description | Introduction: The vermiform appendix in human is considered
to be a vestigial organ by most of the authors. Absence of
appendix is already reported in Indian population. Whether the
human appendix is performing any function is debatable but
when present it can create trouble. So if there is no appendix we
can escape the ill-effects of the organ. With this hope the study
has been done to see whether the appendix is really going to be
rudimentary or absent or not.
Marerials and Methods: Length, external diameter, number of
lymphoid follicles, maximum diameter of the follicle or submucous
coat, thickening of the muscle coat and seromucosal thickening
of freshly removed appendix from human cadavers were seen.
After fixation in 10% formal saline tissues were stained with
haematoxylin-eosin stain and photographs were taken. The
results had been tabulated and statistically correlated.
Result: The parameters like number of lymphoid follicles, length
and diameter all are changed as per the age advancement which
is strictly indicating some functional activities of the organ which
is against the idea of vestigiality of the appendix.
Conclusion: Human appendix cannot be called a vestigial organ
unless the functional inactivity is proved. Lymphoid changes
which occur after birth to provide the gut immunity is needed to
be proved by further studies. There might be incidental absence
or rudimentary appendix in human body, but that does not
indicate that we would not have any appendix in future. |
