The regular disposition of attached cross bridges is visible in many areas.  Most images of this group show fractures through the outer membrane of mitochondria and SR\/T tubules of dyads nestled in long grooves of the mitochondrial surface.  All leaflets of the membranes appear in the images.  \n\nReferences for the image: \nLoesser, K.E. and Franzini-Armstrong, C.

The muscle was gently homogenized in a waring blender in 0.9% NaCl. The fibrils were deposited on glass and sequentially fixed in 0.1% glutaraldehyde in 0.1 M cacodylate buffer, rinsed in 100 mM ammonium acetate, treated with 1% uranyl acetate for 30 seconds, rinsed in 40% methanol and frozen in liquid nitrogen. The fibrils were freeze dried at -90 C for 30 minutes and rotary shadowed with platinum either at 25C or 45C in a Balzer's 400 freeze fracture. The glass was dissolved in hydrofluoric acid and the replicas were mounted on copper grids and examined in a Philips 410 Microscope."},"DATAQUALIFICATION":{"free_text":"RAW;spatialmeasurements"},"TERMSANDCONDITIONS":{"free_text":"public_domain"},"IMAGINGMODE":{"onto_name":"transmission electron microscopy (TEM)","onto_id":"FBbi:00000258"},"DIMENSION":[{"Space":{"Image_size":2495,"axis":"X"}},{"Space":{"Image_size":3298,"axis":"Y"}}],"NCBIORGANISMALCLASSIFICATION":{"free_text":"damselfly"},"PREPARATION":[{"onto_name":"glutaraldehyde fixed tissue","onto_id":"FBbi:00000011"},{"onto_name":"freeze_fracture\/freeze_etch","onto_id":"FBbi:00000419"}],"VISUALIZATIONMETHODS":{"onto_name":"shadowing and plating","onto_id":"FBbi:00000398"},"CELLTYPE":{"onto_name":"flight muscle cell","onto_id":"CL:0000196"}}},"Citation":{"Title":"Clara Franzini-Armstrong (2011) CIL:36088, damselfly, flight muscle cell.
