5 True/False Questions
Afferent Neurons → carry signals toward the CNS from the body periphery; sensory neurons
Multipolar Neuron → one axon and multiple dendrites; efferent neurons and interneurons are multipolar
Nissl Bodies → essentially rough endoplasmic reticulum, important metabolically
Absolute Refractory Period → one axon and multiple dendrites; efferent neurons and interneurons are multipolar
Repolarization → K+ moves out of the cell causing the membrane potential to move in a negative direction.
