| Summary: | The studies aimed to describe the nervous formations from the base of the cranium
in the hen and domestic duck. These clarifications are necessary in order to disclose
some unknown facts regarding this region in the poultry species used preponderantly
in laboratory studies of the aviary flu.
The vegetative connections from the base of the skull have been studied on 10
poultry specimens, 5 hens and 5 ducks. The animals have been euthanatized using
chloroform and a special dye has been injected through the heart in order to achieve
a better differentiation of the nervous formations. Dissection was performed under a
magnifying glass using instruments adequate to highly fine dissections. Photos and
sketches of the dissected pieces have been taken. Nomina Anatomica (2003) was
used to describe the observed formations.The studies showed that the cranial
cervical ganglia around which is the sub-basal nervous tissue, is located on the
border of the occipital hole, at the basis of the temporal pyramid, much deeper than
in mammalians; it is better developed in the duck (3-4 mm) than in the hen (1-2 mm);
the cranial cervical ganglia has the shape of a globe in gallinaceans and it is long in
shape in the ducks. A multitude of connecting branches were observed around the
lymph node, linking it to the vague nerve, to the hypoglossal nerve, to the glossopharyngeal nerve and to the transversal paravertebral chain which is specific to
poultry; an obvious branch detaches from the cranial pole, which is the sub-basal
connective, while the cervical connective detaches from the caudal pole, connecting
it to the cervical-thoracic lymph node. |
