✦ Synopsis
Epididymal spermatozoa from two species of vole demonstrate cytoskeletal structures closely associated with the plasma membrane. Microtubule-like elements (20--24 nm in diameter) form a parallel sheath radiating from the posterior ring to the inferior acrosomal margin just beneath the plasma membrane. Fine filaments (5-8 nm in diameter) are associated with the cell surface, especially in I he region of the concave curvature of the acrosomal hook. Both of these elements may aid in stabilizing these respective areas and it is suggested that microtubule-like and filamentous structures may serve important cytoskeletal roles in the mature sperm head.
