A bundle of microtubules and associated proteins that makes up the core of a cilium or flagellum, consisting of nine pairs of microtubules arranged around two single microtubules.

The localization of RPGRIP1L to the ciliary axoneme, basal bodies, and centrosome or cytoplasm suggested a shuttling of RPGRIP1L between these different subcellular compartments.
Microscopic analysis revealed an absence of one of the microtubule doublets in three of the outer doublets of the axoneme, thereby establishing a diagnosis of isolated ciliary dysfunction.
The tail of the sperm is prepared by mitochondria, outer dense fiber (ODF) and axoneme. The positive results observed in the tail of sperm showed that there is a relationship between the CDC25A protein and the motility of the sperm.
In human sperm, the mitochondrial sheath is organized in a helix of approximately 13 gyres surrounding the axoneme in the midpiece.
The PC itself is composed of a microtubule-based core structure named the axoneme, which nucleates from a basal body and is surrounded by a ciliary membrane, which is continuous with the plasmatic membrane (Figure 1).
(2002) Hyperactivated motility of bull sperm is triggered at the axoneme by [Ca.sup.2+] and not cAMP.
Other ultrastructural defects those lead to ineffective ciliary motility include isolated absence of inner dynein arms or radial spokes, transposition of microtubules to the center of axoneme, missing nexin links etc., [sup][2] The clinical diagnosis of PCD is established in:
It has been reported [50] that the axoneme and mitochondria in sperms may be damaged by a high level of ROS.

A 9 + 9 + 2 axoneme pattern is the most common pattern within the Curculionidae (Gassner et al.
In addition, cryopreservative protection leads to changes in DNA, sperm cytoskeleton, inhibition of sperm-ovule binding, and destruction of sperm axoneme, and consequently reduction of its mobility.
