Neurons - MrsMcFadin
... Types of Neurons • Neurons are classified according to the direction in which an impulse travels: 1. Sensory neurons = carry impulses from sense organs (eyes and ears) to spinal cord and brain. 2. Motor neurons = carry impulses from brain and the spinal cord to muscles and glands. 3. Interneurons = ...
