The way the horse's pastern joints and tendons don't shatter during grueling gallops is amazing, while those tiny structure (by comparison to the horse's size and weight) are bearing the weight and concussion during the galloping gait, which is massive
This Horse Leg explanation is really nice: A HORSE (Equus caballus) can gallop at a speed of up to 30 miles per hour (50 km/h). Although this involves considerable mechanical work, relatively little energy is spent. How is this possible? The secret is in the horse’s legs. Consider what occurs when a horse gallops. Elastic muscle-tendon units absorb energy when the leg steps onto the ground, and much like a spring, they return it, propelling the horse forward. Furthermore, at a gallop the horse’s legs vibrate at high frequencies that could injure its tendons. However, the muscles in the legs act as dampers. Researchers call this structure a “highly specialized muscle-tendon design” that provides both agility and strength. Engineers are trying to imitate the design of the horse’s legs for use in four-legged robots. However, according to the Biomimetic Robotics Laboratory of the Massachusetts Institute of Technology, the complexity of this design cannot be easily duplicated with current materials and engineering knowledge. What do you think? Did the structure of the horse’s legs come about by evolution? Or was it designed?
I meant why the horse had developed like that ie. i know that horses had three digits which became lost as they weren't needed etc. I watched this to form part of a piece of coursework I had at the time at college and I was asked why the horses adaptations had caused better chances of survival or something like that.
Two questions: 1) Is the navicular bone sort of like a Kneecap? 2) If I go running through a field at speed, I am highly likely to sprain my ankle. Hence, I have always wondered how a Horse with such huge upper body mass, relatively smaller leg bones and a much smaller "foot" can manage this task without also injuring its Pasterns as I do my ankle? Thanks Doctor.
the 1st, 2nd, and 3rd last bones you mentioned you called them metacarapals.. that is incorrect... they are p1 Phalanx 1 (long pastern, p2 Phalanx 2 (short pastern) and p3 (coffin)
@@artemisiagentileschi2400 if you listened correctly, you would have noticed the mistake too. Even veterinary professors can misspeak, and there's nothing wrong with pointing that out!

WE NEED MORE LECTURES, LIKE JOINTS TENDONS. I ACTUALLY USE THESE VIDEOS WHEN I STUDY EQUINE SCIENCE.
THANKS!!!!!!!!!!!!!!!!!!!!!!
Concise and complete, your an A+ professor. Thank you.
Well done. Just what I needed to understand. Thank you. Still useful in 2021.
You made this very easy to retain! Thank you!
These videos are brilliant, thank you so much
These are quite helpful. Thank you!
Thank you for this ❤️
Wow 🤯
Definitely like & subscribed
Þank you for sharing!
thanks very helpful
E
asy to learn now.Thans
Wow I wish it joints as well
You are great thax
Thanks madam very nice video
1:13 I do not know, I have seen some horses do some crazy things lately.

@@johnnyleesteele God's design 👍
I want to know more about horse. Suggest me plz
Ma'am 💚
Please make video on ox skeleton
Please could you share reasons to why the skeleton is the way it is, I like your videos though.

That's the way GOD created them... you can see whales have hand bones inside their fins... no mistake... they're there for a reason...
she said metacarpal the second time, so she was just mistaken. The first time she says phalanx
She made the comparison of the bones in the human hand... it would be the metacarpal bones... or the fingers...
Wouldn't the chestnut be the missing bone. And the navicular bone also be one of the missing bones
Two questions:
1) Is the navicular bone sort of like a Kneecap?
2) If I go running through a field at speed, I am highly likely to sprain my ankle. Hence, I have always wondered how a Horse with such huge upper body mass, relatively smaller leg bones and a much smaller "foot" can manage this task without also injuring its Pasterns as I do my ankle?
Thanks Doctor.
It would be the fingertip... and the coffin bone where the fingernail or hoof grows from...
Wile, I have also wondered the same often, it's amazing all these small delicate looking bones joined together can support a large upper body.
the 1st, 2nd, and 3rd last bones you mentioned you called them metacarapals.. that is incorrect... they are p1 Phalanx 1 (long pastern, p2 Phalanx 2 (short pastern) and p3 (coffin)
the 2n3 are metacarpal bone; the 1st carpal bone
They are the metacarpal in your hand... aka your fingers... she's been comparing them... human to horse
You're correcting a veterinarian professor? Would you like to teach the class Ms. Knowitall?

Was thinking the exact same. Thanks for mentioning.
اضحك رح نشوف بالنهاية مين رح يبكي 😊
Over evolution, over million of years, Darwin saw the first and fifth metacarpal bone disappear.
That's the way they were created... not evilution
Oh yes you very right, God's design, evolution I detest that word, thank you MRGF78.
