For their accurate regional diagnoses, understanding the anatomy of the spatial relationship between muscular fibers and tendinous structures is important because their interfaces are susceptible sites to muscle strains.

The anterior surface had three aponeurotic origin tendons, lateral origin tendon (LOT), medial origin tendon (MOT), and tendinous arch, which were arranged along the soleus margins. The anterior bipennate muscle portion (ABP), surrounded by the three origin structures, terminated as the sagittal insertion tendon (SIT), which continued inferiorly to PIT. The posterior main muscle portion behind LOT and MOT was separated into lateral and medial portions by the SIT. The soleus thus possessed a broad musculotendinous junction. Furthermore, ABP exhibited wide structural diversity in shape and size: in extreme cases, it was duplicated or absent.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Systematic anatomical descriptions of the soleus will be useful for accurate regional diagnosis of its strains with magnetic resonance imaging and ultrasonography.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ca.23667","type":"journal-article","created":{"date-parts":[[2020,8,12]],"date-time":"2020-08-12T02:36:56Z","timestamp":1597199816000},"page":"991-1001","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Anatomical study of the soleus: Application to improved imaging diagnoses"],"prefix":"10.1002","volume":"34","author":[{"given":"Naoaki","family":"Kimura","sequence":"first","affiliation":[{"name":"Department of Anatomy and Life Structure Juntendo University Graduate School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kota","family":"Kato","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Life Structure Juntendo University Graduate School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidaka","family":"Anetai","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Life Structure Juntendo University Graduate School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuto","family":"Kawasaki","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Life Structure Juntendo University Graduate School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takayuki","family":"Miyaki","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Life Structure Juntendo University Graduate School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Kudoh","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Life Structure Juntendo University Graduate School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuo","family":"Sakai","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Life Structure Juntendo University Graduate School of Medicine  Tokyo Japan"},{"name":"Department of Physical Therapy, Faculty of Health Science Juntendo University  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6590-7912","authenticated-orcid":false,"given":"Koichiro","family":"Ichimura","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Life Structure Juntendo University Graduate School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,9,2]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/ca.10112"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-012-1513-3"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-014-1856-z"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/aja.1000060108"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.7717\/peerj.4610"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12178-009-9045-8"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0223531"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004210050677"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2014.08.002"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/ca.20544"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.29.4.277"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.00596.2003"},{"key":"e_1_2_7_14_1","first-page":"1","article-title":"Der Musculus triceps surae in der Primatenreihe","volume":"47","author":"Frey H.","year":"1913","journal-title":"Morphologisches Jahrbuch"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(90)90373-B"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.1100100623"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1177\/036354659602406S02"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2010.06.025"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/ca.21188"},{"issue":"3","key":"e_1_2_7_20_1","first-page":"324","article-title":"The comparative anatomy of the muscles and nervesof the superior and inferior extreamities of the anthropoid apes.
