Support cells extend from the basal lamina to the lumen of the testis and are laterally connected to the germinal epithelium. Germ cells present intercellular bridges and flagella since the spermatogonial stage. While spermatogonia and spermatocytes appear connected to support cells by desmosome\u2010like junctions, elongated spermatids are held at the acrosomal region by support cell finger\u2010like processes. During spermiogenesis, the acrosomal vesicle differentiates from a golgian saccule and then migrates to the nuclear apex. A microtubular manchette arising from centrioles surrounds the acrosomal vesicle, the nucleus, and the mitochondria at the time these three organelles start their elongation, disappearing after that. The mature spermatozoon of S. plana<\/jats:italic> lacks a distinct midpiece because the mitochondria extend from the region of the pericentriolar complex along the nucleus anteriorly for approximately 1.4 \u03bcm. The features of this bivalve type of modified spermatozoon are compared with those of other animal groups having similar modifications.<\/jats:p>","DOI":"10.1002\/mrd.1120240406","type":"journal-article","created":{"date-parts":[[2005,2,25]],"date-time":"2005-02-25T12:26:47Z","timestamp":1109334407000},"page":"393-401","source":"Crossref","is-referenced-by-count":42,"title":["Ultrastuctural and cytochemical study of spermatogenesis in Scrobicularia plana<\/i> (Mollusca, Bivalvia)"],"prefix":"10.1002","volume":"24","author":[{"given":"M\u00e1rio","family":"Sousa","sequence":"first","affiliation":[]},{"given":"Laura","family":"Corral","sequence":"additional","affiliation":[]},{"given":"Carlos","family":"Azevedo","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2005,2,18]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"47","article-title":"The fine structure of the spermatozoon of Patella lusitanica (Gastropoda: Prosobranchia), with special reference to acrosome formation","volume":"13","author":"Azevedo C","year":"1981","journal-title":"J Submicrosc Cytol"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmor.1051860110"},{"key":"e_1_2_1_4_1","first-page":"609","article-title":"Ultrastructure of the spermatozoon in Gibulla umbilicalis (Gastropoda, Prosobranchia), with special reference to acrosomal formation","volume":"17","author":"Azevedo C","year":"1985","journal-title":"J Submicrosc Cytol"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/mrd.1120150103"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00213936"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/mrd.1120070103"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.2307\/3225187"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmor.1051700303"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/mrd.1120070302"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1080\/01688170.1988.10510362"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/mrd.1120150204"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmor.1051950207"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5320(77)90013-2"},{"key":"e_1_2_1_15_1","first-page":"411","article-title":"Organizing process of the temporary\u2010acrosome in the spermatogenesis of the bivalve Lyonsia ventricosa","volume":"10","author":"Kubo M","year":"1978","journal-title":"J Submicrosc Cytol"},{"key":"e_1_2_1_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5320(69)80042-0"},{"key":"e_1_2_1_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5320(67)80113-8"},{"key":"e_1_2_1_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00312147"},{"key":"e_1_2_1_19_1","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.79.1.45"},{"key":"e_1_2_1_20_1","doi-asserted-by":"publisher","DOI":"10.1071\/ZO9740001"},{"key":"e_1_2_1_21_1","first-page":"573","article-title":"An ultrastructural study of the spermatozoa of the polychaetes Eurythoe complanata (Amphinomidae), Clymenella sp. and Micromaldane sp.
