question 22
1 pts
the groove between the frontal and parietal lobes of the cerebral cortex is the
longitudinal fissure.
central sulcus.
lateral fissure.
parietooccipital fissure.
question 23
1 pts
the ____ consists of several structures that lie beneath the thalamus and form the floor of
the third ventricle and the lower part of its lateral walls.
hypothalamus
pons
cerebellum
diencephalon
question 24
1 pts
the second largest part of the brain, located just below the posterior portion of the cerebrum,
is the
midbrain.
medulla oblongata.
cortex.
cerebellum.

Explanation:

• Question 22: The central sulcus is the groove that separates the frontal lobe from the parietal lobe in the cerebral cortex. The longitudinal fissure separates the two cerebral hemispheres, the lateral fissure separates the temporal lobe from the frontal and parietal lobes, and the parieto - occipital fissure separates the parietal and occipital lobes.
• Question 23: The hypothalamus is located beneath the thalamus, forms the floor of the third ventricle and part of its lateral walls. The pons is part of the brainstem, the cerebellum is involved in motor control, and the diencephalon is a broader region that includes the thalamus and hypothalamus.
• Question 24: The cerebellum is the second - largest part of the brain (after the cerebrum) and is located below the posterior part of the cerebrum. The midbrain is part of the brainstem, the medulla oblongata is also part of the brainstem, and the cortex is the outer layer of the brain (not a distinct part in terms of size ranking like this).

Answer:

• Question 22: central sulcus
• Question 23: hypothalamus
• Question 24: cerebellum
