Taylor Allen: Still Looking at Worms--with New NSF Grant to Fund His Research on Muscle Function
(Main Story)

Microscopic Views of Muscle

The top microscopical image depicts the distribution of thick filaments in the dorsal muscle of an adult C. elegans worm (length about 1 mm). Each white stripe in the panel is composed of thousands of thick filaments packed together. The dorsal muscle is composed of two adjacent rows of muscle cells running from head to tail of the worm.

The lower panel, which was obtained by a different optical method from that used for the upper panel, depicts a single muscle cell (length about 0.1 mm): its striated appearance arises from the highly ordered, interdigitating arrays of thick and thin filaments. Skeletal and heart muscles from humans and other animals have a similar striated appearance--in fact, these are collectively called striated muscle.
