Fill in the blank. The main lobes of the cerebral
cortex include the temporal lobe, the parietal lobe, the occipital lobe, and the
blank. (A) Anterior lobe, (B) spinal lobe,
(C) auditory lobe, (D) frontal lobe, (E) adrenal lobe.
This question asks us about the
main lobes of the cerebral cortex. So to answer the question, let’s
recall what the cerebral cortex is and review what we know about its structure.
The cerebral cortex is the outer
layer of our cerebrum that has a characteristic wrinkled appearance. It consists of two identical
hemispheres, left and right, that are separated by a fissure. Scientists traditionally divide
each hemisphere into four lobes that are created by fissures and grooves.
The frontal lobe is extremely
important for executive functioning including cognition, reasoning, planning, and
voluntary movement.
The parietal lobe is especially
important in sensory integration of sensory information, such as touch, temperature,
pain, and pressure.
The occipital lobe is mostly
responsible for vision, such as processing information from the eyes and then
interpreting this information into the images that create our perception of the
world.
The temporal lobe is responsible
for processing auditory information. It also contains regions
responsible for our comprehension of language and many aspects of our memory.
After recalling the four different
lobes of the cerebral cortex, we’re able to compare the list found in the question
with the answer choices to identify which lobe is missing from the list in the
question. Notice that the anterior lobe,
spinal lobe, auditory lobe, and adrenal lobe are not recognized structures in the
cerebral cortex. However, the frontal lobe is.
With this information, we’re now
able to complete the sentence in the question. So, the completed sentence should
read as “The main lobes of the cerebral cortex include the temporal lobe, the
parietal lobe, the occipital lobe, and the frontal lobe.”
