		Rostral to the midbrain lies the prosencephalon and caudally the rhombencephalon, the latter can be divided into 4 segments or pro-rhombomeres; A, B,C and D. B underlies the otic placode, and D lies medial to the occipital somites and comprises the hypoglossal region of the hindbrain.
		Medial to fibres of the mesencephalic tract of V, in the basal region of the isthmic segment and Rh1, elongated cells lie at boundary between the intermediate and ventricular layers.
		This decussation is known as the decussation of medial leminisci and fibres continue in the medial lemniscus to the ventral posterior thalamus.

		Das Rhombencephalon (Rautenhirn) ist der hinterste Abschnitt des Gehirns und stellt die Verbindung mit dem RÃ¼ckenmark her.
		Der Ã¼bergeordnete Begriff "Rhombencephalon" erklÃ¤rt sich aus der embryonalen Entstehung des Gehirns.
		Dann entwickelt sich durch unterschiedliches Wachstum zunÃ¤chst ein Zweiblasenstadium, das spÃ¤tere Prosencephalon und eben das Rhombencephalon.

	Rhombencephalon - Wikipedia, the free encyclopedia
		The rhombencephalon is a developmental categorization of portions of the central nervous system.
		The rhombencephalon can be subdivided in a variable number of transversal swellings called rhombomeres.
		In the human embryo we can distinguish eight rhombomeres, from caudal to rostral: Rh7 - Rh1 and the isthmus (the most rostral rhombomere).

		The walls of the mesencephalon thicken, and the neurocoel becomes a relatively narrow passageway comparable to the central canal of the spinal cord.
		The portion of the rhombencephalon adjacent to the mesencephalon forms the metencephalon.
		The portion of the rhombencephalon closer to the spinal cord forms the myelencephalon, which will become the medulla oblongata.

		This is the first step in the transformation of the periblastic-ectodermal extra-embryonic membranes into the definitive inner pericardial amnion and outer pericardial serosa, each a somatopleural membrane.
		The mesencephalon is widened, and the rhombencephalon less so.
		The rhombencephalon, in the region of the cranial placodes, possesses a thin roof, i.e., the characteristic tela choroidea of the myelencephalon (fig.

	Accumulation of Waterborne Mercury(II) in Specific Areas of Fish Brain
		Since labeling of the optic nerve and tectum appears to be lower than that of rhombencephalon and cerebellum (Table 2), this difference between the two fish species is probably related to the lower concentration of radioactive metal to which brown trout was exposed.
		In trout, the primary motor neurons that may be involved are those of Vth to Xth cranial motor nerves, which originate from nuclei located in the rhombencephalon, and the spinal motor neurons cell bodies located in the ventral horns of spinal cord (19).
		In the case of rhombencephalon and medulla of corpus cerebelli, it is not possible to assess the contribution of axonal transport in motor nerve fibers to the labeling of these brain structures with the present set of data, since they both receive primary sensory and motor nerve fibers.

		To visualize the pattern of PCD, the photo multiplier tube (PMT) value was increased relative to the ethanol-exposed specimen.
		Eight individual optical sections were selected to illustrate PCD within the rhombencephalon (arrowheads) and closing anterior neuropore (arrow).
		Individual optical sections reveal excessive apoptosis in the frontonasal prominence, trigeminal ganglion, first branchial arch, discrete regions of the rhombencephalon (arrowheads), otic pit (arrow), the epibranchial placodes for cranial nerves IX and X (open arrow), and the septum transversum (*).

		The anterior prosencephalon is associated with the olfactory sense, the middle mesencephalon with vision, and the posterior rhombencephalon with detection of balance, acceleration, and equilibrium.
		The inner ear (otic vesicle) is the sense organ associated with the rhombencephalon and it can be seen as a large clear oval beside the anterior rhombencephalon.
		Above it is the flat nerve cord (or rhombencephalon depending on the level of section).

		No, the answer is D. The secondary vesicles formed from the forebrain are the telencephalon (precursor of the cerebral hemispheres) and the diencephalon (which forms the adult epithalamus, hypothalamus, and thalamus).
		No, the answer is E. The rhombencephalon forms 2 secondary vesicles, the myelencephalon and the metencephalon.
		This flexure is formed by diffe- rential growth in the rhombencephalon.

		Immunohistochemical localization of nerve growth factor, glial fibrillary acidic protein and ciliary neurotrophic factor in mesencephalon, rhombencephalon, and spinal cord of developing mongolian gerbil.
		The distribution of the nerve growth factor (NGF), the glial fibrillary acidic protein (GFAP) and the ciliary neurotrohic factor (CNTF) was performed in coronal sections of the mesencephalon, rhombencephalon and spinal cord in the developing Mongolian gerbils.
		Generally, NGF specifically recognizes neurons with the NGF receptor, whereas GFAP does the glia, and CNTF does the motor neurons.

	Local increase level of chondroitin sulfate induces changes in the rhombencephalic neural crest migration (Site not responding. Last check: 2007-10-21)
		ABSTRACT Numerous studies suggest that chondroitin sulfate proteoglycan (CSPG) inhibits neural crest cells (NCC) migration at the trunk level; however, its action on the cephalic neural crest is not clear.
		Results obtained for both experimental groups were similar; immunoreactivity with HNK-1 antibody revealed that NCC did not migrate, remaining near the rhombencephalon dorsal wall; in addition, several NCC did not separate from the neural fold, becoming invaginated towards the rhombencephalon cavity.
		Our findings indicate that an increase in CS free chains in cephalic neural crest migratory routes not only disrupts their migration, but also impedes delamination and detachment of the rhombencephalic neuroepithelium NCC.

		The rhombencephalon is the embryonic hindbrain rudiment, from which the cerebellum buds off (as the metencephalon) and differentiates.
		In RHS the central part of the cerbellum (vermis) fails to develop and the two cerebellar hemispheres fuse into a single mass: Thus 'synapsis', which implies fusion.
		Recognition of this anomaly in the living patient may be useful in further understanding the clinical significance of segmentation of the rhombencephalon.
