When you touch a hot surface, which description correctly distinguishes the incoming signal from the command that withdraws your hand?

  1. A

    Motor (efferent) signals travel toward the spinal cord, and sensory (afferent) signals travel to the muscles.

  2. B

    Sensory (afferent) signals travel toward the CNS, and motor (efferent) commands travel to the muscles.

  3. C

    Both sensory and motor signals travel from the spinal cord toward receptors.

  4. D

    Sensory signals travel from the CNS to muscles, while motor signals travel from receptors to the CNS.

  2. B

    Both sensory and motor fibers enter through dorsal roots and leave through ventral roots.

  3. C

    Sensory fibers enter through dorsal roots, and motor fibers leave through ventral roots.

A body function is involuntary and involves smooth muscle, cardiac muscle, or glands. Which motor division is most directly associated with regulating it?

  1. A

    The somatic nervous system, because it regulates involuntary activity in smooth muscle and glands.

  2. B

    The sensory division, because it sends commands from the CNS to muscles and glands.

  3. C

    The sympathetic system alone, because the autonomic nervous system does not include other divisions.

  4. D

    The autonomic nervous system, because it regulates involuntary functions through connections to smooth muscle, cardiac muscle, and glands.
