What's the difference between neuromere and neurotome?
Neuromere
Definition:
(n.) A metameric segment of the cerebro-spinal nervous system.
Example Sentences:
(1) However, the pattern in the central nervous system (CNS) and mesoderm is further restricted; the major expression located in the labial neuromere of the CNS and the mesoderm of the first thoracic segment.
(2) Arborizations of motoneurons are not restricted to their neuromere of origin but invade adjacent neuromeres, resulting in regions of dendritic overlap of motoneurons to different muscles.
(3) Six of these neurons have cell bodies in the thoracic neuromeres and 12 in the fused abdominal neuromeres.
(4) The midline glia then defasciculates as neuroblasts begin to aggregate into neuromeres.
(5) Taken together, our results suggest that Wnt-3 and Dlx-1 provide positional information for the regional specification of neuromeres in the forebrain.
(6) The case is characterized by successful counteracting the main clinical manifestations of Raynaud's phenomenon by the local metameric application of cerebrolysin (neuromeric, scleromeric puncturing) employed by the authors for the first time for the disease treatment.
(7) The most protruding zone in the preotic sulcus formed the eighth neuromere and was located adjacent to the first branchial arch and the trigeminal ganglion.
(8) Type 1: Unilateral interneurons in the metathoracic neuromere; soma in anterior position; arborization dorsal, in anterolateral, posterolateral, and midline regions.
(9) Tactile receptors have smaller arbors, which are located in a ventral region of the thoracic neuromere.
(10) Processes of leucokinin I immunoreactive (LKIR) neurons were distributed throughout the nervous system, but immunoreactive cell bodies were not found in all neuromeres.
(11) The most protruding zone in the otic sulcus also formed the 11th neuromere and was located adjacent to the second branchial arch.
(12) In the wandering spider Cupiennius salei, the functional neuroanatomy of leg mechanosensory receptor neurons and interneurons associated with a single leg neuromere was investigated by combined intracellular recording and Lucifer yellow ionophoresis.
(13) Type 2: Unilateral interneurons in the metathoracic neuromere; neurite with characteristic hairpin bend; soma in lateral position; arborization through the lateral neuropil region.
(14) Early neuroblasts appear as separate, distinct groups within specific matrix territories at the center of the transverse neuromeric segments.
(15) Examination of scanning electron micrographs of 4-, 8-, 12- and 16-somite-stage embryos has shown that the neuromeres develop in a strictly ordered pattern but the sequence is not ordered in either a rostrocaudal or caudorostral direction.
(16) This nucleus, with a moniliform aspect, extends into the first two cervical neuromeres and enters the bulb, where it is continuous with the alpha subdivision of the hypoglossal nucleus.
(17) Based on these observations a description is given of the neuromeres present within the prosencephalon and of the termination of the sulcus limitans.
(18) The type 1 SE cells seem to possess neuronal functions, as deduced from morphological similarities to their counterparts in adults and the specialized distribution closely related to neuromeres.
(19) Golgi impregnation and intracellular dye filling show that local interneurons originate in ventral sensory neuropiles of leg neuromeres and ascend dorsally to terminate amongst dendrites of motor neurons.
(20) Around embryonic day 11.5, Wnt-3 expression becomes restricted to one of the neuromeres of the diencephalon, the dorsal thalamus.
Neurotome
Definition:
(n.) An instrument for cutting or dissecting nerves.
(n.) A neuromere.
Example Sentences:
(1) Interpretation of multiple malformation syndromes is proposed on the basis of neurotomes, or embryonic developmental fields with common regional innervation.
(2) Analysis of radioactively labeled proteins was carried out on microsamples of myelin-free axons isolated from neurotomized and normal hypoglossal nerves of the rabbit after in vitro incubation with [3H]leucine.
(3) Congenital abnormalities within the same or adjacent neurotomes would explain the distribution of defects in thalidomide embryopathy and morphologically similar multiple malformation syndromes.
(4) Skeletal and internal structures are shown to be linked anatomically through segmental levels of innervation, or "neurotomes", and are related embryologically to the neural crest.
