What are the three types of neurons and where do they conduct/convey impulses? and state if how many poles they have.
Sensory neurons convey impulses to the CNS (brain and spinal cord). They are either:
unipolar (one pole), or bipolar neurons (two poles)
Motor neurons convey impulses away from the CNS, to a muscle or a gland. A multipolar (many dendrites)
Connector neurons connect sensory neurons to motor neurons in the spinal cord and in the brain
