of the gland volume respectively. The large follicles arelocated in the peripheral part of the gland while the small follicles are seenin the central part of the gland. The central parts of the gland have a moreextensive vascular bed than the peripheral parts. This study revealed that thethyroid gland in camel has parafollicular cells, but most of them are presentin the central part of the gland.
