Matrüka

The Matrüka is the anus of the Ibrófeneð, and represents the end of the digestive system that also comprises the Matošu, Tewaðup, and Vanýst. It also comprises a major part of the reproductive system, as it is the main exit point from which the Mabëžaró, the reproductive cells, can leave the body and thus be dispened in the Eŋi-Prëdurëp.

Etymology

The Matrüka, like its counterpart the Matošu, is derived from the word Maðër (which was often pronounced as 'Matër'), which is the word for 'to use'. Both terms change the tense of the verb to 'One that is used for __', with the blank in this case being the word 'Rërüt', that is, 'to defecate'. The 'ka' at the end is the part of the word that changes it to passive voice ('to be used for' vs 'to use for').

Anatomy and Physiology

The Matrüka is not a distinctive body part, but merely the lower boundary between the Vanýst and the outside world. It is a 10-15 cm ring, roughly matching the diameter of the Vanýst itself, over which the Ibrófeneð itself has no control, due to the fact that there are no muscles in that region. Instead, its importance is derived partly from the fact that it is one of the few places where the Оö-Ŋüžtú is known to connect with the Vanýst. This Оö-Ŋüžtú is one of the most unpredictable parts of the body, being formed as an arbitrary piece of amalgam, and it is generated from several spots along the Vanýst. These spots are its anchor points, serving as the main connectors keeping the Оö-Ŋüžtú stable, and one of these points is where the Matrüka is located. If the Matrüka is damaged (which is extremely common due to its proximity to the outside), the Оö-Ŋüžtú has a good chance of becoming freely-rotating, which has dire consequences for bodily systems that rely on it not freely moving, including the reproductive, vascular, and nervous systems.

The Matrüka's main purpose is to secrete various bodily substances that originate in nearby parts of the body. The most prevalent are spare chunks of food that did not get collected or processed by the Tewaðup; given the ad hoc nature of digestion, it is certain that there will always be some undigested residue left over. The Matrüka will thus dispense the pieces on the surface directly below the Ibrófeneð. This dispensing location is fairly predictable, and one can easily position a bowl or other container at that spot to collect the undigested residue and sent it back through the system for another pass.

Another aspect of the Matrüka's purpose is as the exit port for the secretion of reproductive material. This constitutes the process of Ýyorhïsïb, where at least two individuals of opposite genders dispense their respective reproductive cells in an external repository. These cells, called the Mabëžaró, are initially stored in the Maprëhu, which are two cavities within the body that are directly connected to the Vanýst. The two chambers house the two kinds of cells (the two 'genders'). Once a gender has been chosen, the unchosen cells are recycled back into the body, and the cavity is instead used as another food storage area. The act of secretion means the emptying of their chosen reproductive cells into the repository, which is through the Vanýst and Matrüka.

It must be noted that, once exiting their chambers, these cells are very volatile and reactive regardless of gender. A fairly common occurrence is that, since the Maprëhu cannot extend into the Vanýst and thus must dispense at an angle, the stream of cells does not cleanly exit the Matrüka but collides with a side thereof. This leads to a phenomenon known as Aparïŋ-Matrüka, where the affected chunk of body matter that the cells touch is corroded away through repeated acts of Ýyorhïsïb. Successive instances must take this into account, as the trajectory of cells is impacted by the partly/completely eroded body matter, sometimes becoming totally unpredictable. Furthermore, it may threaten the connection between the Vanýst and Оö-Ŋüžtú.

Development

The Matrüka represents the boundary between the regions of the Žëša and the Vëtiš, which are formed in separate compartments within the Eŋi-Prëdurëp, the receptacle for the Ýyorhïsïb process. It is not explicitly formed as a separate body part, but is merely born into existence when the proto-Vanýst collides with the film that separates the two regions. This delineation of body parts actually makes the Matrüka a vitally important tool; the formation of the Vëtiš themselves is by controlled outgrowths from the Matrüka's circular outline, which are systematically broken off, modified in solution, and reattached at select locations away from the Matrüka.

The Matrüka, being dependent on the Vanýst, exhibits the same changes that the Vanýst goes through. Thus, because only the Vanýst's outer layer is formed for much of the process, the Matrüka thus similarly starts out slightly wider than its final form. As more and more layers are added, the Matrüka itself is shrunk as well.

