Histological Structure of the Thyroid Gland in Duck: A Light and Electron Microscopic Study
The present investigation aimed to study the
histomorphometric characterizations of the thyroid gland of the duck.
Five adult male and five adult female ducks were used in the
experiment. Results showed that the overall histological structure of
the thyroid gland of the duck were similar to those of the other
vertebrae. The gland consisted of roughly spherical randomly
distributed micro and macrofollicles with very little interstitial tissue
between them. Each follicle is lined by a single layer of epithelial
cells enclosing a cavity, the follicular cavity, which is filled with
colloid. Ultrastructural findings showed that the apical surface of the
follicular cells bears a variable number of short, irregularly
distributed microvilli which are apparently more numerous on the
columnar cells than on the lower, relatively inactive cells.
Mitochondria and rough endoplasmic reticulum occupy the
subnuclear region of the follicular cell, whereas the Golgi complex,
free ribosomes and colloid droplets were found in the apical
cytoplasm. At light or electron microscopic levels, there was no sex
difference in histomorphometric characteristics of the thyroid
glands.ls.
