Aim: Nerve Control

Aim: Nerve Control. Nervous Coordination. Types of neurons. Sensory neurons (afferent) receive initial stimuli. Interneurons (associative) are located in the brain or spinal cord. Motor neurons (efferent) stimulate effectors (muscles/glands that perform a response.). Neuron Structure.
