Does Your Tendon Protrude Out Of Your Wrist Like That This Is What It Means…


Does-Your-Tendon-Protrude-Out-Of-Your-Wrist-Like-That.-If-It-Does-It-Means-THIS Since the dawn of time, from the beginning of mankind,humans went through a number of processes from adaptation and evolution to natural selection until they got to the form we all know now. Looking back in history we can see that our ancestor looked a lot like us, but still there are many physical and anatomical features which are very different. We have the vestigial remnants throughout our body to prove it.

What are vestigial structures?

Wikipedia describes vestigial structures as “genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species, but have been retained during the process of evolution”.  Our bodies have been shaped by Mother Nature to sustain the changes and eliminate the unnecessary things from our body, the parts which aren’t required for survival, while we get to keep the parts we need in order to survive. Some body parts still remain, some of which we don’t even notice, while others, like the wisdom teeth or appendix, can cause us problems which can easily be repaired.

Examples of vestigial structures include the appendix, goose bumps, wisdom teeth, tonsils, male nipples, and the outer ear. Even though we have no need for these parts they are still present because they played an important role in our ancestors’ lives.

Do you want to see how you may have evolved?

We’ll share an interesting fact about the human body which you probably didn’t know. Lay your arm on a flat surface, with your palm facing up. Touch and press together your pinky finger and thumb and then raise your hand up at the wrist just a little bit, watch the video for better instructions. Do you notice a raised line in the middle of your wrist? If you do it means that you have a vestigial muscle in your forearm called palmris longus and the line bulging out is the tendons connecting the muscle. This muscle can be present on one arm, both or can be missing from both. 10-15% of the population doesn’t have it and you may be among the few. It shouldn’t upset you because this muscle has virtually no function at all. According to studies it doesn’t affect a person’s grip or strength.
