Question
8. Which of the choices below describes the ANS? A) motor fibers that conduct nerve impulses from the CNS to smooth muscle, cardiac muscle, and glands B) motor fibers that conduct nerve impulses from the CNS to skeletal muscles C) sensory neurons that convey information from somatic receptors in the head; body wall, and limbs and from receptors from the special senses of vision, hearing, taste, and smell to the CNS D) sensory and motor neurons that supply the digestive tract What are ciliated CNS neuroglia that play an active role in moving the cerebrospinal fluid called? 9. A) ependymal cells B) Schwann cells C) oligodendrocytes D) astrocytes 10. The part of a neuron that conducts impulses away from its cell body is called a(n) A) axon B) dendrite C) neurolemma D) Schwann cell 11. That part of the nervous system that is voluntary and conducts impulses from the CNS to the skeletal muscles is thenervous system. 12. The brain stem consists of the A) cerebrum, pons, midbrain, and medulla B) midbrain, medulla, and pons C) pons, medulla, cerebellum, and midbrain D) midbrain only 13. The primary auditory cortex is located in the A) prefrontal lobe B) frontal lobe C) temporal lobe D) parietal lobe 14. What cells line the ventricles of the brain? A) ependymal cells B) neurons C) epithelial cells D) astrocytesExplanation / Answer
8. Option A is the correct answer. There are two types of peripheral nervous system (PNS). Somatic nervous system amd autonomic nervous system. Somatic nervous system controls the voluntry while ANS controls the involuntry function like control of breathing, heart beat, digestive processes and glandular secretions
9. Option A is the correct answer. Ependymal cells have cilia which make cerebrospinal fluid movable.
10. Option A is the correct answer. There are three main parts of the neuron. Cell body, axon and dendrites. Axon is the middle long portion which carry the impulses from cell body to the dendrites.
11. Somatic. Somatic nervous system is the part of peripheral nervous system which control voluntry function like muscular movement
12. Option B is the correct answer. The brain stem is the central trunk of the mammalian brain, consisting of the medulla oblongata, pons, and midbrain, and continuing downwards to form the spinal cord.
13. Option C is the correct answer. The primary auditory cortex is located in the temporal lobe of the brain and responsible for processing of auditory information.
14. Option A is the correct answer.
