An axoneme is a bundle of nine microtubules forming the internal scaffolding of a cilium, with two extra microtubles connecting the others if the cilium is motile.

What is function of midpiece of sperm cell?
Middle piece is formed of mitochondiral spiral , nebenkern around the proximal part of axoneme. The mitochondria are the carriers of the oxidative enzymes and the enzymes which are responsible for oxidative phosphorylation. So the middle piece is the power house of a sperm
What is the function of the Cilium in cells?
Now, let us sit back, review the workings of the cilium, and consider what it implies. Cilia are composed of at least a half dozen proteins: alpha-tubulin, beta-tubulin, dynein, nexin, spoke protein, and a central bridge protein. These combine to perform one task, ciliary motion, and all of these proteins must be present for the cilium to function. If the tubulins are absent, then there are no filaments to slide; if the dynein is missing, then the cilium remains rigid and motionless; if nexin or the other connecting proteins are missing, then the axoneme falls apart when the filaments slide. What we see in the cilium, then, is not just profound complexity, but also irreducible complexity on the molecular scale. Recall that by "irreducible complexity" we mean an apparatus that requires several distinct components for the whole to work. A mousetrap must have a base, hammer, spring, catch, and holding bar, all working together, in order to function. Similarly, the cilium, as it is constituted, must have the sliding filaments, connecting proteins, and motor proteins for function to occur. In the absence of any one of those components, the apparatus is useless
What to sperm consist of?
The spermatozoon is a remarkably complex metabolic, locomotive and genetic machine. It is approximately 60 microns in length and is divided into 3 sections: head, neck and tail. The oval sperm head consists of a nucleus containing the highly compacted DNA, and an acrosome that contains the enzymes required for penetration of the egg shell for fertilization. The neck maintains the connection between the sperm head and tail and consists of the connecting piece and proximal centriole. The tail harbors the midpiece, principle piece and endpiece. The tail midpiece contains the axoneme or engine of the sperm and the mitochondrial sheath, the source of energy for movement. Physiologically, the sperm axoneme is the true motor assembly and requires 200-300 proteins to function. Among these, the microtubules are the best-understood components. Sperm microtubules are arranged in the classic "9+2" pattern of 9 outer doublets encircling an inner central doublet. Defects in the sperm axoneme are well-recognized causes of ciliary dyskinesias that are routinely associated with infertility.

What is the organelle of pcd syndrome?
PCD (Primary Ciliary Dyskinesia) is a genetic disorder that affects cilia. Cilia are hair-like structures found on the surface of cells. The organelle involved in PCD is the ciliary organelle, which includes the basal body, axoneme, and associated proteins. Dysfunction of these organelles leads to impaired ciliary movement and various respiratory and sinus-related symptoms.
