The extraocular muscles of four male subjects were dissected out and stained with several silver impregnation methods. The results obtained showed the presence of nerve endings that surround muscle fibers and correspond to the classification of simple spiral nerve endings by Daniel (1946). However they were found to differ in size from this description. They were distributed throughout the entire body of the muscles, although they appeared to be more abundant in the proximal third. Most of these endings encircled between two and four times the muscles fibers. The nerve fiber forming the spirals were surrounded by a capsule of connective tissue which appears to keep the fibers attached to the muscles. The fact that proprioceptors may adopt different morphological shapes suggests that proprioception may be conformed of different components, one of which may be mediated by simple spiral nerve endings.</p>","PeriodicalId":75637,"journal":{"name":"Bulletin de l'Association des anatomistes","volume":"78 241","pages":"37-40"},"PeriodicalIF":0.0,"publicationDate":"1994-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19079859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As early as day 14 after implantation osteogenesis so that resorption of the newly formed bone and of the biomaterial, were observed at the surface of the ceramic, inside the macropores. Osteoblasts were clearly visible and well differentiated with abundant rough endoplasmic reticulum and large Golgi zone. The resorption processes were associated with 2 types of multinucleated cells. Based on ultrastructural observations (cellular characteristics and measurement of the microporosity) it appears that incompletely differentiated osteoclast was the major cell responsible of the biodegradation of the ceramic.
