Step-by-step solution for: Brain Label (Remote)
To solve this brain anatomy labeling task, we’ll go step by step through the major structures shown in the sagittal (side) view of the human brain. We’ll match each label from the list to its correct location based on standard anatomical positions.
---
Step 1: Identify the largest and most obvious structures
- The Corpus Callosum is the thick band of nerve fibers connecting the two cerebral hemispheres — it’s the big C-shaped white structure near the top center.
→ Label the large curved white structure at the top middle as Corpus Callosum.
- The Fornix is a smaller C-shaped bundle just below the corpus callosum — looks like a little arch under it.
→ Label the small arch beneath the corpus callosum as Fornix.
- The Thalamus is the large oval gray mass in the center, above the midbrain and below the corpus callosum/fornix.
→ Label the central oval structure as Thalamus.
---
Step 2: Look at the back/top part of the brain
- The Pineal Body (or pineal gland) is a tiny pea-sized structure sitting on top of the midbrain, behind the thalamus.
→ Label the small bump on top of the midbrain area as Pineal Body.
*(Note: “Pineal Body” appears twice in the list — probably a typo. We only need to use it once.)*
---
Step 3: Midbrain and surrounding areas
- The Midbrain is the stalk-like structure below the thalamus and pineal body, leading down toward the pons.
→ Label the upper part of the brainstem (just below thalamus) as Midbrain.
- The Superior Colliculus and Inferior Colliculus are bumps on the back of the midbrain — superior is higher, inferior is lower.
→ Label the upper bump on the back of midbrain as Superior Colliculus.
→ Label the lower bump on the back of midbrain as Inferior Colliculus.
---
Step 4: Brainstem downward
- The Pons is the bulging part of the brainstem below the midbrain.
→ Label the rounded bulge below midbrain as Pons.
- The Medulla (medulla oblongata) is below the pons, tapering into the spinal cord.
→ Label the section below pons as Medulla.
- The Spinal Cord continues downward from the medulla.
→ Label the very bottom extension as Spinal Cord.
---
Step 5: Front/bottom front structures
- The Pituitary gland hangs down from the hypothalamus (which isn’t labeled), located near the base of the brain, in front of the midbrain/pons junction.
→ Label the small hanging gland near the front base as Pituitary.
---
Step 6: Back/lower back structures
- The Cerebellum is the large, folded structure at the back and bottom of the brain, behind the brainstem.
→ Label the big wrinkled structure at the rear as Cerebellum.

Step 7: Remaining labels
We’ve used:
- Corpus Callosum ✔
- Fornix ✔
- Thalamus ✔
- Pineal Body ✔ (used once)
- Superior Colliculus ✔
- Inferior Colliculus ✔
- Cerebellum ✔
- Pituitary ✔
- Midbrain ✔
- Pons ✔
- Medulla ✔
- Spinal Cord ✔
Leftover: One extra “Pineal Body” — ignore it (duplicate).
Now assign them to the blank boxes in the diagram. Since you’re dragging labels, here’s how they should be placed from top to bottom, left to right roughly:
Top row (left to right):
- Leftmost top box → Corpus Callosum
- Next to it → Fornix
- Center top → Thalamus
- Right top → Pineal Body
Middle-left:
- Box pointing to back of midbrain → Superior Colliculus
- Below that → Inferior Colliculus
Front/base:
- Box near front base → Pituitary
Brainstem:
- Upper brainstem → Midbrain
- Bulge below → Pons
- Tapering part → Medulla
- Bottom tip → Spinal Cord
Back/rear:
- Large rear structure → Cerebellum
*(Note: Some diagrams may have slight variations, but these are standard placements.)*
---
Final Answer:
Drag the labels to these locations:
- Top center curved white structure → Corpus Callosum
- Small arch under it → Fornix
- Central oval mass → Thalamus
- Tiny bump on top of midbrain → Pineal Body
- Upper bump on back of midbrain → Superior Colliculus
- Lower bump on back of midbrain → Inferior Colliculus
- Hanging gland at front base → Pituitary
- Stalk below thalamus → Midbrain
- Bulging part below midbrain → Pons
- Tapering part below pons → Medulla
- Very bottom extension → Spinal Cord
- Large folded structure at back → Cerebellum
*(Ignore duplicate “Pineal Body” — use only one.)*
