What's the difference between hemisection and mesial?
Hemisection
Definition:
(n.) A division along the mesial plane; also, one of the parts so divided.
Example Sentences:

(10) By contrast, animals undergoing spinal cord hemisection developed obvious motor deficits in the ipsilateral hindpaw in addition to the deficits in the forepaw.
(11) Since the hemisection of the spinal cord at T6 suppresses this reflex in the pinna of the same side, it must be concluded that the spinal pathway is ipsilateral.
(12) Thirteen percent (five of 37) of all Hoke percutaneous triple hemisection Achilles tendon lengthenings performed at a teaching hospital in a 4-year period were complicated by inadvertent Achilles tenotomy.
(13) The effects of the excitatory amino acid agonists kainate (KA), quisqualate (QUIS), and N-methyl-D-aspartate (NMDA) were studied in vitro on the hemisected frog spinal cord.

(15) (5) Transverse hemisection at the rostral border of the pons abolished the RJMs induced from the contralateral, but not ipsilateral, MRF.
(16) We describe the use of isolated hemisected mouse spinal cords for pathophysiological investigations and analyze the responses evoked and recorded with suction electrodes in spinal roots.
(17) In both hemisected and quadrisected spinal cords, reproducible depolarization responses were induced by low concentrations of the neurokinin-1-selective agonist substance P methylester (10 nM-1 microM) or of the neurokinin-3-selective agonist senktide (3-300 nM).
(18) Control injections were performed in two intact monkeys and in two other monkeys immediately after hemisection.
(19) In an additional group of eight neonatal operates, the spinal cord rostral to the spinal hemisections was transected at 1 month of age.
(20) The hemisection deficit also differs in character from that following optic nerve section or tectal lesion.
Mesial
Definition:
(a.) Middle; median; in, or in the region of, the mesial plane; internal; -- opposed to lateral.
Example Sentences:
(1) Thus, in approximately 80% of seizures, the onset of ictal EEG changes resided in the mesial temporal structures.
(2) Possible mesial root extrusion was found in 60.0% of the uprighted molars.
(3) The vertical distances were compared with measurements taken from periapical radiographs between the apex of each mesial root and the superior border of the mandibular canal prior to sectioning.
(4) Ablations of the entire dorsal convexity, and of the mesial and cingulate regions of the cortex, failed to interfere with the spindle bursts and recruiting responses, whereas ablations confined to the orbital cortex alone abolished completely these potentials in the cortex and thalamus.
(5) In both experimental systems the movement was derived largely from a mesial drift of the third molar, and its rate decreased with time.
(6) The mesial movement was achieved with rubber band pull.
(7) However, among 27 patients examined by means of intracranial EEG recordings, it was evident that a disgust expression occurred with oro-alimentary automatisms at the beginning of mesial temporal lobe seizures, whereas a happy one occurred without oro-alimentary automatisms at the beginning of lateral temporal lobe seizures.
(8) Alveolar bone resorption was measured on enlarged cephalographs (5.7 X) at a point mesial to the mandibular first molar.
(9) The "C" was open anteriorly and the lateral arm extended almost twice as far incisally as the mesial arm.
(10) Intra- and inter-hemispheric propagation of ictal discharges was analyzed with computer techniques in 10 patients with complex partial seizures of mesial temporal lobe origin in whom depth electrodes had been stereotaxically implanted.
(11) We measured local cerebral metabolic rates for glucose in mesial and lateral temporal structures and compared them with metabolic rates for analogous regions in 16 healthy normal volunteers and the contralateral hemisphere of the epileptic patients.
(12) The risk of resorption also will increase with a more mesial horizontal path of eruption.
(13) They can be summarized as: mesial shifting of the maxilla, dimensional increase of the mandibular body, ovoidal upper arch with a deeper palatal vault, tapering or trapezoidal lower arch.
(14) N140 and P190 (the "vertex potentials") are probably generated bilaterally in the frontal lobes, including orbito-frontal, lateral and mesial (supplementary motor area) cortex.
(15) Propagation of paroxysmal activity through the anterior ventral thalamic nuclei and cingulate gyri was observed in all cases with temporal or frontal mesial focus.
(16) These included torn or frayed menisci and those which were displaced, usually in a mesial direction.
(17) Future studies in non-human primates may reveal that ictal discharges which originate in the mesial temporal region propagate preferentially via brain-stem pathways to contralateral homologous regions.
(18) Electrode tips recording beta rhythms were found: (i) in motor areas 4 gamma and 6a beta, in a band extending from the postcruciate cortex to the walls of the presylvian sulcus, crossing the frontal pole (anterior beta focus); (ii) in the posterior parietal associative area 5a, along the divisions of the ansate sulcus, extending to the mesial aspect of the hemispheres (posterior beta focus).
(19) Finally polynomes of 4th degree were chosen to describe the anterior dental arch from 6 mesial to mesial 6 of the arcogram.
(20) The results suggested that effective distal and intrusive movements would be expected by bending the outer-bow downward, since this procedure would prevent the tooth from tipping mesially.
