3 Kinds of Neurons
- Sensory neurons gets information from external and internal stimuli.
- Interneurons form one neuron to another.
- motor neurons consist of muscles and glands.
All of these nerve cells carries an impulse through the Nervous System.
Pseudounipolar cells (example: dorsal root ganglion cells). Actually, these cells have 2 axons rather than an axon and dendrite. One axon extends centrally toward the spinal cord, the other axon extends toward the skin or muscle.
- Sensory (or afferent) neurons: send information from sensory receptors (e.g., in skin, eyes, nose, tongue, ears) TOWARD the central nervous system.
- Motor (or efferent) neurons: send information AWAY from the central nervous system to muscles or glands.
- Interneurons: send information between sensory neurons and motor neurons. Most interneurons are located in the central nervous system.
