Description 429-435
In birds, morphological structures of floor of the mouth cavity play a vital role in food intake, nutrition and ingestion that
forms the basis for clinical pathology and pharmacology. Hence, complete anatomical knowledge on the mouth cavity, floor
in particular, is essential. In order to clarify certain morphological aspects of development of floor of mouth cavity, here, we
studied the timing of the development of the tongue in the mouth cavity of Chabro chicks. Chick embryos were procured
from the 5th to 21st days of incubation. Results revealed that the tongue occupied the cranial 2/3rd part of the floor of the
mouth cavity and a laryngeal mound was situated caudal to the tongue. The tongue was triangular in shape and was
differentiated into tip, body, and root on the 10th day of incubation. All the biometrical parameters increased with the
advancement of incubation. The length of the tongue increased about 8.5 times from 6 to 21 days of incubation. Between the
10th to 21st day of incubation, the ratio between the length and width of the tip increased from 1.02 to 1.86 and the body and
root decreased from 0.88 to 0.77 and 1.23 to 0.9, respectively. The conical papillae of the tongue developed on the papillary
crest from the 12th day onwards and caudally directed pointed cornified papillae on the mound from the 16th day of
incubation. These papillae were fully developed by the 21st day of incubation and arranged in primary and small secondary
rows. The tongue was completely developed before hatching and ready to collect food.
