The rhombic lip can be divided into eight structural units based on rhombomeres 1-8 (r1-r8), which can be recognized at early stages of hindbrain development. [2] Producing granule cells and five brainstem nuclei, the rhombic lip plays an important role in developing a complex cerebellar neural system. [3] Rhombic lips
This area produces Purkinje cells and deep cerebellar nuclear neurons. These cells are the primary output neurons of the cerebellar cortex and cerebellum. The second germinal zone (cellular birthplace) is known as the rhombic lip, neurons then move by human embryonic week 27 to the external granular layer. This layer of cells—found on the ...
The Federative International Committee on Anatomical Terminology (FICAT), which is a subcommittee of the International Federation of Associations of Anatomists (IFAA), officially recognized the “unipolar brush cell” as a new cell type of the cerebellar cortex in 2008.
The granule cells, produced by the rhombic lip, are found in the granule cell layer of the cerebellar cortex. They are small and numerous. They are small and numerous. They are characterized by a very small soma and several short dendrites which terminate with claw-shaped endings.
WNT tumors originate from the lower rhombic lip of the brainstem, while SHH tumors originate from the external granular layer. [8] Currently, medulloblastomas are thought to arise from cerebellar stem cells that have been prevented from dividing and differentiating into their normal cell types. This accounts for the histologic variants seen on ...
A key group of Arab nations have said they “firmly” reject any efforts to resettle or evict Palestinians from Gaza, after US President Donald Trump said he wanted to “clean out” the ...

The anterior inferior cerebellar artery (AICA) is the principal vessel of the cerebellopontine angle. It also contains two cranial nerves – the vestibulocochlear nerve and the facial nerve; the cerebellar flocculus and the lateral recess of the fourth ventricle. [citation needed]
