All of the following characterize the ANS except (a) a two-neuron efferent chain, (b) presence of neuron cell bodies in the CNS, (c) presence of neuron cell bodies in the ganglia, (d) innervations of skeletal muscles.

Expert Solution & Answer

Summary Introduction

To determine:

All of the following characterize the Autonomic Nervous System (ANS) except

a two-neuron efferent chain,
presence of neuron cell bodies in the CNS,
presence of neuron cell bodies in the ganglia,
innervation of skeletal muscles.

Answer to Problem 1MC

Correct answer:

(d) Innervation of skeletal muscles

Explanation for the correct answer:

Option (d) is given as innervations of skeletal muscles. The ANS (autonomic nervous system) is classified as a portion of the PNS (peripheral nervous system) that provides smooth muscles and glands and influences the activity of the internal organs. It is a unique system that needs a sequential two-neuron efferent pathway. It consists of cell bodies and these bodies have neurons in the CNS (central nervous system) and ganglia. Hence, option (d) is the correct option.

Explanation of Solution

Explanation for the incorrect answers:

Option (a) is given as a two-neuron efferent chain. The autonomic nervous system (ANS) is unique as it requires a sequential two-neuron efferent pathway; the preganglionic neuron must first cross a synapse onto a postganglionic neuron before innervating the target organ. Hence, option (a) is an incorrect option.

Option (b) is given as a presence of neuron cell bodies in the CNS. Neuron cell bodies are a junction between autonomic nerves originating from the central nervous system and autonomic nerves innervating their target organs in the periphery. Hence, option (b) is an incorrect option.

Option (c) is given as a presence of neuron cell bodies in the ganglia. In ganglia, cell bodies of afferent nerves (input nerve fibers) and efferent nerves (output/motor nerve fibers), or axons are present. Ganglia is located in the autonomic nervous system and sensory system. Hence, option (c) is an incorrect option.

Conclusion

ANS is characterized by a two-neuron efferent chain, presence of neuron cell bodies in the CNS and the ganglia.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.

Hence, option (a) is an incorrect option.

Option (b) is given as a presence of neuron cell bodies in the CNS. Neuron cell bodies are a junction between autonomic nerves originating from the central nervous system and autonomic nerves innervating their target organs in the periphery. Hence, option (b) is an incorrect option.

Option (c) is given as a presence of neuron cell bodies in the ganglia. In ganglia, cell bodies of afferent nerves (input nerve fibers) and efferent nerves (output/motor nerve fibers), or axons are present. Ganglia is located in the autonomic nervous system and sensory system. Hence, option (c) is an incorrect option.
