WebApr 9, 2009 · The mesodermal cells at Hensen’s node in the chick are devoid of cilia. In addition, the Talpid chick mutant lacks primary cilia ( 6 ) but does not exhibit L/R asymmetry defects. Unlike in the mouse and rabbit, the chick node itself becomes morphologically asymmetric, with a marked tilt toward the left around the time the primitive streak ... WebCells residing within Hensen's node (the cranial end of the primitive streak) initially migrated mainly cranially, remaining on or near the midline, and then extended caudally along the midline as regression of Hensen's node occurred. Cells residing within the nodus posterior (the caudal end of the primitive streak) migrated caudally. Hensen's cells are a layer of tall cells arranged in the organ of Corti in the cochlea, which are part of the supporting cells lie on the outer hair cells (OHC). Their appearance are upper part wide with lower part narrow, column like cells. One significant morphologic feature of Hensen's cells is the lipid … See more Hensen's cells are one of the supporting cells found in the cochlea, and are located on the third row outer hair cells in the Organ of Corti. See more The shape of Hensen's cells are various in different position of cochlea, they appear as a single layer of cells in the basal coil while appear as cuboidal form in the apical surface.
