Bear and bigcats anatomy
|
  *This image is copyright of its original author The bear's skeleton looks more like that of a dog. That is why they are related to the dogs, wolves, and foxes. The only difference between the bones of a bear and a dog is the weight of the bones. Also, the grizzly's teeth and skull are not as adept as a dog's for biting and shearing. Nonetheless, the grizzly's raw strength more than makes up for biting and shearing. Although bears have short limbs, the sheer strength of their bones allows for great support.The skeletal system allows the animal to be supported in sudden changes of support in different environments. Examples are in water when different organism's bodies are made lighter (archimedes force). Another example is in land and air when the body is not supported as if in the water. As shown in the diagram above, the grizzly bear's skeletal structure is a like to that of a dog or wolf, in where the snout is narrow and their neck is long. Though this is the case, the grizzly bear walks more like a human. Usually mammals walk on their toes (digitigrade) which helps them walk fast. But the grizzly bear puts it foot sole down on the ground just like a human. The grizzly's hands are big enough to used for catching animals, attacking predators and protecting itself. The legs are also very short but strong enough to support the big body that it has. Both the hands and feet of the grizzly have phalanges which just like many bones of the grizzly, can be found in human anatomy. Like most living things, a skeleton is a vital system. The skeletal system's process is to do three things, protect, support and provide movement for the body.

About posts #90 and #91 Parvez, you neglected to post the source.
An edit here: also posts #44, #52, #68, and #70 ... If you believe that you have found some good information; then post the source. Otherwise ... why should we accept it? ... Even then; it all depends on the credibility of your sources.
Mr.brotherbear I dont understand what you want from me. I just bolded prominent features not that I hate bears. How many times I am saying this. Yet you keep on targeting me. Did you mention sources for every post of you. I don't mind posting the sources but it is your attitude that hurts. Once again develop sportive honest attitude is what I can say.

Once again develop sportive honest attitude is what I can say. If I post from a book, I give the book title and author. If I post from an online site, I give the site. This way, what you post can be checked out. Also, we can learn something of the author of the source; is he a scientist, an animal trainer, or a door-to-door vacuum cleaner salesman.

Parvez asks if I am a door-to-door vacuum cleaner salesman - no. I am a poster here who seldom fails to reveal my sources. When I read posts; especially those giving questionable "facts" with no source given, I tend to view those posts as irrelevant and non-factual.
pretty fine. I was just curious if you are biologist. Anyways I will post sources as soon as I go on to pc.

http://www.healthline.com/symptom/drooling Very good. However, you read about the heart rate of bears slowing down during hibernation and you conclude that bears have weak hearts. You see a bear drooling during a fight on a video and you post about the causes of a human baby drooling stating that bears have a problem with this. You're reaching...

I did not come to conclusion about drooling after one video. I watched many videos after which i concluded that. Even heart strength relative to other body parts I can even now say let the scientific study be conducted. Till then no heated debates please.
I have a question mr.bear expert brotherbear. Why do you think bears developed large and thick bones in their skeletal system while no other omnivores or carnivores bones have that feature?

I am sure that you are about to enlighten all who read this.
You actually mistook me, I just asked a doubt. Not to degrade bears here.
Anyways back to the topic, Nervous system of tigers: Tigers have the same nervous system as most mammals. The nervous system contains a brain, spinal cord and vertebrae. The vertebrae protects the spinal cord and is very important to the tiger's everyday life. Following is the description of the nervous system of a Tiger (and all mammals) which comprises of: • The central nervous system consisting of the brain and the spinal cord. • The peripheral nervous system consisting of the cranial nerves from the brain, the spinal nerves from the spinal cord and the sense organs. The sense organs are the structures which receive stimuli, so they are called receptors. They keep the central nervous system informed of any change in the surroundings by initiating nervous messages called impulses which are then transmitted to the central nervous system. A nervous impulse, like an electric current, travels at great speed. It is transmitted within a fraction of a second. For instance, when a person touched your hand from behind, you feel it almost immediately. If any action is to be taken in response to the stimulus the central nervous system will send impulses to the muscles. The muscles will then carry out the required effect e.g. the muscles in the arm may contract and the hand is jerked away. Therefore, muscles are known as effectors. The structures which transmit impulses from the receptors to the central nervous system from the latter to the effectors are the nerves.
