The reflexes that control the most rapid, stereotyped motor responses to stimuli are (a) monosynaptic reflexes, (b) polysynaptic reflexes, (c) tendon reflexes, (d) extensor reflexes.

In a reflex arc, the __________ transmits afferent impulses to the central nervous system.

Stretch reflexes would be hypoactive in all of the following conditions EXCEPT __________.

Reflexes that result from practice or repetition are known as __________.

The following are the steps involved in a neural reflex.1. activation of a sensory neuron2. activation of a motor neuron3. response by an effector4. arrival of a stimulus and activation of a receptor5. information processingThe proper sequence of these steps is(a) 1, 3, 4, 5, 2.(b) 4, 5, 3, 1, 2.(c) 4, 1, 5, 2, 3.(d) 4, 3, 1, 5, 2.(e) 3, 1, 4, 5, 2.

The contraction of flexor muscles and the relaxation of extensor muscles illustrate the principle of (a) reverberating circuitry, (b) generalized facilitation, (c) reciprocal inhibition, (d) reinforcement.

List, in sequence, the five steps involved in a neural reflex.

Polysynaptic reflexes can produce far more complicated responses than can monosynaptic reflexes because (a) the response time is quicker, (b) the response is initiated by highly sensitive receptors, (c) motor neurons carry impulses at a faster rate than do sensory neurons, (d) the interneurons involved can control several muscle groups.

What five characteristics are common to all polysynaptic reflexes?
