interneuronstransfer signals from neuron to neuron. 90% of neurons in the human body are interneurons
motor (efferent) neuronscarry signals to a muscle or gland called the effector. sensory neurons are located dorsally (toward the back) from the spinal cord, while motor neurons are located ventrally (toward the front or abdomen)
