WorksheetsCOMMUNICATION & THE ACTION POTENTIAL
Total questions: 17
Worksheet time: 7mins
Communication of information between neurons is accomplished by movement of chemicals across a small gap called the
AXON TERMINAL
NEURONAL CLEFT
SYNAPSE
VESICLE JUNCTION
ACTION POTENTIAL
The electrical impulses are created in the human body by the:
NEURO SYNAPSES
ACTION POTENTIAL
SODIUM/POTASSIUM PUMP
NEUROTRANSMITTERS
The speed of the electrical impulse through the axon, is influenced by the myelin sheath and
soma cells
Schwaan cells
Nodes of Ranvier
axon terminals
dendrites
Our nervous system takes information through our _________.
dendrites
action potential
central nervous system
senses
