NGSS.HS-LS1-3

This microorganism causes the common cold. It can only multiply when inside a human host. It is so small, it can’t be seen with microscopes you will use in school, and it has the ability to mutate or change.

What type of disease agent is this microorganism?

• Virus

• Bacteria

• Fungus

• This microorganism is not a disease agent.

Does the patient have strep throat?

• Yes

• No

A patient comes to you with complaints of muscle weakness, muscle spasms, and twitches in the left arm.

-During the exam you notice no problems with sensation, and the patient reports no loss of sensation, no pain, tingling, or numbness.

-All neurological tests were normal, except for the nerve conduction velocity tests and EMG results.

Given the choices below, which structure is the most likely location of the problem?

• Sensory neurons

• Motor neurons

• Brain

• Spinal cord

Which label identifies a part of the central nervous system?

• A

• B

• C

• D

NGSS.MS-LS1-3

Which statement below describes the correct function of the central nervous system (CNS) and peripheral nervous system (PNS)?

• The PNS functions to process input from the CNS, and if necessary, triggers a response to act on the input.

• The CNS is responsible for connecting and triggering the muscle cells throughout the body to respond to stimuli.

• The CNS functions to process input from the PNS, and if necessary, triggers a response to act on the input.

• The CNS is responsible for receiving stimuli from the body’s environment and sends them as signals to the PNS.

A neurologist has information that leads her to suspect that a patient has a brain tumor.

What test should she order to confirm the diagnosis?

• A brain scan such as a CT scan or MRI

• A spinal tap to collect cerebrospinal fluid (CSF)

• Electromyography (EMG) tests

• Nerve conduction velocity tests

This microorganism causes strep throat. It can multiply without a host. It can be treated with antibiotics. It is so small, you would need to view it through a microscope at school.

What type of disease agent is this microorganism?

• Bacteria

• Virus

• Fungus

• The microorganism is not a disease agent

What functions might be affected in a patient with a tumor in the occipital lobe?

• Behavior and personality, such as planning, initiated movements, social and emotional processing, and attention.

• Sensing touch, spatial processing, language, and memory.

• Visual perception and some forms of visual short-term memory.

• Processing smell and sound, and the ability to recognize and understand words and language.

A patient comes to you with complaints of pain, tingling, and numbness in her left foot.

-The patient has no problems with movement.

-Brain scans, CSF, and EMG tests were all normal.

-Nerve conduction velocity tests were abnormal.

This information leads you to believe the problem is in the peripheral nervous system.

Given the choices below, which structure is the most likely location of the problem?

• Sensory neurons

• Brain

• Motor neurons

• Spinal cord
