- Why is response time in a monosynaptic reflex much faster than response time in a polysynaptic reflex?What is the major difference between monosynapticreflexes and polysynaptic reflexes?What are the components of a reflex arc and what is the difference between a somatic motor reflex and a visceral reflex arc?
- The motor neuron involved in reciprocal innervation of the withdrawal reflex inhibits the extensor muscles of the limb. Considering what you learned about stretch reflexes, why does this make sense?what is typical reflex pathway containing three different nerve cell types. What function does the respective cell have?Is the stretch reflex monosynaptic or polysynaptic? Explain
- 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 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?Identify the Golgi tendon reflex (which is an innate reflex) as (a) spinal or cranial, (b) somatic or visceral, (c) monosynaptic or polysynaptic, and (d) ipsilateral or contralateral.
