A Rare Case of A Mass on the Neck that Changes its Dimensions When Weeping

İstanbul Medical Journal, 2017
When branchial clefts and pouches do not atrophy between 4 and 7 weeks of fetal life or when an anomalous or incomplete fusion occurs, congenital neck anomalies may develop.

Differential distribution of the Ca (2+) regulator Pcp4 in the branchial arches is regulated by Hoxa2.

PLoS ONE, 2013
Branchial arches are externally visible tissue bands in the head region of all vertebrate embryos. Although initially formed from similar components, each arch will give rise to different head and neck structures. In a screen designed to characterize the

Unraveling the transcriptional regulation of TWIST1 in limb development. [PDF]

PLoS Genetics, 2018
The transcription factor TWIST1 plays a vital role in mesoderm development, particularly in limb and craniofacial formation. Accordingly, haploinsufficiency of TWIST1 can cause limb and craniofacial malformations as part of Saethre-Chotzen syndrome ...

Accessory auricles affecting the tragus and cheek occurring with cervical chondrocutaneous branchial remnants: A case report

JPRAS Open, 2015
Accessory auricles are protruding skin lesions commonly affecting the tragus, preauricular region, and cheeks. Similar lesions, termed cervical chrondrocutaneous branchial remnants, may occur in the neck; however, they are thought to have a differing ...

Nkx2.6 expression is transiently and specifically restricted to the branchial region of pharyngeal-stage mouse embryos

Mechanisms of Development, 1997
The Nkx2.6 gene belongs to the NK superfamily of homeobox genes (Harvey, 1996). We report here the expression pattern of the murine Nkx2.6 gene during early mouse development, which is unique among the NK family of homeobox genes in that its expression is restricted to the very narrow development period between stages E8.5 and E10.5 of embryogenesis ...

Branchial cleft cyst - A case report with review of literature

Journal of Orofacial Sciences, 2014
Branchial cleft cysts are the most common congenital neck masses. The other name for Branchial cleft cyst is Benign cervical lymphoepithelial cyst, which occurs on the lateral aspect of the neck.

The occipital lateral plate mesoderm is a novel source for vertebrate neck musculature [PDF]

, 2010
In vertebrates, body musculature originates from somites, whereas head muscles originate from the cranial mesoderm. Neck muscles are located in the transition between these regions.
