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

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.

What five characteristics are common to all polysynaptic reflexes?

Compare and contrast flexor and crossed-extensor reflexes.

Bowel and urinary bladder control involve spinal reflex arcs that are located in the sacral region of the spinal cord. In both instances, two sphincter muscles—an inner sphincter of smooth muscle and an outer sphincter of skeletal muscle—control the passage of wastes (feces and urine) out of the body. How would a transection of the spinal cord at the L₁ segment level affect an individual's bowel and bladder control?

What is the homeostatic value of flexor reflexes?
