Слайд 3 The appendix (or vermiform appendix; also cecal [or caecal] appendix; also vermix) is a blind-ended tube

The appendix (or vermiform appendix; also cecal [or caecal] appendix; also vermix) is a blind-ended tube connected to the cecum,

connected to the cecum, from which it develops embryologically. The cecum

is a pouchlike structure of the colon, located at the junction of the small and the large intestines.
The term "vermiform" comes from Latin and means "worm-shaped".

Слайд 4 The human's appendix averages 11 cm in length but

The human's appendix averages 11 cm in length but can range from

can range from 2 to 20 cm. The diameter of

the appendix is usually between 7 and 8 mm. The opening of the appendix is occasionally guarded by the valve of Gerlach, named after German anatomist Joseph von Gerlach. This valve consists of a semicircular fold of mucous membrane. The appendix is usually located in the right lower quadrant of the abdomen, near the right hip bone. Its position within the abdomen corresponds to a point on the surface known as McBurney's point.

Слайд 5 Found that the appendix located on the boundary

Found that the appendix located on the boundary between the thin

between the thin and thick intestines, during the evolution

of mammals arose independently in different species about 32 times. these data may indicate that the appendix - not a useless vestige, a body that plays an important role in body.

Слайд 6 Function of the appendix: digestive (reservoir for the

Function of the appendix: digestive (reservoir for the bacteria involved in

bacteria involved in the digestion certain types of food),

endocrine, immune. Furthermore, the appendix is used as material for reconstructive surgery of the genitourinary system studied the location of the appendix and its role.

Слайд 7 Variants of the location of the appendix: 1

- typical; 2 - medial; 3 - pelvic; 4

– Ascending - along the right side of the channel; 5 - obstructive; 6 - retrocecal; 7 - retrperitoneal; 8 -the left side.

Слайд 8 Most often the appendix is behind and below

Most often the appendix is behind and below the end of

the end of the ileum (the typical location) within

the right iliac fossa;

Слайд 9 Medial location – appendix is shifted to the

Medial location – appendix is shifted to the midline and is

midline and is located close to the top or

at the root of the mesentery of the small intestine that causes features of the clinical picture of the medial appendicitis

Слайд 10 Pelvic location - at anomalies of the cecum

it is located in the pelvis

Слайд 11 Retrocecal position - located behind the dome of

the cecum

Слайд 12 In cases where the cecum is covered by

peritoneum mesoperitoneally, process may be in the retroperitoneal space

- a retroperitoneal position.

Слайд 13 At anomalies of the cecum it is located

under the liver - subhepatic location

Слайд 14 The appendix is the only organ in the

The appendix is the only organ in the body which is

body which is said to have no anatomy. When

compared to the hour hand of a clock, the positions would be:
12 o clock: Retrocolic or retrocecal (behind the cecum or colon)
2 o clock: Splenic (upwards and to the left – Preileal and Postileal)
3 o clock: Promonteric (horizontally to the left pointing the sacral promontory)
4 o clock: Pelvic (descend into the pelvis)
6 o clock: Subcecal (below the cecum pointing towards inguinal canal)
11 o clcok: Paracolic (upwards and to the right)

Слайд 15 Most common position of appendix (75% of cases): Retrocecal Second

Most common position of appendix (75% of cases): Retrocecal Second most common

most common position of appendix (20% of cases): Subcecal If the

appendix is very long, it may actually extend behind the ascending colon and abut against the right kidney or the duodenum; in these cases its distal portion lies extraperitoneally.

Clinical importance of appendicular location...Exceptions exist in the classic prasentation due

classic prasentation due to anatomic variability of the appendix
Appendix

can be retrocaecal causing the pain to localize to the right flank
In pregnancy, the appendix can be shifted and patients can present with RUQ (Right upper quadrant) pain
In some males, retroileal appendicitis can irritate the ureter and cause testicular pain
Pelvic appendix may irritate the bladder or rectum causing suprapubic pain, pain with urination, or feeling the need to defecate
Multiple anatomic variations explain the difficulty in diagnosing appendicitis

Pain exacerbation of appendicitis gets worse with rotation medially and laterally in case of appendix lying against obturator internis muscle.

Слайд 17 Conclusion

ConclusionAppendix — this reliable storage for bacteria to which intestines contents

which intestines contents thanks to what the body can

be peculiar "farm" where useful microorganisms breed usually don't get. It had especially important role in ancient times, but with development of understanding of the principles of work of a human body people with a remote appendix can compensate substantially it to function, using the means normalizing intestinal microflora (especially after a course of treatment slabovsasyvayemy antibiotics). Also, how some researchers [who believe?], because of significant increase in population density the modern person can receive bacteria and from other people.

The appendix plays a saving role for preservation of microflora, it is a colibacillus incubator. Exactly here the original microflora of a thick gut remains. The appendix — is the body which is carrying out the same function for intestines, as almonds for lungs. It contains conglomerates of lymphoid follicles and functions as part of uniform functional system of mukozalny immunity.
