Multiple Choice

Which of the following is the primary functional difference between the somatic nervous system (SNS) and autonomic nervous system (ANS)?

The SNS controls glands, the ANS controls muscles.

The SNS controls involuntary muscle, the ANS controls voluntary muscle.

The SNS controls voluntary muscle, the ANS controls involuntary muscle.

The SNS sends signals from the CNS, the ANS sends signals from the PNS.

Verified step by step guidance

Understand the basic functions of the nervous system: The nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The PNS is further divided into the somatic nervous system (SNS) and the autonomic nervous system (ANS).

Identify the role of the somatic nervous system (SNS): The SNS is responsible for voluntary movements and the control of skeletal muscles. It involves conscious control, such as moving your arm or walking.

Identify the role of the autonomic nervous system (ANS): The ANS regulates involuntary functions, such as heart rate, digestion, and respiratory rate. It controls smooth muscles, cardiac muscles, and glands without conscious effort.

Compare the control of muscle types: The SNS controls voluntary muscles, which are primarily skeletal muscles. In contrast, the ANS controls involuntary muscles, which include smooth and cardiac muscles.

Evaluate the options given in the problem: The correct distinction is that the SNS controls voluntary muscle, while the ANS controls involuntary muscle. This aligns with the roles of each system as described in the previous steps.

Open Question

Tiffany, a 21-year-old college student, is having trouble sleeping, cries frequently, and has recurrent thoughts of suicide. An antidepressant is prescribed. Like many such drugs, this antidepressant has anticholinergic side effects. What side effects might Tiffany experience in the first week of treatment?

Open Question

Mr. Johnson suffers from urinary retention and a hypoactive urinary bladder. Bethanechol, a drug that mimics acetylcholine's autonomic effects, is prescribed to manage his problem. First explain the rationale for prescribing bethanechol, and then predict which of the following adverse effects Mr. Johnson might experience while taking this drug (select all that apply): dizziness, low blood pressure, deficient tear formation, wheezing, increased mucus production in bronchi, deficient salivation, diarrhea, cramping, excessive sweating, undesirable erection of penis.

Open Question

A 32-year-old woman complains of intermittent aching pains in the medial two fingers of both hands. During such episodes, the fingers become blanched and then blue. Her history is taken, and it is noted that she is a heavy smoker. The physician advises her that she must stop smoking and states that she will not prescribe any medication until the patient has discontinued smoking for a month. What is this patient's condition, and why was she told to stop smoking?
