Question

Based on the simulation activity,explain how information travels in the nervous system

Answer 1

Information in the nervous system travels via electricity and chemical reactions. A neuron at rest is negatively charged, and when it is stimulated enough by a tiny positive charge, it sends a signal, called an action potential, down the length of its axon by opening and closing sodium and potassium channels at points along the axon. When the action potential reaches the end of the axon, it reaches the terminal buttons and makes them release chemicals called neurotransmitters into their synapses. Then,  they drift across the gap and bind to the next neuron's dendrites, they cause the next neuron to become more positively or more negatively charged.

Answer 2

Further explanation

The nervous system is a very complex network, but has an important role in the human body. Often referred to as the coordination system, nerves do have the main task of regulating all activities that occur in the body.

The performance of each organ, muscle activity, to the control of stimuli and reactions have been arranged in such a way by the body's nerves. The nervous system has at least 3 main functions:

Receive information in the form of stimuli received by the senses of the body,

Processing information received, and  Generate responses or provide responses to the information.  The nervous system is still divided into two based on its function. First is the central nervous system consisting of the brain and spinal cord. Second, the peripheral nervous system which consists of all neurons that exist outside the brain and spinal cord.

These two systems work together so that humans can carry out various activities, ranging from walking, talking, moving their hands, or feeling a variety of emotions and sensations towards something.

Overall, the nervous system in humans is composed of several parts of the organ. The part in question is the brain, spinal cord, sensory organs, and also all nerve cells (neurons) that function as a connector.
