Slice B depicts which feature among the options?

• A. Inferior portion
• B. Anterior horn
• C. Third ventricle
• D. Sylvian fissure

Answer: (B)

In brain slices, recognizing the shape and location of ventricular parts is the key. The feature shown is the anterior horn of the lateral ventricle. It’s the forward-front extension of the ventricle that reaches into the frontal lobe, appearing as a curved, anterior portion near the caudate head. This distinguishes it from the other structures: the third ventricle sits along the midline between the thalami as a narrow slit; the Sylvian fissure is the large lateral sulcus separating frontal/parietal from temporal lobes and appears as a groove rather than a ventricle extension; and an inferior or temporal horn would project lower and toward the temporal region, not as a prominent forward extension in the frontal area.
