Question 1
Spina bifida causes problems with the structure that develops into the _____.
-
Aspinal cord
-
Bsolar plexus
-
Ceye
-
Dbiceps femoris
spinal cord
Spina bifida occurs when the vertebrae of the spinal column don't properly enclose the neural tube, the structure that develops into the spinal cord.
Question 2
Which of the following comprise the central nervous system (CNS)?
-
ABrain and spinal cord
-
BPain and pressure receptors
-
CVisceral and somatic nerves
-
DSensory and motor nerves
Brain and spinal cord
The brain and spinal cord process the information they receive from the peripheral nervous system and, in response, send signals to muscles and glands.
Question 3
What is the cause of shingles?
-
AAn STD.
-
BThe chickenpox virus.
-
CBotox injections.
-
DAn HIV infection.
The chickenpox virus.
The chicken pox virus hides out in the nervous system. As immune system function declines with age, the virus may become active and travel along the nerves in which it was hidden.
Question 4
The light receptors (photoreceptors) of the eye are found in the _____.
-
Asclera
-
Bconjunctivia
-
Cchroroid
-
Dretina
retina
While all of these are part of the eye, it is the retina where the photoreceptors (rods and cones) are found.
Question 5
What name is given to the fluid that cushions the components of the central nervous system?
-
ACerebrospinal fluid
-
BSynovial fluid
-
CAqueous humor
-
DVitreous humor
Cerebrospinal fluid
The brain (cerebro-) and spinal cord are the two main components of the central nervous system.
Question 6
Which neurotransmitter is also secreted by the adrenal glands?
-
AAdrenaline
-
BGABA
-
CGlutamate
-
DATP
Adrenaline
Adrenaline and adrenal have the same root.
Question 7
Which of the following is a reflex?
-
AFinger tapping when nervous
-
BGetting angry
-
CChewing food
-
DDilation and constriction of the pupils
Dilation and constriction of the pupils
Reflexes are involuntary responses to a stimulus.
Question 8
Auditory receptors are found in the _____.
-
Aear
-
Bnose
-
Ceye
-
Dmouth
ear
The word "auditory" refers to hearing.
Question 9
Which of these terms applies to paralysis of all four limbs?
-
AParaplegia
-
BQuadriplegia
-
CHemiplegia
-
DHyperplegia
Quadriplegia
The prefiix "quadra-" refers to the four limbs of the human body.
Question 10
Which of the following is the single longest nerve in the body?
-
ASolar plexus
-
BUlnar nerve
-
CSciatic nerve
-
DRadial nevre
Sciatic nerve
The sciatic nerve runs from the lower region of the spinal cord, past the buttocks, down the back of the leg to the foot. Now you know why sciatica is so painful.
Question 11
What is meningitis?
-
ACancer of the meninges
-
BShrinkage of the meninges
-
CInflammation of the meninges
-
DAtrophy of the meninges
Inflammation of the meninges
The suffix "-itis" means inflammation. So meningitis is inflammation of the meninges, the tissues that overlay and protect the brain and spinal cord.
Question 12
The descending tracts of the spinal cord carry information from _____.
-
Athe brain to the spinal cord
-
Bpain receptors to the spinal cord
-
Cthe spinal cord to the brain
-
Dthe eyes to the brain
the brain to the spinal cord
The brain sends messages to the spinal cord, located beneath the brain, to regions located below the location of the brain.
Question 13
What causes the symptoms of multiple sclerosis?
-
AExcessive carbohydrate intake.
-
BExcessive neurotransmitter release.
-
CDegeneration of the sheath that covers the neurons of the central system and the replacement of this sheath with scar tissue.
-
DMultiple sclerosis is caused by obesity.
Degeneration of the sheath that covers the neurons of the central system and the replacement of this sheath with scar tissue.
Degeneration of the sheath that covers neurons impairs nerve impulse conduction leading to the symptoms of multiple sclerosis.
Question 14
What is neuralgia?
-
ANight blindness
-
BNumbness
-
CBone pain
-
DNerve pain
Nerve pain
The prefix "neur-" refers to nerves and the suffix "-algia" refers to pain.
Question 15
Olfactory receptors are found in the _____.
-
Aeye
-
Bnose
-
Cear
-
Dmouth
nose
Olfaction is the sense of smell and humans smell with their noses. :)
Question 16
How does caffeine make you feel energetic?
-
ACaffeine stimulates the nervous system.
-
BCaffeine provides both calories and stimulates the nervous system.
-
CCaffeine inhibits nerve impulses.
-
DCaffeine provides the body with calories.
Caffeine stimulates the nervous system.
Caffeine does not contain calories. It makes you feel energized by stimulating the nervous system without actually providing the body with any energy.
Question 17
Which famous physicist suffered from amyotrophic lateral sclerosis (ALS)?
-
AAlbert Einstein
-
BNicolaus Copernicus
-
CIsaac Newton
-
DStephen Hawking
Stephen Hawking
Dr. Hawking suffered from ALS.
Question 18
Why does food taste bland when you have a cold?
-
AMuch of what we perceive as taste is actually smell.
-
BThe lack of desire to eat when ill causes food to taste bad.
-
CA cold increases the rate at which taste buds die and replacement taste buds are formed at a slower than usual rate.
-
DA cold causes taste receptors to malfunction.
Much of what we perceive as taste is actually smell.
The stuffed nose that accompanies a cold blocks the odor (olfactory) receptors of the nose thus blunting the taste of food.
Question 19
There are sensory neurons that conduct impulses from the peripheral nervous system to the central nervous system. There are motor neurons that conduct impulses from the central nervous system to muscles and glands. What kind of neurons are found between sensory and motor neurons?
-
AIntraneurons
-
BParaneurons
-
CInterneurons
-
DEctoneurons
Interneurons
In this context, the prefix "inter-"means between.
Question 20

-
Amedulla oblongata
-
Bcerebrum
-
Ccerebellum
-
Dhypothalamus
cerebrum
The cerebrum, which consists of five lobes, is the largest part of the brain.
