thinking is a complex activity . give reason
Answers
Answer:
yes
Explanation:
Thinking is a complex activity, so it is bound to involve a complicated interaction of many nerve impulses from many neurons.If this is the case, it is no surprise that the thinking tissue in our body consists of dense networks of intricately arranged neurons. It sit sin the forward end of the skull, and receives signals from all over the body which it thinks about before responding to them. Obviously, in order to receive these signals, this thinking part of the brain in the skull must be connected to nerves coming from various parts of the body.Similarly, if this part of the brain is to instruct muscles to move, nerves must carry this signal back to different parts of the body. If all of this is to be done when we touch a hot object, it may take enough time for us to get burnt!How does the design of the body solve this problem? Rather than having to think about the sensation of heat, if the nerves that detect heat were to be connected to the nerves that move muscles in a simpler way,the process of detecting the signal or the input and responding to it ban output action might be completed quickly. Such a connection is commonly called a reflex arc (Fig. 7.2). Where should such reflex arc connections be made between the input nerve and the output nerve?The best place, of course, would be at the point where they first meet each other. Nerves from all over the body meet in a bundle in the spinal cord on their way to the brain. Reflex arcs are formed in this spinal cord itself, although the information input also goes on to reach the brain.Of course, reflex arcs have evolved in animals because the thinking-process of the brain is not fast enough. In fact many animals have very little or none of the complex neuron network needed for thinking. So it is quite likely that reflex arcs have evolved as efficient ways of functioning in the absence of true thought processes. However, even after complex neuron networks have come into existence, reflex arcs continue to be more efficient for quick responses.
Why is thinking a complex activity?
✍️Thinking is a complex activity, so it is bound to involve a complicated interaction of many nerve impulses from many neurons.
✍️If this is the case, it is no surprise that the thinking tissue in our body consists of dense networks of intricately arranged neurons.
✍️It sits in the forward end of the skull, and receives signals from all over thebody which it thinks about before responding to them.
✍️Obviously, in order to receive these signals, this thinking part of the brain in the skull must be connected to nerves coming from various parts of the body.
✍️Similarly, if this part of the brain is to instruct muscles to move, nervesmust carry this signal back to different parts of the body.
✍️Rather than having to think about the sensation of heat, if the nerves that detect heatwere to be connected to the nerves that move muscles in a simpler way, the process of detecting the signal or the input and responding to it byan output action might be completed quickly.
✍️Such a connection is commonly known as a reflex arc.
✍️Nerves from all over the body meet in a bundle in the spinalcord on their way to the brain.
✍️Reflex arcs are formed in this spinal corditself, although the information input also goes on to reach the brain.

✍️So, it is quite likely that reflex arcs have evolved as efficient ways of functioningin the absence of true thought processes.
✍️However, even after the complex neuron networks have come into existence, reflex arcs continue to be more efficient for quick responses.
✍️Therefore, thinking is a very complex process involving many actions in the body.
