Schematic Representation of a Centrosome and a Spindle Pole Body
The centrosome is about 1 μm in diameter, and the SPB is about 100 nm in diameter. Microtubules, shown as black lines, are nucleated from the pericentriolar material of centrosomes (A) and from the inner and outer plaques of the SPB (B). The centrosome is often associated with, but physically separate from, the nucleus, whereas the central plaque of the SPB is embedded in the nuclear envelope (ne). The half-bridge structure of the SPB is the site of initiation of a new SPB.
