Chapter 14: Structure and Function of the Neurologic SystemHuether: Understanding Pathophysiology, 7th EditionMULTIPLE CHOICE1. When a patient asks what the somatic nervous system controls, how should the nurse respond?It controls:a.the heart.b.the spinal cord.c.skeletal muscle.d.smooth muscle organs.ANS: CThe somatic nervous system consists of pathways that regulate voluntary motor control, the skeletal muscle system. The somatic nervous system does not control the heart; the autonomicnervous system controls the heart, the spinal cord, and the smooth muscle organs.2. A nurse is preparing to teach about nerves. Which information should the nurse include? The axon leaves the cell body at the:a.axon hillock.b.Nissl body.c.node of Ranvier.d.myelin sheath.ANS: AThe axon hillock is the cone-shaped process where the axon leaves the cell body. The Nissl body is involved in protein synthesis. Axons branch at the node of Ranvier. The myelin sheathcovers the entire membrane.3. When a student asks in which region of the neuron do nerve impulses travel the fastest, how should the nurse respond? The:a.large axon.b.axon hillock.c.cell body.d.dendrites.ANS: ALarge axons transmit impulses at a faster rate than cell bodies. The axon hillock has a low threshold level. The dendrites carry impulses toward the cell body but not as quickly as large axons.4. A neurologist is teaching
