Which pathway carries sensory information toward the central nervous system (CNS)? a. Ascending c. b. Descending Somatic d. Efferent ANS: A Peripheral nerve pathways can be afferent (ascending) pathways that carry sensory impulses toward the CNS. The remaining options do not carry sensory information to the CNS. PTS: 1 REF: Page 448 2. Which type of axon transmits a nerve impulse at the highest rate? a. Large nonmyelinated c. b. Large myelinated Small nonmyelinated d. Small myelinated ANS: B If the myelin layer is tightly wrapped many times around the axon and is forming the nodes of Ranvier, then conduction velocity increases and the neuron is referred to as myelinated. The increased diameter of the myelinated axons allows for the transmission of impulses at a faster rate. The other options do not affect nervous impulse transmission rates. PTS: 1 REF: Pages 4N4U 8-R4S5I0NGTB.COM 3. Which nerves are capable of regeneration? a. Nerves within the brain and spinal cord b. Peripheral nerves that are cut or severed c. Myelinated nerves in the peripheral nervous system d. Unmyelinated nerves of the peripheral nervous system ANS: C Nerve regeneration is limited to only myelinated fibers and generally occurs only in the peripheral nervous system. PTS: 1 REF: Pages 450-451 4. The neurotransmitter, norepinephrine, is secreted in the: a. Somatic nervous system b. Parasympathetic preganglion ANS: C PTS: 1 c. Sympathetic postganglion d. Parasympathetic postganglion Most postganglionic sympathetic fibers release norepinephrine (adrenaline). The remaining options do not reflect the correct site of norepinephrine secretion. REF: Pages 473-474 5. Both oligodendroglia and Schwann cells share the ability to: [Show More]
