Sammanfattning

Beskrivning
English: Morphology of Mesenchytraeus solifugus (Oligochaeta: Enchytraeidae).
Explanations: cd – dorsal chaetae; cv – ventral chaetae; ce – brain; cu – cuticle; h – hypoderm; i – intestine; in – funnel; lc – cephalic lobe; ml – longitudinal muscles; mt – transversal muscles; ne – nephridium; nv – ventral ganglion chain; o – mouth; ph – pharynx; pn – nephridial pore; se – septum.
  1. Habitus. x9
  2. Brain and oesophageal ring; reconstucted from a series of horizontal sections. In front of the brain the cephalic lobe shows a thickened hypoderm, with pigmented sense cells. x130
  3. Sagittal section of the foremost part of the body (combined from a series of not perfectly sagittal sections), pc – cephalic pore, v – blood vessel. x130
  4. System of muscular bundles, which move the pharynx (m, ph); reconstruction; the outer wall of the body is supposed to be transparent. Of internal organs, the central nerve system and the intestines only are drawn. x100.
  5. Section of the intestinal wall in the fore part of the body, with the chloragogene cells there are branched pigmented cells, chl; ei – ciliated intestinal epithelium, s – blood lacunes. x380.
  6. Section of the epithelium of the pharynx; between the epithelial cells there are branched pigment cells. x380.
  7. Transversal section of the body wall. x380
  8. Section of the body wall in the clitellar segment; from a specimen approaching maturity. x360
  9. Horizontal section of the cephalic lobe: cs – sense cells. x380
  10. The four chaetae of a bundle in a posterior segment, isolated by means of caustic potash. x380
  11. Longitudinal vertical section of the 6th segment, showing the body cavity filled by unicellular glands gl. x250
  12. Longitudinal vertical section of the 10th segment, showing th cluster of granulated cells, x, and the large dark pigmented cells, pg, which lie around the bundles of chaetae. x250
  13. Longitudinal section through the ventral bundle of chaetae in a posterior segment. x250
  14. Three lymph cells in the coelome. x380
  15. The right nephridium of the 15th segment, with the neighbouring bundles of chaetae. Combined figure from two sections. x250
  16. Reconstucted sperm duct of the right side. p – pore, a – bulb (drawn as semi-transparent), in which the prostatic glands bb open; c – fusiform swelling of the duct; d – loop surrounded by the glands e; in – funnel. x130
  17. Reconstructed spermathecae as a transverse section (from a series of transverse section), prs – expernal pore; drs – duct; rs – cavity of the spermathecae, ars – its appendages. x130
  18. Anoplophrya sp? parasite in the intestine of Melanenchytraeus. x380
  19. Parasitic cysts from the intestine of Melanenchytraeus; a – entire cyst; b – longitudinal cut cyst, showing its content of nucleate clear globules
