- What are all the five reflex arc components for the Ciliospinal Reflex? What is the receptor, the type of the receptor, its location for this reflex? What sensory neuron takes the information to the control center? Is the control center in brain or in the spinal cord? What motor neuron is involved in this reflex? What is the effector for this reflex?What is the major difference between monosynapticreflexes and polysynaptic reflexes?This is the general order of events for a reflex arc. a) information relayed to the CNS, activation of a sensory receptor, activation of a motor neuron, response by the effector b) response by the effector, activation of a motor neuron, information relayed to the CNS, activation of a sensory receptor c) activation of a sensory receptor, information relayed to the CNS, response by the effector, activation of a motor neuron d) activation of a sensory receptor, information relayed to the CNS, activation of a motor neuron, response by the effector
- When describing the reflex arcs and the neural pathways involved we often limit ourselves to the nerves carrying information from the muscle or tendon to the spinal cord and back. However, it should be clear from our ability to feel the tendon tap as well as the results from the Jendrassik’s maneuver test that it isn’t this simple. What other neural connections must be present ?What are the components in a polysynaptic reflex arc in the order that they are activated. Then briefly describe the function of each. #1 #2 #3 #4 #5Describe a situation where a reflex arc would be activated that is not described in your lesson. Assume that the reflex arc has five components to it. Please choose a reflex that involves a body part below the neck. (If you have trouble with this, do an internet search for information on reflex arcs.) Which type of structure was first stimulated in the reflex arc? What is the name of the second structure involved in the reflex arc? Into what part of the nervous system did the second structure send its electrical signal? What is the name of the third structure involved in the reflex arc? Where is this third structure located? What is affected by the electrical signal sent by the third structure? (This will be the fourth structure in the arc.) Where is the cell body of the fourth structure located? What is affected by the electrical signal sent by the fourth structure? (This will be the fifth structure in the arc.) What does the fifth structure do in response to that electrical signal…
