CIL:11955
NCBI Organism Classification
none specified
Biological Process
ciliary or flagellar motility
Cellular Component
flagella
Movie of portion of a hypermastigote symbiont from the hindgut of a wood eating cockroach. The rootlets and flagella are birefringent and the beating flagella are clearly seen with the polarizing micr...

Hypermastigote protozoan
Biological Process
motlity
Cellular Component
none specified
The movie shows the wave-like effect of compensated birefringence caused by rotating spirochetes attached to the surface of a hypermastigote protozoan. The image was obtained using a rectified polariz...

Chrysochraon japonicas
Biological Process
meiosis
Cellular Component
spindle
The time-lapse movie made in 1974 shows meiosis in spermatocytes of Chrysochraon japonicas (grasshopper) as seen with the polarizing microscope. The principal birefringent components are the spindle m...

Arbacia punctulata
Biological Process
fertilization
Cellular Component
none specified
The movie shows two sequences that begin with an unfertilized Arbacia (sea urchin) egg in which the contents have been stratified using the centrifuge polarizing microscope (CPM) developed by S. Inoue...

Chaetopterus sp. 1 Woods Hole MA
Biological Process
meiosis
Cellular Component
spindle
This is one of 4 grouped time lapse movies (CIL 11958-11962) revealing the responses of a meiotic oocyte spindle to various forms of micromanipulation by a glass microneedle. The needle is inserted, ...

Halistaura cellularia
Biological Process
mitosis
Cellular Component
spindle
Time lapse movie showing mitosis and cleavage in fertilized eggs of the jellyfish Halistaura cellularia. The use of polarizing microscopy reveals the mitotic spindles, which are seen in bright or dar...

NCBI Organism Classification
uncultured Pyrsonympha sp.
Biological Process
motility
Cellular Component
axostyle
The movie shows the rhythmic movement of the termite flagellate Pyrsonympha, a symbiont that lives in the hindgut. The motile structure is a complex of ~2,000 aligned microtubules, the axostyle which ...

Spirocodon saltatrix
Biological Process
mitosis
Cellular Component
spindle
Dividing egg of the jellyfish (Spirocodon saltatrix showing birefringent spindles. The arrow indicates the direction of the compensator slow axis. AS the cell is rotated 90 degrees with respect to the...

Lytechinus
Biological Process
mitosis
Cellular Component
none specified
The time-lapse movie shows early development in the Lytechinus (sea urchin) embryo. Polarizing microscopy highlights the mitotic spindles which may show bright or dark contrast according to their orie...
