It could be said that every part of the human body is somehow important and has its own function.
However, for some of them, usefulness is not their strong point, or they have only an aesthetic role, while some of them can also cause problems when they turn on.
1. Wisdom teeth - also known as "eights" are teeth that grow last, mostly in the second or third decade of life. It is difficult for a brush to reach them, so due to poor hygiene, they often get damaged, and sometimes they are removed because there is no room for them to grow.
2. Appendix – the popularly mistakenly called "cecum" is actually a worm-like outgrowth from the initial part of the large intestine (true appendix). It is prone to inflammation, which is why it is a frequent reason for visits to the surgeon.
3. Tonsils – groups of lymphatic tissue that play a role in protection against infections. However, sometimes this role fails and they often swell and make it difficult to pass through the mouth into the pharynx. There are specific indications for their removal, so you should consult with an otolaryngologist.
4. Adenoid – another tonsil at the transition from the nose to the pharynx. During growing up, it decreases, although in children it can remain enlarged and make breathing through the nose difficult.
5. Plica semilunaris – a small membrane in the inner corner of the eye that represents a rudimentary third eyelid. It is the main "culprit" for the yellowish deposits that we see in the corner of the eye in the morning when we look in the mirror.
6. Sinuses – cavities in the bones of the head. They have a minor role in reducing the overall weight of the skull bones and the resonance of the voice, but they often flare up when they cause problems.
7. Saphenous vein – since one artery that brings blood usually has two veins that take blood away, there is a large number of veins that we have "in reserve". The saphenous vein is, in fact, one of the more useful veins because it can be used in cardiac surgery as an autograft, where the surgeon removes it and transplants it to a heart that has blocked coronary arteries (bypass).
8. Membranous palm (palmar aponeurosis) – membrane located above the muscles of the palm. Although it plays a role in protecting muscle tendons, some people with diabetes or liver cirrhosis may experience contractures, when the membrane tightens and bends the fingers, requiring surgical intervention.
9. Arector pili - hair-raising muscles, it can be said that they do not fulfill their function since humans do not have fur. They can be seen when the skin is exposed to cold, i.e. when a person gets "chills".
10. Hair - mostly have only an aesthetic role. Hair partially protects the head from the cold, eyebrows reflect a person's emotional state and prevent sweat from flowing from the forehead to the eyelids, and eyelashes, in addition to being aesthetic, also play a role in reflexively closing the eyelids to prevent a foreign body from entering the eye.
