Mouse Spermatozoa EM and Diagram

The Spermatozoon: the spermatozoon is made up of two main regions, the head and the tail. The anterior portion of the head is covered by the acrosomal cap and the head is joined to the tail by the connecting piece. The tail is divided into three regions: the midpiece; principal piece; and the end-piece.

The electron micrographs showing cross-sections (not to scale) of each region highlights the main components of the tail structure: the axoneme; outer dense fibers (ODF); and the mitochondrial sheath (midpiece) and fibrous sheath (FS) (principal piece). The end-piece consists solely of the axoneme and plasma membrane.
