- For other uses, see Atrium. The atrium (plural: atria) is one of the two blood collection chambers of the heart. It was previously called the auricle, but that name is now used for an appendage of the atrium. The atrium is a chamber in which blood enters the heart, as opposed to the ventricle, where it is pushed out of the organ. It has a thin-walled structure that allows blood to return to the heart. There is at least one atrium in animals with a closed circulatory system.

- (im-brĭ-ka′shun) 1. An overlapping of the free edges of tissue in the closure of a wound or the repair of a defect. 2. A regular overlapping of a surface, such as the slight, horizontal, scalelike ridges on the cervical third of the labial surface of some anterior teeth. The striae of Retzius are incremental growth lines seen in enamel and are the result of enamel development. When viewed microscopically in cross-section, they appear as concentric rings. In a longitudinal section, they appear as a series of dark bands.

Pilus Attachment of bacteria to host surfaces is required for colonization during infection or to initiate formation of a biofilm. A fimbria is a short pilus that is used to attach the bacterium to a surface.

- Pili are typically longer and fewer in number than fimbriae. 2. The short attachment pili or fimbriae are organelles of adhesion allowing bacteria to colonize environmental surfaces or cells and resist flushing. 3.he pilus has a shaft composed of a protein called pilin with an adhesive tip structure at the end having a shape corresponding to that of specific receptors on a host cell. 5. The same bacterium may switch the adhesive tips of the pili in order to adhere to different types of cells and evade immune defenses.

Fimbria (bacteriology) This appendage ranges from 3-10 nanometers in diameter and can be up to several micrometers long. Fimbriae are used by bacteria to adhere to one another and to adhere to animal cells and some inanimate objects. A bacterium can have as many as 1,000 fimbriae. Fimbriae are only visible with the use of an electron microscope. They may be straight or flexible.

Fibula The fibula (/ˈfɪbjᵿlə/) or calf bone is a leg bone located on the lateral side of the tibia, with which it is connected above and below. It is the smaller of the two bones, and, in proportion to its length, the slenderest of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below the level of the knee joint, and excluded from the formation of this joint.

- These strings originate from small mounds of muscle tissue, the papillary muscles, which project inward from the walls of the ventricle. When the cusps close, the chordae tendineae prevent them from swinging back into the atrium cavity (the upper chamber).The chordae tendineae are strong, fibrous strings attached to the leaflets (or cusps) of the heart on the ventricular side; i.e., the lower chamber.hese strings originate from small mounds of muscle tissue, the papillary muscles, which project inward from the walls of the ventricle.

Fimbriated fold of tongue (Fimbria is Latin for fringe). Some people, have small (<1 cm) horn-like triangular flaps of skin (mucosa) under their tongue. They are on each side of the frenulum (the piece of tissue connecting the bottom of the tongue to the inside of the mouth) under the tongue and run parallel next to the two distinct veins. They typically appear in pairs and may even be up to 4 or more sets, but for even those who have them only two closer to the tip are distinctly visible while the others are very minor or just small bumps.

Enterobacteriaceae Most members of Enterobacteriaceae have peritrichous, type I fimbriae involved in the adhesion of the bacterial cells to their hosts. Some enterobacteria produce endotoxins. Endotoxins reside in the cell wall and are released when the cell dies and the cell wall disintegrates.

Atrial Fibrillation What Is Atrial Fibrillation? Atrial fibrillation (A-tre-al fi-bri-LA-shun), or AF, is the most common type of arrhythmia (ah-RITH-me-ah). An arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. AF occurs if rapid, disorganized electrical signals cause the heart's two upper chambers—called the atria (AY-tree-uh)—to fibrillate.

What are Villi? Villi, the singular of which is villus, are finger-like projections in the small intestine that help absorb food more efficiently in the body. The small intestine is an organ in the body in which most digestion occurs.

- Pili and fimbriae are structurally similar to flagella and are composed of one or a few proteins arranged in a helical fashion. Figure 2-49 shows pili isolated from Neisseria gonorrhea. Each protein subunit assembles on the growing structure at the tip, as is the case with flagella.igure 2.49 Pili and fimbriae. The pili shown in this micrograph are those of Neisseria gonorrhea with Tobacco Mosaic virus (the thicker structures) added as a size reference. The width of the Tobacco Mosaic virus is 0.018 µm.

Fimbriae of uterine tube In the female reproductive system, the fimbria (plural, fimbriae) is a fringe of tissue around the ostium of the Fallopian tube, in the direction of the ovary. An ovary is not directly connected to its adjacent Fallopian tube. When ovulation is about to occur, the sex hormones activate the fimbriae, causing it to swell with blood and hit the ovary in a gentle, sweeping motion. An oocyte is released from the ovary into the peritoneal cavity and the cilia of the fimbriae sweep the ovum into the Fallopian tube.

Bacterial Pili (Fimbriae): Characteristics, Types and Medical Importance 3.57 / 5  ( 7 ) Bacteria possessing pili include Neisseria gonorrhoeae and some strains of Escherichia coli, Salmonella and Shigella species. Fimbriae (pili) are shorter, straighter and more numerous than bacterial flagella and are composed by subunits of protein called pilin. Example: Mutants of Neisseria gonorrhoeae that do not form pili are nonpathogen. 2  Sex pili (conjugation tube): It is a specialized kind of pili that forms the attachment between male (donor) and the female (recipient) bacteria during conjugation and acts as a conduit for the passage of DNA.

- For example, in horses, the caecum is the main site for the symbiotic bacteria which break down food (eg. cellulose) for the horse. The caecum absorbs water and salts from undigested foods before they continue on to the large intestine. The caecum of a squid has a digestive function.erbivores have a larger cecum due to the fact that it functions as a fermentation (chemical conversion of sugar into ethanol) chamber, where symbiotic bacteria convert the sh … redded grass, leaves etc into nutrients for the absorption of cells in the small intestine.
