In birds, the brachiocephalic
artery is the second branch of aorta which gives rise to the common carotid and
subclavian arteries. We report microscopic differences of the tunica media of
the brachiocephalic artery walls in pigeon of different ages in both sexes.
Groups of 6 female or male pigeons each, aged 20, 50 and 120 days were used.
Brachiocephalic artery samples were stained with haematoxylin
and eosin, and orcein for elastic layers. In male
pigeons the mean numbers of elastic layers of the tunica media in the right
side of brachiocephalic wall on day 20 was greater than at day 120 (P<0.05).
There was no difference in left arteries in female pigeons or between number of elastic layers of tunica media of the
brachiocephalic arteries in left side between sexes on any day. However in females the number wasgreater
compared with males in the right side on day 50 and both sides on day 120
(P<0.05). Vasa vasorum were present in
thein the tunica intima of brachiocephalic arteries.
Key words: Brachiocephalic artery, elastic layers,
vasa vasorum, pigeon, age, sex.
