How to draw reflex arc

Reflex arc consists of a receptor, a sensory nerve, an association neuron, motor nerve and effector organ. The receptor may be a single cell or a group of cells. They receive information about stimuli and generate electrical potentials. The sensory nerve is associated with receptor. It carries the information in the form of electrical impulses from the receptor organ to the spinal cord. In the spinal cord, the sensory nerve makes connections with other neurons in the grey mater. These neurons are called inter neurons or association neurons. The neurons process the information and generate responses. The efferent fibers of motor nerves carry these responses from inter neurons to the effector organ which is usually a muscle. This makes the muscle to contract.
