pons

cerebellum

cerebrum

medulla oblongata

Explanation:

🆕 New Concept Discovered: Major Structures of the Human Brain
Identifying key regions and their functions.

Step 1: Analyze the diagram and arrow location

The diagram shows a sagittal (side-view) cross-section of the human brain.

• The large, pink, folded upper region is the cerebrum.
• The striped, leaf-like structure at the lower back is the cerebellum.
• The central stalk extending downwards is the brainstem.

The white arrow points directly to the prominent, rounded blue bulge located on the upper portion of the brainstem.

Step 2: Identify the highlighted structure

The brainstem is divided into three main parts from top to bottom:

1. Midbrain: The uppermost part (shaded dark grey, just above the blue region).
2. Pons: The prominent, rounded bulge on the front of the brainstem (shaded in blue).
3. Medulla oblongata: The lower part of the brainstem below the bulge (shaded in green/yellow), which connects directly to the spinal cord.

Since the arrow points to the blue, rounded bulge on the brainstem, this structure is the Pons.

Answer:

Pons
