It’s amazing to think that those massive blood vessels run right past the ear, and we don’t hear the blood roaring through them. But actually, we actually do hear it, but have over the course of hearing it constantly have learned to ignore it, and yet can still decipher a mosquito buzzing by our ears
Nice video. After looked Man body how is functions different different types, but that time I have remembered of God how is made nature. Thanks ❤️🙏👍👍❤️
I learnt the anatomy and pathways of the carotids by mnemonics for my preclinical dental exam in '75. Otherwise l had no idea where on earth they went. That got me into clinical studies. I qualified five years later. 😂
Up to a point. There are some serious design issues arising from the transition from walking on all four to two. notably the back is put under far to much strain. Also the neck needs to be stronger to support a heavier head. Humans break their necks fairly easily, which not only causes death but horrific paralysis as well.
@@patricksmith4424 Patrick, there are no examples of those transitional stages about which those evolutionary theories speculate. Humans have always walked upright since their beginning.
@kathleencole80 so when was their beginning? The missing link has yet properly to be found. What is for certain is that humans at some point did walk on all fours. There is a bit of tail at the end of the spine, also the spine when it leaves the pelvis is horizontal, this indicates walking on all fours. The spine then goes vertical. If humans were initially designed to walk upright then why is the spine not attached to the pelvis straight down?
@@patricksmith4424 Discoveries of artifacts (such as stringed musical instruments and hand tools made of bronze & iron) from the earliest of caveman days prove that humans used their hands as we still use our hands today. Another thing, in human anatomy we learn about that horizontal part of the spine, called the sacrum, which is actually larger in humans than in all other mammals for the very purpose of providing core body stability for sitting upright and for standing & walking upright - not for walking on all 4's.
This explains why the permanent damage to my neck from my workplace accident so many years ago causes dizziness and light headedness when the muscles & connective tissue swell up, as well as intermittent episodes of paralysis on my left side.
