13. The Peripheral Nervous System

What is the homeostatic value of flexor reflexes?

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 clinical information can be gained by conducting somatic reflex tests?

What is the structural and functional relationship between spinal nerves, skeletal muscles, and dermatomes?
