Question

what is the role of neuroglia in the nervous system? *
to support and protect neurons
to produce electrical impulses
to communicate with other cells
to store information

what are neurotransmitters and how do they play a role in the nervous system?

• 1 point

chemical messengers that transmit electrical impulses from one neuron to another
electrical impulses that transmit information from one neuron to another
structures that support and protect neurons
none of the above

what are the two major divisions of the nervous system? *
1 point
central and peripheral
sensory and motor
autonomic and somatic
sympathetic and parasympathetic

Explanation:

1. Neuroglia (glial cells) act as support cells for neurons, providing structural support, protection, and nutrient supply, while neurons produce electrical impulses and communicate.
2. Neurotransmitters are chemical molecules released at synapses to carry signals between neurons, converting electrical signals to chemical and back to electrical.
3. The nervous system's two primary divisions are the central nervous system (brain and spinal cord) and peripheral nervous system (all other nerves). Sensory/motor, autonomic/somatic, and sympathetic/parasympathetic are subdivisions of these main divisions.

Answer:

1. To support and protect neurons
2. Chemical messengers that transmit electrical impulses from one neuron to another
3. Central and peripheral
