- microvesicle
An extracellular vesicle released from the plasma membrane and ranging in size from about 100 nm to 1000 nm.
- actin tubule
A cellular structure, approximately 13 nm in diameter, consisting of three actin filaments bundled together.
- complex laminated body
A cytoplasmic inclusion body found in some lateral geniculate neurons and composed of sheets of tubules (25 nm in diameter) separated by dense material (about 75 nm wide), which together with the tubules whorl give a structure resembling a fingerprint.
- pilus
A proteinaceous hair-like appendage on the surface of bacteria ranging from 2-8 nm in diameter.
- ciliary rootlet
A cytoskeleton-like structure, originating from the basal body at the proximal end of a cilium, and extending proximally toward the cell nucleus. Rootlets are typically 80-100 nm in diameter and contain cross striae distributed at regular intervals of approximately 55-70 nm.
