Introduction to the Autonomic Nervous System Practice Problems

The autonomic nervous system controls the functions of the body's internal organs, such as heart rate, blood pressure, digestion, and body temperature. Which of the following is not a disorder of the autonomic nervous system?

Multiple system atrophy (MSA) is a rare, degenerative neurological disorder that affects involuntary (autonomic) functions, including blood pressure and motor control of the body. Which of the following symptoms is more commonly associated with the cerebellar type of MSA?

Emily, a 24-year-old medical student, is volunteering at a local hospital. She experienced sudden dizziness while observing a surgical procedure. The sight of blood made her collapse to the ground. She quickly regained consciousness within a minute but felt weak and disoriented afterward. What type of autonomous disorder is Emily likely experiencing in this situation?

The autonomic nervous system maintains the:

Which of the following cranial nerves is incorrectly matched with the parasympathetic ganglion it synapses on?

Which of the following statements concerning the autonomic tone is false?

Where is the primary center of control in the visceral motor system?

Identify the most common and disabling form of senile dementia. 

In the sympathetic division of the autonomic nervous system, where are the cell bodies of preganglionic neurons primarily located?

Identify the ganglia that innervate the chest's organs and tissues, such as the heart, lungs, and blood vessels:

Which of the following ganglia innervates the rectum, sigmoid colon, descending colon, and other pelvic organs?

Which of the following is NOT a typical response of the body during the "fight or flight" response?

Which of the following ganglia provides sympathetic innervation to the abdominal organs, including the stomach, liver, spleen, pancreas, and kidneys?

The pupillary reflex, which leads to the dilation of the pupils in darkness, is mediated by:

The inferior mesenteric ganglion provides sympathetic innervation to various organs in the lower part of the abdominopelvic cavity. Which organs are included in its innervation?

As the enteric nervous system (ENS) comprises a complex network of neurons and neurotransmitters that may operate independently from the central nervous system (CNS), it is commonly referred to as:

The white and gray rami communicantes are named based on their color, which reflects the myelination status of the nerve fibers they contain. The white rami communicantes appear white because they contain:

Which of the following components of the enteric nervous system controls the motility and contractions of the gastrointestinal tract?

Which of the following is an effect of parasympathetic activity on the cardiovascular system?

The effect of acetylcholine (ACh) released by sympathetic preganglionic neurons on ganglionic neurons is:

Muscarinic receptors are primarily found at :

Which of the following ganglia has postganglionic fibers that innervate the stomach, liver, gallbladder, pancreas, and spleen?

When adrenal medullae release epinephrine and norepinephrine into the bloodstream, the effects last longer primarily because:

Parasympathetic preganglionic fibers leaving the brain are associated with which cranial nerve?

Which of the following plexuses innervates the urinary bladder and the reproductive organs?

When a vital organ receives information from both the parasympathetic and sympathetic systems, it is referred to as:

What effect does damage to the anterior roots of the cervical spinal nerves have on sympathetic function in the cervical region?

Stimulation of the reticular activating system (RAS) leads to:

How will the activation of the "fight or flight" response affect the diameter of the peripheral blood vessels?

In response to a potentially threatening situation, sympathetic activation likely results in:

How does adrenaline (epinephrine) affect blood pressure during emotional shock?

Which of the following is controlled by the somatic nervous system?

Junior was working at a construction site when he accidentally stepped on a protruding nail on the floor. What kind of reflex would act to protect the foot that has stepped on the nail by shifting his body weight on his other foot:

The following statements describe adrenergic receptors, except:

The release of epinephrine from the adrenal medulla is regulated by:

The following includes the functions of the autonomic nervous system, except:

The autonomic and endocrine nervous systems are both controlled by a reticular formation which is situated in:

Which of the following accurately describes the main pathways of the autonomic nervous system?  

Which type of motor neurons innervate smooth muscle, cardiac muscle, glands, and adipose tissue?
