Description

Pseudopods jut out from this polymorphonuclear leucocyte of the guinea pig to enable amoeboid motility. Organelles are initially excluded as the pseudopod first forms, but they flow in as the pseudopod enlarges. The continuous, multi-lobed nucleus appears in this field of view as two separate structures because of the thin section through the cell. Figure 45 from Chapter 2 (Specializations of the Free Surface) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A PDF copy of the accompanying chapter is available on the ASCB’s BioEDUCATE website.
