Nervous System

The nervous system is composed of the ___, ___, and ___.

• heart, brain, kidneys
• lungs, liver, stomach
• brain, spinal cord, nerves
• eyes, pancreas, veins

What direction foes the electrical signal travel through the neuron?

• From dendrites, down the Axon, and out Axon terminalsThis is a correct answer

• From Axon terminals, down the Axon, & out of the dendrites

• Any direction up or down the cell

• From the Axon, to the Dendrites, and out the Axon terminals

What do Axon Terminals do?

• Intakes information from other neurons

• Produces fatty tissue for the Myelin Sheath

• Sends information to the next cell

• Controls the speed of electrical signal through the axon

What is the function of the nerve cells?

• They are responsable of your defense mechanism.

• They transmit signals or messages to other neurons, organs or glands.

• They transmit substances to your endocrine system to produce hormones.
