Which of the following neuron structure - function parings is incorrect?
Axon - extension of cell body
Dendrite - sensitive to chemical and electrical signals
Cell body - contains cell nucleus
Axon - transmits signals to neighboring cells
Dendrite - unbranched receptor sites of signals from other neurons
When they are not being stimulated, neurons have an electrical charge across their membranes called the resting potential. This potential is______ charged inside. When a neuron receives a sufficiently large stimulus, and reaches a potential called the_______ , it produces an action potential. This causes the neuron to become_____ charged inside.
The neuron cell is made up of which of the following parts?
Axon
Dendrite
Soma
All of the above