The Matrüka's placement as the focal point of the Vanýst and Оö-Ŋüžtú is due to the behavior of the former. Early on, after the Vanýst has formed as a thin shell, nutrients are funnelled through the system from the Matošu. Instead of being pure silicon, they are a mixture of elements including oxygen, nitrogen, fluorine, and chlorine, all of whom are depleted at intervals along the Vanýst due to reactions between the silicon shell and the various elements. In first third of the Vanýst, the oxygen supply is used up to form the Оö-Ëtavú; in the middle section, the nitrogen is used up to form the basis of what will become the brain, or Súro; the last part, made of fluorine and chlorine, births the unpredictable, maze-like curves of the Оö-Ŋüžtú. Although these elements react along all parts of the Vanýst's lower third, they move so fast that only a few react at a time. This results in very thin and tendrilly stubs that are subsequently swept up by the liquid outside the Vanýst.

At the very end, the liquid is stopped by the film separating the Vëtiš and the Vanýst, and collected there, the fluorine and chlorine are able to react with the Vanýst at their hearts' content, resulting in a very prominent outgrowth originating right there. From there, it becomes a chain reaction, as the dissolved and swept-away abortive pieces now rejoin the outgrowth and fuel its many curves. This can, and often does include the reattachment of the Оö-Ŋüžtú on the Vanýst at other points, but the outgrowth at the Matrüka is the only guaranteed anchor point.

Role in Communication

The Matrüka, although not the focal point of communication, nonetheless does influence the transmission of sounds (Ïfon-Wë) and vibrations (Ïfon-Kaðút) that comprise the two most widespread types of communication. This has to do with the Matrüka's role as the 'venting point' of the body (where sound and vibrations are free to exit the body) and its proximity to the Vanýst and Tewaðup, the most important source of these sounds and vibrations.

The six teeth of the Tewaðup are located at different places along the Vanýst, which is itself bookended by the Matošu and Matrüka. The upper teeth are farthest away from the Matrüka and closest to the Matošu, so the majority of its sound/vibrations travel through the latter. Similarly, the lower teeth are closer to the Matrüka and farther from the Matošu, so the majority of its sound/vibrations travel through the former. This has larger ramifications for the movement of the sound in relation to external observers, as well as the main methods of vibratory storage within the body itself.

The Ïfon-Wë

The destination that the majority of the sound goes to creates differences in how this sound is perceived by the recipient. For the top three teeth (A, E, and I), the majority of their sound goes to the Matošu, and comparatively less go to the Matrüka. For the bottom three teeth (O, U, and Y), the majority of their sound goes to the Matrüka, and comparatively less go to the Matošu. The Matošu excells in focused, clear sounds that stand out above the rest of the bodily movements, precisely because the elongated tube is able to direct the sound in a much clearer way towards the recipients. For the Matrüka, which only consists of an uncontrolled hole that is proximal to the ground, the sounds it receives are heavily muffled and tend to contribute to the background. This is not to say that being in the foreground or the background of the overall sound profile is beneficial or detrimental; the sounds of the background influence how the foreground sound is heard, and vice versa. However, the choice of which teeth to use in any given moment is decided almost always based on how that sound will come about through interactions with the Matošu and Matrüka.

Generally, one will use the Y tooth (the closest to the Matrüka) if a significant effect is desired for the background, and the O or U teeth (the two teeth above the Y and thus farther away from the Matrüka) if a more subtle effect is desired.

Vibratory Storage

At the Matošu and Matrüka are junctions that connect them with the larger Оö, or skeleton; the Matošu's ring connects it to the Оö-Ëtavú, while the Matrüka, as discussed above, is linked to the Оö-Ŋüžtú through several connections thereof. Any and all sound and vibrations that travel through the Matošu and Matrüka create secondary vibrations in the corresponding bone. If it is primarily sound that passes through, the secondary vibrations will be much more subtle than if it is mainly vibrations.

For the Оö-Ŋüžtú, its extremely complex and individualized bone structure means that, once the Matrüka transports vibrations to it, the behavior thereof is very hard to predict. However, it is almost always the case that vibrations stay within the bone itself, being only connected to other bones (like the Оö-Fýtap and Vëtiš-Húrobü) through tiny gaps only traversible by electricity. Instead, the vibrations are mainly used as a reference point that the body can consult, perhaps to ensure that they had said the right thing. Subconsciously, it is an indicator of reality; the Оö-Ŋüžtú's subtle vibrations are felt by the individual as a natural byproduct of speech, and to lose that (through the detachment of the bone from the Matrüka) creates highly disorienting effects.
