Clubbing

No! Not those with party and drinks, but rather that which is on your fingers.
Your fingers club too, if you didn't know.

If you see anyone you know who has hands like those, or even hands which mildly looks like the one displayed, you should ask the person to see a doctor immediately. This is because the symptom of clubbing is almost universally, very bad.

Most lung diseases, heart diseases, liver diseases and even hyperthyroidism have clubbing as its symptoms.

Although the etiology of clubbing as a symptom of these diseases is unknown, scientists hypothesized that because these diseases cause the blood vessels in the fingers to vasodilate, nailbed tissues undergo hypertrophy and thus causes clubbing.

Please don't die?!

When your brain thinks that your body is dying, it sends out a signal to your muscles telling it to contract suddenly in an effort to wake your body up.

This is called a myoclonic jerk.

It normally happens when your heart rate and breathing slows down quicker than normal. Thus, the brain inteprets it as signal that the body is dying and the myoclonic jerk causes your body to have a "defibrillated" effect. Myoclonic jerks can happen in any part of the body. Most oftenly, the hands and feet.

Myoclonic jerks may also originate from lesions in the cortex and the spinal cord.

So, if you get a myoclonic jerk, 3 things. You might want to thank your lucky stars that your body prevented you from dying. Secondly, you might want to question your brain's intelligence if you knew that you were not dying. Thirdly, you might have to worry because you may have a brain problem.

Meiosis

Dear people, before I answer your questions, I think I have to clear a topic which I am super confused. Not confused by how it occurs, but rather by the technicalities and quantity.

The topic is Meiosis.
