How does the spinal cord know and what to do, contained by a reflex(sudden movement controlledbe S.P.)?
Answers: Oh boy - one of my favorite reactions! That spinal loop is fascinating. It's programed into the muscles and nerves to just verbs away - the hand pulls back. That's usually the right movement, but if it isn't you can actually be injured by the reflexive movement - it is sudden and furious and completely thoughtless (sounds a lot like Georgie Bush).
Our body is made in such a opening that it knows how to defend itself. For example, when you touch a hot object, you without hesitation pull back your arm so as not to burn your hands/ fingers. The reflex allows us to respond much more quickly than if we have to consciously think about what to do and interpret the information to the central bashful system (CNS).
Basically, when there is a stimulus it runs down a pathway going to the CNS where it is interpreted and a definite recoil given. When you're eating something delicious, it transmits the signals to the brain and interprets it as "delicious" and you react by drinking more of the food. But when you eat something hot, you immediately spit it out; it's a reflex; a defense. The signal doesn't have to travel adjectives the way to the brain to be interpreted - or else, by the time it is interpreted, your tongue has burned disappointingly. Our body senses which stimuli needs to have an immediate counterattack and which does not.
The reflex arc is the pathway that results in a reflex. It is a basic unit of the nervy system and is the smallest and simplest pathway able to receive a stimulus, enter the CNS (usually the spinal cord) for immediate interpretation, and produce a response.
How does the spinal cord, or the brain for that matter know what to do? God made it that instrument.
