What's the difference between neurotome and neurotomy?
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.
Neurotomy
Definition:
(n.) The dissection, or anatomy, of the nervous system.
(n.) The division of a nerve, for the relief of neuralgia, or for other purposes.
Example Sentences:
(1) Selective extrinsic neurotomy of either compartment abolished all responses.
(2) Thirteen Rana pipiens underwent unilateral sciatic neurotomy and were sacrificed weekly as long as 46 days.
(3) This target phenomenon and the contraction artefacts could be inhibited in the tenotomized muscles by simultaneous neurotomy or immobilization of the muscle with a plaster cast.
(4) The neurotomy and the nerve graft were repaired on one side by microsurgical suture technique using 10-0 nylon suture.
(5) The results were effective, with a 1 to 13 year follow-up (5 on average), in 89% of 47 Selective Peripheral Neurotomies of the tibial nerve for spastic foot, in 92% of 53 Selective Posterior Rhizotomies for paraplegia and in 87% of 23 Selective Posterior Rhizotomies for hemiplegia.
(6) Brief hyperoxic tests induced transient decreases in tidal volume and increases in end-tidal CO2 pressure which were significantly larger at 40 degrees C than at 37 degrees C. These changes disappeared after bilateral carotid neurotomy.
(7) Effect of 1,25(OH)2(Me)2D3 on osteopenia in rats induced by ovariectomy and right sciatic neurotomy was higher than that of 1,25(OH)2D3.
(8) Various surgical therapeutic procedures have been described, including neurotomy of the glossopharyngeal nerve in the frontal neck, thermocoagulation of Andersch's ganglion, and para-pontine neurotomy (Dandy).
(9) In the animals with one of these neurotomies plus contralateral ovariectomy, the fertility increased to 100%.
(10) The effects of a 3-week treatment with the nonsteroidal "antiestrogen" tamoxifen were determined on cortical and trabecular bone mass of the tibiae of growing male rats that had undergone unilateral sciatic neurotomy (USN).
(11) The cases with ovarian neurotomy and contralateral ovariectomy exhibited a greater number of implantations in the uterine horn on the side of the neurotomy as compared with the control rats.
(12) This paper deals with the long term results of Selective Peripheral Neurotomies of the Tibial Nerve and Selective Posterior Rhizotomies in the Dorsal Root Entry Zone, in 123 patients with spastic disorders localized to the limbs.
(13) Major radioactive peaks in axonal endings of the proximal stump 18 h after neurotomy, identified by autoradiography of microelectrophoregrams, had apparent molecular weights of 52,000d, 41,000d and 18,000d.
(14) The effect of anhydrous glycerol on both spontaneous firing from the neuroma and impulse propagation within the nerve was examined in 11 rats that had undergone saphenous neurotomy 7 days previously.
(15) Nerve sections were performed by two methods: 1) bilateral SLN-s, RLN-s and cervical vagal neurotomy (horizontal method); 2) right-sided neurotomies of SLN, RLN and vagus followed by left-sided neurotomies of these nerves (vertical method).
(16) In the sciatic neurotomy group of rats, neither trabecular number nor width significantly changed at 12 weeks after surgery.
(17) To investigate the effects of trigeminal denervation on the corneal epithelium, left postganglionic trigeminal neurotomy via intracranial approach was performed in 22 rabbits.
(18) All subjects underwent vestibular neurotomy via the retro-sigmoid approach.
(19) These results suggest that following pancreatic neurotomy, the potential for pancreatic regeneration continues over a longer period after major pancreatectomy.
(20) Bone atrophy induced by immobilization through sciatic and femoral neurotomy and that induced by isograft transplantation were thus shown to differ.
