Cerebrum

Part of the brain which allows thinking and voluntary movement (most sophisticated functions)

Cerebellum

Part of the brain that controls balance and coordination, refining movements

Parasympathetic

System that acts to slow down breathing and heart rate

True

Myasthenia Gravis is caused by an abnormal reaction of the body’s immune system that leads it to attack and damage receptors in the muscle

Spinal cord

Connects the 31 pairs of peripheral nerves to the brain

Reflex

An automatic response to a given stimuli

Brain

Weighs about 3 pounds in the average adult

Hypothalamus

Controls body temperature

Meninges

Made up of 3 layers that cover the brain and spinal cord, is protective

Sympathetic

System that acts to speed up heart rate and breathing

False

Damage to the brainstem is not life threatening

True

Autism appears to be related to both genetic and environmental factors

False

Each hemisphere of the brain controls the same side of the body

True

Appetite and satiety are sensed by the hypothalamus

True

The olfactory nerve senses smell

False

Alzheimer’s disease is a symptom of dementia

True

Damage to the glossopharyngeal nerve may result in dysphagia

False

The pupils constrict independently of each other

False

Multiple sclerosis affects the myelin sheaths of neurons in thee peripheral nervous system

False

Alzheimer’s disease seems to first affect the spinal cord

True

Substances called neurotransmitters are essential for neuron to neuron communication to occur

True

CSF circulates through the ventricles of the brain

True

The oculomotor nerve controls eye movement

True

Autism spectrum disorder does not have a cure

False

The general function of the parasympathetic nervous system is to speed up all of the body’s vital functions in an emergency (flight of fight)

False

A good way to test the vestibuloccochlear cranial nerve would be to have the patient identify a common smelling fragrance

Optic

Which of the following cranial nerves is considered to be part of the central nervous system

Axon

Each neuron has only one:

Myelin

The fatty substance that helps to protect the axon is called:

Sensory/afferent

The neurons that carry messages to the brain are called:

Peripheral

The nervous system that consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves is called:

Dura meter

The outermost layer of the meninges is:

Cerebrum

The frontal, parietal, temporal, and occipital lobes make up the:

Neurons

The specialized cells of the nervous system are called:

Brainstem

The respiratory center of the brain is located in the:

She may have right sided weakness

Mrs. M.Bolism is 86 years old and has a diagnosis of CVA in the left parietal lobe. Which of the following would you expect?

Cerebrovascular accident

The abbreviation for a stroke is CVA, which stands for:

Folds

Which of these features in the cerebral cortex increases the amount of information that can be processed?

Hypothalamus

This part of the brain contains the body’s set points and controls most of its physiology, including, blood pressure and hunger level:

Diencephalon

Which of the following is not part of the brainstem?

Intracranial pressure

To prevent further brain injury after TBI, medical staff must control:

Sympathetic

Mr. Jones is taking medication to keep his blood pressure low. Which autonomic nervous is this most likely to affect?

The cranial nerves

The peripheral nervous system contains:

Cerebrum

Mr. Ken Kushin was hit in the head and now has difficulty walking and maintaining his balance and writing. What part of the brain MOST LIKELY was affected?

Between the skull and arachnoid

Where would you find the dura mater?

Cerebrospinal fluid

If a needle were inserted into a ventricle in the brain, what would MOST LIKELY be withdrawn?

Peripheral nervous system

Composed of the nerves

Somatic nervous system

Controls voluntary muscle movement

Motor nervous system

Carries instructions from the brain down to the body tissues

Autonomic nervous system

Controls smooth and cardiac muscle (involuntary)

Parasympathetic nervous system

Involved in “resting and digesting”

Central nervous system

Composed of the brain and spinal cord

Sensory nervous system

Carries information about the environment up to the brain

Sympathetic nervous system

Involved in “fight or flight” response

Synapse

The tiny space between the neuron sending the signal and the cell receiving the signal

Dendrite

The portion of the neuron that receives info from the environment

Neurotransmitter

Special chemicals used to send a signal across the synapse

Axon

The portion of the neuron that generates signals sent to other cells

Myelin

A lipid (fatty) sheath that surrounds and insulates the axon
