The dorsal horn of the spinal cord contains: - cell bodies of sensory neurons - interneurons receiving sensory input - visceral motor neurons - somatic motor neurons 2. The fluid contained in the fourth ventricle is circulated (moved around) by the activity of: - oligodendrocytes - arachnoid granulations - astrocytes - ependymal cells 3. Neurons in the postcentral gyrus are: - interneurons - motor neurons - Schwann cells - sensory neurons 4. The gyrus anterior to the arrows contains the: - primary visual cortex - primary auditory cortex - primary somatosensory cortex 5. Which of the following is not true about reflexes? - reflexes can be acquired/learned - we are born with some reflexes (inborn) - reflexes are limited to one side of the body - all reflexes have the same five components 6. Effectors of the autonomic nervous system respond to: - epinephrine exclusively - none of the choices listed here - epinephrine or acetylcholine - acetylcholine exclusively 7. Paravertebral ganglia are associated with the: - sympathetic division - parasympathetic division - somatic motor division

19. Dendrites: A) carry impulses from ganglia to organs B) are found only in the peripheral nervous system C) carry impulses toward a nerve cell body D) are solely responsible for sodium flux 20. The primary function of the spinal cord is: A) simple reflexes B) to help integrate incoming and outgoing signals to and from the brain C) to act as a link between the brain and the body D) all are correct 21. The autonomic nervous system: A) regulates only organs on the left side of the body B) has preganglionic but no postganglionic fibers C) is only part of the central nervous system D) has cell bodies in both the spinal cord and in ganglia 22. The cell bodies of the postganglionic neurons of the sympathetic system lie in the: A) chain of ganglia running alongside the spinal cord B) gray matter of the brain C) the gray matter of the spinal cord D) ventral root ganglia 23. Which type of neuron conducts information away from the central nervous system out to effectors in the periphery? A) sensory neuron B) interneuron C) motor neuron 24. Which type of neuron conducts information from receptors in the periphery to the central nervous system? A) sensory neuron B) interneuron C) motor neuron 25. The portion of the neuron that conducts impulses away from the cell body is the: A) dendrite B) axon C) peripheral process

Interneurons Neurons that connect sensory and motor neurons Part 2: Copy the number for each question and indicate whether each of the following statements is true or false. 1. The cerebellum is the largest part of the brain. False 2. The pons is located below the medulla oblongata. True 3. The hypothalamus controls urges such as thirst and hunger. True 4. The corpus callosum controls most thinking and reasoning processes. True 5. Motor neurons will carry an impulse toward the central nervous system. True 6. The dorsal root of the spine's vertebrae has sensory neurons passing through. True 7. The hypothalamus produces several hormones that are stored in the pituitary gland. True 8. The hypothalamus usually involves the peripheral nerves and the spinal cord. False 9. A reflex lobe of the brain controls vision. False 10. The temporal lobe of the brain controls hearing. True 11. The frontal lobe controls respiration. False 12. The autonomic nervous system is part of the sympathetic nervous system. True 13. The hindbrain connects with the forebrain. False 14. The midbrain connects the nervous system.
