TL;DR: This chapter provides information to understand the relationship between the bioactive molecules and the cell structures and to compare such biological events as the fine structure of the gametes between in vivo and in vitro conditions, and between human and other species.

TL;DR: It is suggested that these immunoreactive cells in the ventricle may differentiate, in situ, into the cells of the impulse-conducting system during the further development of the heart.

TL;DR: From this survey new schematic diagrams have been drawn emphasizing the pertinent venous anatomy at the proximal, distal interphalangeal joints and eponychial levels, and Suggestions are made for regions that are apt to have the largest vessels available for anastomosis.

TL;DR: Colloidal gold-immuno-electron microscopy of mouse spermatozoa has shown that the antigen is localized in the space between the outer and inner acrosomes membranes and on the acrosome membranes at the equatorial segment.

TL;DR: The distribution of intramembranous particles (IMPs) and membrane filipin-sterol complexes (FSC) was examined ultrastructurally in mouse spermatozoa from the male reproductive tract and ejaculates and may be summarized as follows.
