psy 200 chap 3 three types of neurons

What are three types of neurons? 

sensory neurons, motor neurons, and interneurons

Sensory neurons:

recieve info from the external world and convey this info to the brain via the spinal cord. They have specialized endings on their dendrites that recieve signals for light, sound, touch, taste, and smell- ex: sensory neurons in our eyes are sensitive to light 

Motor neurons:

carry signals from the spinal cord to the muscles to produce movement 

Interneurons:

connect sensory neurons, motor neurons, or other interneurons. Most of the nervous system is composed of these. Some carry info from sensory neurons to the nervous system, others carry info from the nervous system to motor neurons, and others perform a variety of info-processing functions within the nervous system
