What's the difference between myotome and myotomy?
Myotome
Definition:
(n.) A muscular segment; one of the zones into which the muscles of the trunk, especially in fishes, are divided; a myocomma.
(n.) One of the embryonic muscular segments arising from the protovertebrae; also, one of the protovertebrae themselves.
(n.) The muscular system of one metamere of an articulate.

(19) In the two species, coexpression of alpha-sr and alpha-sm actins has been observed in cardiomyoblasts, myotomal myoblasts and myotubes.
(20) In the mouse, BCK transcripts are expressed in myotomes at 8.5 days post coitum (p.c.
Myotomy
Definition:
(n.) The dissection, or that part of anatomy which treats of the dissection, of muscles.
Example Sentences:
(1) Fourteen patients were examined one to four years after cricopharyngeal myotomy that had been carried out because of dysfunction of the pharyngo-esophageal sphincter.
(2) To improve the slightly disappointing voice rehabilitation results of the myotomized laryngectomees, a modified myotomy is proposed.
(3) In addition, we performed cricopharyngeal myotomy to prevent postoperative deglutition disorders.
(4) Combined medical treatment with amiodarone and diltiazem proved to be an effective alternative to surgical myotomy of the bridge.
(5) Although the operative technique for longitudinal ileal myotomy has the benefit of simplicity compared with construction of an ileal reservoir, the latter techniques, which have been used clinically on an extensive basis, are more likely to produce a consistent distension that is suitable for fecal storage.
(6) This finding is of relevance to the controversy surrounding cricopharyngeal myotomy in combination with pouch excision.
(7) Nineteen cases with major resections of the head and neck were treated with laryngeal suspension and cricopharyngeal myotomy in an attempt to allow swallowing function postoperatively and avoid a total laryngectomy.
(8) One of the myotomy wounds was filled with yellow-green material that extended from the base of the tail along the ventrolateral aspect of the rectum and into the peritoneal cavity.
(9) The authors found that having an endoscope in the esophagus during the operation facilitated exposure and was vital to determine the appropriate length of the myotomy.
(10) The procedure used restricted the myotomy to the diseased portion of the esophagus, as demonstrated manometrically.
(11) In one case there was, however, marked dyskinesia, requiring further myotomy.
(12) Three infants born with esophageal atresia that was repaired by end-to-end anastomosis combined with a circular myotomy on the upper segment are reported.
(13) Usually, a repeat myotomy was performed via an abdominal approach if the initial Heller's operation proved a failure, or via a thoracic approach if extensive motor disorders were discovered at manometry.
(14) Treatment, which may be simple excision or myotomy, does not correct the basic motor abnormality that is often associated with the diverticulum.
(15) The importance of the inferior myotomy for speech restoration in total laryngectomized patients following not only primary techniques (speech restoration by tracheo-esophageal puncture during total laryngectomy) but also secondary punctures, is well documented.
(16) The authors tested echocardiography as a method of guiding myotomy, and observed its clinical usefulness as a safe surgical procedure for IHSS.
