Lesson 2 Interim Review

Which part of the nervous system processes and interprets information?

• Sensory neurons

• Motor neurons

• Central nervous system (CNS)

• Peripheral nervous system (PNS)

What is the primary role of sensory neurons?

• Send signals from the brain to muscles

• Process input and generate a response

• Transmit information from sensory receptors to the CNS

• Interpret data in the brain

Which test is best for identifying abnormalities such as lesions or tumors in the brain?

• Nerve conduction velocity test

• CT scan or MRI

• Electromyography (EMG)

• Spinal tap (cerebrospinal fluid test)

What symptoms indicate motor neuron damage?

• Muscle weakness, spasms, and abnormal nerve conduction velocity

• Numbness and tingling

• Decreased sensation

• Difficulty interpreting visual information

• Spinal tap

• Electromyography (EMG)

• Nerve conduction velocity test

What does cerebrospinal fluid (CSF) analysis detect?

• Tumors or lesions

• Nerve damage in muscles
