Question

Describe the function and main structures of the nervous system. Describe the state of a resting neuron, including the charges inside and outside the cell.

Answer 1

Answer:

The function of the central nervous system is to control all function of the body and mind and to integrate all sensory information received and and respond accordingly.

The central nervous system is made up of the brain and the spinal cord and its neurons.

The resting state of a neuron is  -70 mV (mV=millivolt) - which means that the inside of the neuron is 70 mV less than the outside of the neuron, therefore, at rest, there are relatively more sodium ions outside the neuron (which are negatively charged) and more potassium ions inside that neuron (Positive charge)
