The thyroid is an important endocrine gland
that affects many organs of the body. A limited number of works have been done
on the morphological and histological characteristics of this gland in the
camel and controversial debates have been made on the presence of
parafollicular cells. The aim of this study is to investigate the histological
structure of the thyroid in the camel and determine the presence of
parafollicular cells in this gland. This study was performed on 20 camels. The
histological structure of the thyroid was studied using light microscope after
preparing sections and staining it with Hematoxylin & Eosin, Verhoeff, and
Toluidine blue. Thyroid gland has follicles of different sizes, follicular and
parafollicular cells, and according to our results these cells are forming
about 59.1% and 5% of the gland volume respectively. The large follicles are
located in the peripheral part of the gland while the small follicles are seen
in the central part of the gland. The central parts of the gland have a more
extensive vascular bed than the peripheral parts. This study revealed that the
thyroid gland in camel has parafollicular cells, but most of them are present
in the central part of the gland.
