Question 1

What does an axon do?

Answer 1

Transmits signals/carries messages to other neurons.

Question 2

What do dendrites do?

Answer 2

Recieve signals

Question 3

What do terminal buttons do?

Answer 3

Release neurotransmitters and transmit signals to other neurons.

Question 4

What does the myelin sheath do?

Answer 4

• Insulates the axon.
• Speeds up signal transmission along the axon.

In the temporal lobe below the cerebral cortex.

Question 6

What is the hippocampus?

Answer 6

A brain structure that plays a critical role in memory.

Question 19

What is long-term memory?

Answer 19

The capacity to store information over long periods of time.

Question 20

Are medial temporal lobes required for short-term or working memory?

Answer 20

No

Question 21

Are medial temporal lobes required for converting short-term memories into long-term memories (consolidation)?

Answer 21

Yes

Question 22

Are medial temporal lobes the ultimate storage site for long-term memory of all previously acquired knowledge?

Answer 22

No

Question 23

What does the bony labyrinth receive inputs about?

Answer 23

• Position of the head in space.
• Angular acceleration of the head.

Question 24

What is the most common type of sensorineural hearing loss?

Answer 24

• Tinnitus.
• It is due to damage to cochlear hair cells.

Question 25

What is the most common type of conductive hearing loss?

Answer 25

• Otosclerosis.
• It is due to abnormal growth of the bone in the ossicles.
