axial filament

A filament forming the central axis of the flagellum of a spermatozoon.

intermediate filament

Abbreviation: IF
Slender proteins found in all eukaryotic cells, measuring about 8 to 12 nm in diameter. Intermediate filaments are composed of proteins including desmin, keratins, lamins, and vimentin and together with microtubules and microfilaments form the cytoskeleton. Some malignant cells can be identified by the specific proteins in their intermediate filaments.

thick filaments

Myosin, seen microscopically.

thin filaments

Actin, seen microscopically.

Ratio of thin filament to the thick filament is more than 1:10 and the mitochondrial area is approximately 25%.
The differences between ungrazed succession within cages and moderately grazed succession inside damselfish territories were due to, first, reciprocal variation in the abundances of green/brown filaments [ILLUSTRATION FOR FIGURE 5A OMITTED] and red filaments [ILLUSTRATION FOR FIGURE 5B OMITTED], and second, the near absence of thick filaments and blades inside territories [ILLUSTRATION FOR FIGURE 5C OMITTED].
6A corroborates the pattern that ungrazed succession within cages proceeded in three stages: early domination by green and brown filaments to midsuccessional dominance by red filaments to late domination by thick filaments and blades (cf.
Inside damselfish territories, the reef samples supported significantly less early successional green and brown filaments and more late successional thick filaments and blades than the settling plates.
