5 True/False questions
The birth of new neurons from undifferentiated stem cells → the action potential is carried into the CNS
These neurons act as sensory receptors that detect touch, pressure, pain and temperature → metabotropic receptor
What are effectors? → muscles and glands
During this phase the membrane potential is restored to the resting state → repolarization
The site of communication between two neurons or between a neuron and an effector cell → synapse
