Question text
What is the importance of the ventral pathway, and it occurs through which lobe?
a.
Identification of objects; frontal cortex
b.
Recognition of objects; occipitoparietal cortex
c.
Recognition and identification of objects; temporal cortex
d.
Identification and recognition of objects; occipital cortex
Answer
,The correct answer is:
c. Recognition and identification of objects; temporal cortex
The ventral pathway, also known as the "what" pathway, is crucial for the recognition
and identification of objects. It extends from the occipital lobe to the temporal cortex,
enabling the processing of visual information to determine what objects are.

Question text
A 50-year-old male presented with a peculiar sensory deficit below his nose following a recent illness.
Upon examination, it was revealed that the patient's illness had destroyed all myelinated somatosensory
axons below his nose while sparing the unmyelinated axons.
Which of the following sensory modality or modalities would likely be impaired in the patient based on
the provided case study?
a.
Conscious perception of touch
b.
Ability to feel the temperature
c.
Unconscious perception of touch
d.
Subconscious perception of touch
Answer
, The correct answer is:
a. Conscious perception of touch
Myelinated somatosensory axons are primarily responsible for the transmission of fine
touch, pressure, and proprioceptive information. Since the patient's illness destroyed all
myelinated somatosensory axons below his nose, the conscious perception of touch
would likely be impaired. Unmyelinated axons, which were spared, are typically involved
in the transmission of pain and temperature sensations. Therefore, the patient's ability
to feel temperature would be less likely to be impaired.
