Activity 3: Somatic Reflex Arc-The simplest neural circuit "Why do I pull my hand back from a hot stove before I even feel the heat?" Spinal cord Action WAND Afferent neuron axon (sensory) Efferent neuron axon (motor) Muscle (effector) Finger(receiver) Source of heat A somatic reflex arc Reflexes are an automatic response to a stimulus. USE THE INFORMATION IN THE DIAGRAM TO HELP YOU ANSWER THE QUESTIONS. 1. In the diagram shown above, what is the stimulus? 2. What is the response? 3. Does it appear, based on the model, that the brain is involved at all in this particular reflex action? 4.Somatic reflex arcs have five essential components. Based on the model and your knowledge of anatomy, describe the flow of information in a somatic reflex arc.
Expert Answer
Answer 1. As shown in the above image of somatic reflex arc, the source of heat i.e. the stove is the stimulus which stimulate the reflex response. Answer 2. The response is the pulling of hand from stove upon feeling to heat avoid burning of the han
