Bear and bigcats anatomy
|
Thanks I already saw it. I knew before itself they originated from an animal named bear dog. But notable feature or difference between big cats and bear is they have fast twitch muscle fibres in the mouth muscles just like dogs and other canids where as cats don't seem to have them in mouth muscles but in other parts of body providing them for outbursts of speed for shorter durations.

If we remove fur the face looks similar to a dog, no doubt they originated from dog like I thought the bear was hunted. But may be they picked up dead bear. That is good. No cruelty here. I mistook it.

*Actually, it was somehow prepared and put on display. “Koerperwelten der Tiere” (Body Worlds of Animals), an exhibition of polymer preserved animals of Gunther von Hagens, opens in Vienna on November 17 and runs until March 17, 2011. *I will edit and add; the bear ( post #73 ) is just an average brown bear; not a particularly muscular specimen.

IT reads like you feel sad for the bear because if you remove the fur from his face, he looks similar to a dog. Sounds like you are once again tossing insults. *However; perhaps I was misjudging your meaning. Therefore, I'll drop it here.
Yes, that is what i expected and that's why i said try to develop positive thinking.
Tiger's fast twitch muscle fibres in the mouth seem to be confined where as bear's fast twitch muscle fibres are seen almost all around the face. That seems to be the difference IMO. Or can anyone clarify?

That seems to be the difference IMO. Or can anyone clarify? I don't see any difference from the pictures you posted. Remember that fast-twitch fibers are whiter and slow-twitch fibers are redder.

The head and mouth seem to contain fast twitching muscle fibres which are labelled white. The forelimbs seem to contain plenty of fast-twitch fibers. Again, we might have to reconsider if big cats really do possess a higher fast-twitch fiber ratio than bears. Mammalian predators in general seem to possess more fast-twitch fibers than most other living creatures.
I accept. Fast twitch muscle fibres in facial region and forearms are lot more in bear than bigcats. But tigers seem to contain high fast twitch muscle fibres till elbow region. From then on its slow twitch fibres. This is good as the nourishment to fast twitch muscle fibres through slow twitch fibres does not seem to be effected in anyway. Whereas in bears it is tough to constantly nourish masses of fast twitch fibres for prolonged times through slow twitch fibres. So big cats can use fast twitch fibres for prolonged intervals so they are able to engage in prolonged battle lasting even for a fort night.

Skeletal system of tiger,
The skull is designed considerably well. It protect the eyeballs and the brain, and is also built in a way that allows maximum strength in its jaw, which is essential considering it is required when using the hunting methods of biting down on the neck of the prey. The skull is short and rounded, concentrating on all of the support and power into the teeth and jaws. In addition, the tiger is designed better that the humans because a tiger’s septum is made from hard bone, separating the cerebrum and cerebellum and protecting the brain more effectively, whereas the human's is made of a membrane. Tigers have 30 teeth which is peculiar as most carnivores have 42. They back teeth are specially designed to allow them to tear large chunks from their prey. They often swallow the large chunks whole instead of taking the time to chew their food. That is because their digestive system is designed to break down the food. They can eat large amounts of food in one setting when the food is readily available to them. The tiger's teeth are constructed with a gap between their back teeth and that allows them to bite deep into the neck of their prey. They will use their canine teeth to hold the animal in place until it dies. They small incisors at the front of the mouth are used to remove meat from bones and feathers from their prey. The tongue contains little spikes called papillae. They make the tough rough which helps them to remove fur and feathers from their prey before they eat it. The longer hind legs of the tiger are made to allow jumping, covering up to 10 meters in a single leap. Their forelegs have a strong and solid bone running through, which reinforces the tiger's landings and makes them able to support a massive amount of muscle tissue. This means that they are as strong as possible, which is important as the tiger because they use their forelimbs to grab and hold onto to struggling prey. The collarbone of the tiger is designed to facilitate the ability to achieve longer strides and running speeds without hindrance.
