Understanding Nervous System Disorders

What is the primary function of the peroneal nerve in the human body?

• To control the muscles in the arm

• To transmit signals to the muscles in the foot

• To regulate heart rate

• To manage digestion

Which diagnostic test would be most appropriate to determine if there is a problem with the myelin sheath of neurons?

• Electromyography (EMG)

• Nerve Conduction Velocity Test

• Analysis of Cerebrospinal Fluid (CSF)

• MRI Scan

If a patient shows muscle weakness and decreased reflexes, what type of nerve damage might they be experiencing?

• Sensory nerve damage

• Motor nerve damage

• Autonomic nerve damage

• Central nerve damage

How can a neurologist use the results of a nerve conduction velocity test to diagnose a neurological disorder?

• By measuring the electrical activity in muscles

• By assessing the speed of electrical signals through nerves

• By analyzing the chemical composition of cerebrospinal fluid

• By creating a three-dimensional image of the brain

What might abnormal electrical activity during an EMG test indicate about a patient's nervous system?

• A problem with the brain's structure

• A muscle or nerve problem

• An infection in the cerebrospinal fluid

• A malfunction in the digestive system

Which of the following symptoms would most likely indicate sensory nerve damage?

• Muscle shrinkage

• Decreased reflexes

• Tingling or numbness

• Muscle spasms

What is the role of cerebrospinal fluid in the nervous system?

• To transmit electrical signals between neurons

• To deliver nutrients and cushion the brain and spinal cord

• To regulate blood flow to the brain

• To control muscle contractions

Which imaging technique would be most useful for detecting brain lesions?

• Electromyography (EMG)

• Nerve Conduction Velocity Test

• CT Scan

• Analysis of Cerebrospinal Fluid (CSF)

How does the nervous system allow our bodies to interact with the outside world?

• By controlling the digestive system

• By generating, sending, and processing signals

• By regulating blood pressure

• By producing hormones

What can patient signs and symptoms tell us about what’s happening in the human body?

• They provide information about the patient's diet

• They help identify potential nervous system dysfunctions

• They indicate the patient's emotional state

• They reveal the patient's exercise habits
