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.

They have special sense of hearing. They can differentiate between rustling of leaves or a tiger moving through a grass.

Tigers have more volume of brain than the other big cats.

They have a nervous system with complex brain, which has an extremely complex cerebrum.

"Tigers have the same nervous system as most animals." Enough said, but they have better neuro-muscular connections and twitch responses (faster reflexes), yet so do bears. Bears compete with big cats in terms of reflexes as well.

Their reflexes are probably comparable but that doesn't mean one won't react faster than the other nor does it mean that one is more or less agile than the other.
The simple act of jumping requires type 2b (fast twitch) muscle fibers and since the big cat is a better jumper than the bear does that mean it has more?
Probably not, it's just how they are built.

Type 2b muscle fibers are about for explosive movements, your fibers fire anaerobically (without oxygen). so if we are talking about
being able to get from your back to your all 4's, stalking in a crouching position then sprinting, jumping from greater heights or climbing than one would think that the cat would have more of the Type 2b fibers.
But that may not be the case, body morphology doesn't allow the bear to accomplish certain physical exertions as easily as the cat but we have to take into account the way the bear is built. A heavy and compact animal, flat footed and heavier bones isn't as friendly towards agility as it is towards blunt force.
But that doesn't mean that the bear doesn't have as fast of a reaction time. I'm sure if you had both the animals line up for a sprint and shot a gun off, the two contestants would react at the same time.

I'll I'm saying is that muscle distribution is one aspect of determining speed, agility and strength. But there are many more factors than just type 1 and type 2 muscle distribution. Even with in human beings, the type 1 or 2b or 2a distribution can be different, I'm sure the same is true with wild animals. Some animals may just be better at certain aspects than others of the same species.

Sorry to go off on a bit of a tangent. Reply
