A Moving Kinesin Motor Protein The two heads of the kinesin dimer work in a coordinated manner to move processively along the track. The coiled coil (gray) extends towards the top and leads up to the ...

Zebrafish embryo at 75% epiboly. The view is from the animal pole. The focal plane is deep within the blastoderm. The focal plane changes as the embryo rolls during the sequence. The fluorescent lipid...

Platinum replica depicting the cytoskeletal organization of dendritic spines in extracted 14 DIV neurons. Mushroom spines associate with dendrites at the base (bottom) and with axons by the head (top)...

Scanning electron micrograph showing tentacles on the head of a Hydra viridis. Epithelial cells located at the base of the tentacle are in a flat, contracted state. Cell distal to the head of the H. v...

Scanning EM of the head folds. Specimens were chemically fixed critically point dried, and sputter coated with gold/palladium. This image is part of a series taken by Bryan Crawford while he was at ...

This study on the zebrafish optic tectum is a series of four images with magnifications ranging from the SEM block face overview to of the zebrafish head to high magnification (80,000X) showing optic ...
