Section 1 (Nervous System Fundamentals)

What is the function of sensory input in the nervous system? (p. 395)

• • To monitor changes inside and outside the body

• To activate effector organs

• To interpret sensory input

• To conduct impulses from the CNS to skeletal muscles

1. What does the term "afferent" mean in the context of the nervous system? (p. 395)

• Regulating smooth muscles, cardiac muscle, and glands

• Carrying impulses to effector organs

• • Carrying away from a center

• • Carrying impulses from sensory receptors to the CNS

What does the autonomic nervous system regulate? (p. 395)

• Skeletal muscles

• Smooth muscles, cardiac muscle, and glands

• Sensory receptors

• • Voluntary activities
