A splanchnic nerve in the sympathetic division of the ANS

a. connects neighboring sympathetic trunk ganglia.
b. controls parasympathetic functions in the thoracic cavity.
c. is formed by preganglionic axons that extend to prevertebral ganglia.
d. travels through parasympathetic pathways in the head.

Expert Solution & Answer

Summary Introduction

Introduction:

The motor component of the ANS (autonomic nervous system) is divided into the sympathetic division and the parasympathetic division. The sympathetic division is complex anatomically then the parasympathetic one. Sympathetic division is also called as the thoracolumbar division.

Answer to Problem 1DYKB

Correct answer:

In the sympathetic division of ANS, a splanchnic nerve is formed by the axons (preganglionic) and which extends till the prevertebral ganglia. Therefore, option c. is correct.

Explanation of Solution

Reason for the correct statement:

Option c. is given as “is formed by preganglionic axons that extend to prevertebral ganglia”. The splanchnic nerves of the sympathetic division run anteriorly from the trunk (sympathetic) to most of the pelvic and abdominal viscera. These nerves (splanchnic) possess the preganglionic axons, which begins from the trunk ganglia and reaches to the aortic wall’s prevertebral ganglia. Hence, the splanchnic nerve is formed by the axons and extends till the prevertebral ganglia.

Hence, option c. is correct.

Reasons for incorrect statements:

Option a. is given as “connects neighboring sympathetic trunk ganglia”. The splanchnic nerve does not connect the neighboring ganglia. Hence, option a. is incorrect.

Option b. is given as “connects parasympathetic functions in the thoracic cavity”. The parasympathetic preganglionic axons are branched in forming the pelvic splanchnic nerves. Hence, option b. is incorrect.

Option d. is given as “travels through parasympathetic pathways in the head”. The sympathetic splanchnic nerve runs from the trunk ganglion (sympathetic) to the prevertebral ganglia. The parasympathetic splanchnic nerves forms the pelvic splanchnic nerves. Hence, option d. is incorrect.

Hence, options a., b., and d. are incorrect.

Conclusion

The splanchnic nerves are formed by those axons, which extends to the prevertebral ganglia. Thus, from the ganglionic origins, these nerves innervate the organs of the body.

If left untreated, most HIV-infected individuals will develop AIDS. Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables. Whatparameters would you need to know to find the concentration of drug in the plasma? In the T cells?(You do not need to write out or solve any equations.)
