Question 2

All of the following drugs are stimulants EXCEPT
A) nicotine.
B) cocaine.
C) caffeine.
D) ecstasy.
E) alcohol.

Accepted Answer

Alcohol is a depressant, not a stimulant. The other choices (nicotine, cocaine, caffeine, ecstasy) are all stimulants that increase activity in the nervous system.

A) red, green, blue
B) blue, yellow, red
C) yellow, orange, brown

Question 6

The boundary between the middle ear and the inner ear is the
A) eardrum.
B) oval window.
C) cochlea.
D) stirrup.
E) auditory canal.

Accepted Answer

The oval window is the boundary between the middle ear and the inner ear. It separates the air-filled middle ear space from the fluid-filled inner ear space. The vibrations of the eardrum are transferred to the oval window by the three tiny bones of the middle ear (malleus, incus, and stapes), which in turn set the fluid inside the cochlea in motion.

Question 9

The part of the ear actually responsible for hearing is the
A) hammer, anvil, and stirrup.
B) cochlea.
C) vestibular apparatus.
D) organ of Corti.
E) combination of the organ of Corti and the vestibular apparatus.

Accepted Answer

The organ of Corti is a structure within the cochlea that contains sensory cells responsible for detecting sound waves and converting them into neural signals that are sent to the brain. The hammer, anvil, and stirrup are parts of the middle ear that transmit vibrations from the eardrum to the cochlea. The vestibular apparatus is responsible for detecting changes in head movement and orientation, but not specifically for hearing. Therefore, the best choice is D) organ of Corti.

Question 10

Which of the following is NOT a structure of the middle ear?
A) eardrum
B) anvil
C) hammer
D) cochlea
E) all of these are structures of the middle ear

Accepted Answer

The cochlea is not part of the middle ear, it is part of the inner ear. The eardrum, anvil, and hammer are all structures of the middle ear.

Question 11

Match the neurotransmitter with its description.
a.serotonin
b.epinephrine
c.dopamine
d.acetylcholine
e.endorphins
f.none of these neurotransmittes match the description
-a decrease in this neurotransmitter causes attention deficit hyperactivity disorder

Accepted Answer

The answer of Match the neurotransmitter with its description.
a.serotonin
b.epinephrine
c.dopamine
d.acetylcholine
e.endorphins
f.none of...

Question 12

When the myelin sheath is destroyed,like in MS patients,the resulting disruption in information flow can lead to all of the following EXCEPT
A) muscle weakness.
B) severe hyperactivity.
C) numbness.
D) tremors.
E) visual problems.

Accepted Answer

Severe hyperactivity is not typically associated with the disruption in information flow caused by the destruction of the myelin sheath. The other options are all symptoms commonly seen in MS patients.

Question 13

All of the following structures of the ear pass on vibrations from sounds except the
A) hammer
B) eardrum
C) oval window
D) organ of Corti
E) cochlea

Accepted Answer

The organ of Corti is responsible for transducing (converting) the vibrations from the sound into electrical signals that the brain can interpret as sound. The other structures listed (hammer, eardrum, oval window, and cochlea) are all involved in transmitting or amplifying the vibrations of sound waves.

A) chemoreceptors
B) mechanoreceptors
C) proprioreceptors
D) photoreceptors
E) more than one of these

Accepted Answer

Mechanoreceptors, specifically hair cells in the cochlea of the inner ear, are responsible for detecting sound waves and creating the action potential that is transmitted to the brain, where it is perceived as sound.
