Did you know that your fingernails can tell you something about certain heart and lung diseases? It's called "clubbing".
The fingers become enlarged and the nails turn more curved. It isn't a sign of diagnosis, but if a physician sees clubbing on a patient, it can signal to do further tests to see what is happening internally. Now, something else.
For many men, the left te**is is usually lower than the right. Studies have shown that this condition is normal amongst various types of men, but the exact proportion varies. And that phrase about 70% of the human body being water?
That's an estimate. It can vary between people depending on age, s*x, and body mass. The smallest bone in the human body is the stapes. It is located inside the ear canal and is only a few millimetres long. And, despite it's name, the small intestine is longer than the large intestine. The small intestine is a few metres long in an average human, and the large intestine is only about 1.5 metres. Your belly button is also a scar.
It is the place where the umbilical cord was once attached, and where tissue had to regenerate to close the gap. Here's something else that can be odd.
The phrenic nerve supplies the diaphragm with motor signals, but also sends sensory signals from the area around the shoulder.
This means that irritation of the diaphragm can be mistaken by the brain as pain coming from the shoulder. This is known as referred pain.
There's also this thing called the "danger triangle" of the face. It's a region that resembles a triangle, formed by the corners of the mouth and the bridge of the nose. Infections in this area of the face can, rarely, lead to the infection reaching the cavernous sinus through venous connections and cause serious conditions such as cavernous sinus thrombosis. And please, don't try out the last fact.
Applying pressure to the carotid sinus in the neck can cause a reduction to the heart rate and a lowering of the blood pressure. This can result, in rare circumstances, to dizziness and even fainting.
So, no. Your anatomy is pretty cool without doing things to test it out.
