Arrestins shuttle between cell nucleus and cytoplasm. Somatostatin is produced by neuroendocrine neurons of the ventromedial nucleus of the hypothalamus. These clusters appear in numerous and distinct parts of the cell nucleus and cytoplasm. The dorsal striatum consists of the caudate nucleus and the putamen. Inclusion bodies have been found in both the cell nucleus and cytoplasm. A hydrogen atom consists of an electron orbiting its nucleus. Protons and neutrons are baryons, joined by gluons to form the atomic nucleus. Osmotic pressure is detected by osmoreceptors in the median preoptic nucleus in the hypothalamus. These are all large linear DNA molecules contained within the cell nucleus. Neutrons are also capable of causing fission in an incident nucleus. It is associated with lesions in the left caudate nucleus. Its projecting pathways include the medial septal nucleus and supramammillary nucleus. Most alleles are located in chromosomes in the cell nucleus. Nuclear potential energy is the potential energy of the particles inside an atomic nucleus. Most input comes from collaterals of fibers passing through the thalamic reticular nucleus.
