Why do you say that the nervous system the control center of the human body?

Answer 1

Because the nervous system is what controls all the various tissues of the human body, without it pretty much nothing would occur in the body. You wouldn't pick up any "information" from your external or internal environment and so wouldn't learn. It also consists of motor neurons which send signals to our muscle cells to contract(our cells perform there functions under the regulation of the nervous system). Practically none of the things your body does, from the vasodilation of blood vessels in the skin, in response to changes in temperature or the secretion of hormones such as adrenalin, to the contraction of bicep muscles to lift a weight wouldn't occur without it.(although some muscles are myogenic and don't require nervous impulses in order to conract, such as the heart muscles, the rate of contraction etc are still controlled by the nervous system. In short EVERYTHING is controlled by the nervous system! and that's why it's called the control centre of the body.

The nervous system is considered the control center for the body because it is responsible for all functions of the body. The nervous system is what sends messages to your organs function and it also tells you limbs when and how to move.

Answer 2

Because it controls all the body's functions.there are 3 types of neurons. Effector neurons, sensory and relay neurons. Sensory neurons get a message from the sensory organ(e.g pressure receptors in the skin). then they are sent to the CNS(central nervous system) which includes the spinal cord(involuntary actions/reflex) or the Brain(voluntary action) From here the message is sent via a relay or intermediate neuron to the effector neuron.the effector neuron then sends the message to the effector muscle to perform the due action. An example of a simple reflex action is a human hand (sensory organ in skin) touching a hot surface and then suddenly jerking away(biceps and triceps). Hope this helps!
