5 True/False questions
Bipolar Neuron → one axon and one dendrite
Unipolar Neuron → one single process leading away from the soma; afferent neurons are unipolar
Hyperpolarization → The membrane has become more negative than resting potential. Until the channels close.
Schwann Cells → the PNS glial cell that surrounds the dorsal root ganglion neurons
Neurotransmitters → a chemical released at the distal end of an axon that stimulates an adjacent cell; found in the synaptic vesicles of the axon terminal; initiates electrical current from one neuron to the next by diffusing across the synaptic cleft
