○ true
○ false
68 multiple choice 1 point
the olfactory tract:
○ projects to the primary olfactory cortex and to the limbic system
○ conducts impulses to the epithalamus
○ contains only motor neurons
○ receives information from the taste buds
69 multiple choice 1 point
which of the below structures senses dynamic equilibrium?
○ macule of the vestibule
○ semicircular canals
○ organ of corti
○ cochlea

Explanation:

Question 1 (Farsightedness statement)

Farsightedness (hyperopia) occurs when the eyeball is too short or the lens is too flat (not too long or too curved; myopia is eyeball too long or lens too curved). So the statement is false.

• The olfactory tract projects to the primary olfactory cortex (for smell perception) and the limbic system (for emotional/ memory - related smell responses).
• It does not conduct to the epithalamus, contains sensory (not motor) neurons, and taste buds are for taste (not related to olfactory tract).

• Semicircular canals detect dynamic equilibrium (movement, rotation).
• Macule of vestibule detects static equilibrium (head position relative to gravity).
• Organ of Corti and cochlea are for hearing.

Answer:

false
