This core might or might not contain two central microtubules (a 9 + 2
axoneme and a 9 + 0
axoneme, respectively).
Detail of elongated spermatids midpiece with many mitochondria (M) surrounding the
axoneme (A).
(1977) Observations of the structural components of flagellar
axonemes and central pair microtubules from rat sperm.
The flagellar region included an
axoneme, a pair of mitochondrial derivatives, a pair of triangular accessory bodies, and a puff-like corpuscle with electron-dense areas (Fig.
These transformed halves elongate and orient themselves on either side of the developing
axoneme. The derivatives become a major component of the mature sperm flagellum.
ROS increase DNA fragmentations (1), modify the cytoskeleton (15), affect the sperm
axoneme development (9) and inhibit sperm-oocyte fusion.

The basic structure of nonmotile, primary cilia of the renal tubular cells consists of 9 peripheral microtubular doublets that form the
axoneme, surrounded by a lipid bilayer that is continuous with the cell membrane.
During spermiogenesis, the distal centriole forms the
axoneme of the sperm tail and becomes a vestige, whilst the proximal remains close to its nucleus and is inherited by the embryo (8,9).
The distal centriole begins to develop the
axoneme (thread) that will become the tail (flagellum) of the sperm cell.
A novel microtubule-binding thioredoxin expressed predominantly in the cilia of lung airway epithelium and spermatid manchette and
axoneme. J.
