Neurons

To facilitate communication between neurons

To provide structural support to the nervous system

To generate electrical impulses for the brain

To isolate neurons from each other

By varying the strength of the electrical impulse.

By varying the speed of the electrical impulse.

By varying the frequency of electrical impulses.

By changing the type of electrical impulse.

Sensory input, integration, motor output

Digestion, circulation, respiration

Growth, reproduction, metabolism

Protection, support, movement

Brain and spinal cord

Central and peripheral nervous systems

Somatic and autonomic nervous systems

Sensory and motor divisions

Fast and Slow

Electrical and Chemical

Direct and Indirect

Sensory and Motor

Transmitting electrical signals

Producing hormones

Providing support, nutrition, and insulation to neurons

Controlling voluntary muscle movement

They are much faster than electrical synapses.

They allow for direct transmission of electrical signals.

They provide more control and allow for signal modification.

They are less abundant, leading to more efficient processing.

More positive inside than outside.

More negative inside than outside.

Equal positive and negative charges on both sides.

Only positive charges inside and negative charges outside.

To generate action potentials.

To maintain the electrochemical gradient.

To transport neurotransmitters.

To physically stretch the membrane.

They are constantly renewing cells like skin cells.

They have a low metabolic rate.

They are some of the longest-lived cells in your body.

They are easily replaced if damaged.
