Solved Label the Brain A A B B Gyrus of the Cerebrum | Chegg.com - Free Printable

Thank you for uploading the image. You’ve provided a sagittal (side-view) diagram of the human brain with labeled lines (A–N) pointing to various structures, and a list of brain regions on the left that need to be matched to those labels.

Let’s solve this step by step using anatomical knowledge of the brain in sagittal section.

Step 1: Identify Key Landmarks

In a sagittal view of the brain:

- Cerebrum is the large, folded structure at the top.
- Cerebellum is the smaller, highly folded structure at the back/bottom.
- Brainstem connects cerebrum to spinal cord — includes midbrain, pons, medulla oblongata.
- Corpus callosum is the thick band connecting the two cerebral hemispheres.
- Thalamus and hypothalamus are deep brain structures near the center.
- Pituitary gland hangs below the hypothalamus.
- Gyri and sulci form the surface folds — “gyrus” = ridge, “sulcus” = groove.
- Lobes: Frontal, parietal, occipital, temporal (though temporal lobe isn’t clearly labeled here).

Step 2: Match Labels A–N to Structures

Let’s go label by label:

#### A → Frontal Lobe
- The anterior (front) part of the cerebrum.
- Label A points to the front-most region of the cerebral cortex.

✔ A = Frontal Lobe

---

#### B → Gyrus of the Cerebrum *(already given)*
- This is correct as written — B points to one of the ridges (gyri) on the surface of the cerebrum.

✔ B = Gyrus of the Cerebrum (confirmed)

---

#### C → Corpus Callosum
- The large, C-shaped white matter tract connecting the two hemispheres.
- C points directly to this structure.

✔ C = Corpus Callosum

---

#### D → Parietal Lobe
- Located behind the frontal lobe, above the temporal lobe.
- D points to the upper middle part of the cerebrum.

✔ D = Parietal Lobe

---

#### E → Occipital Lobe
- Posterior (back) part of the cerebrum.
- E points to the rearmost portion of the cerebrum.

✔ E = Occipital Lobe

---

#### F → Thalamus
- Deep brain structure, sits above the hypothalamus, relays sensory info.
- F points to the oval-shaped structure just above the pituitary/hypothalamus area.

✔ F = Thalamus

---

#### G → Hypothalamus
- Located just below the thalamus, controls autonomic functions and pituitary.
- G points to the small structure beneath the thalamus.

✔ G = Hypothalamus

---

#### H → Pituitary Gland
- Hangs from the hypothalamus via the pituitary stalk.
- H points to the small gland at the base of the brain.

✔ H = Pituitary Gland

---

#### J → Midbrain
- Part of the brainstem, located between diencephalon (thalamus/hypothalamus) and pons.
- J points to the uppermost part of the brainstem.

✔ J = Midbrain

---

#### K → Medulla Oblongata
- Lowest part of the brainstem, continuous with spinal cord.
- K points to the very bottom of the brainstem.

✔ K = Medulla Oblongata

---

#### L → Cerebellum
- The wrinkled structure at the back and bottom of the brain.
- L points to the main body of the cerebellum.

✔ L = Cerebellum

---

#### M → Transverse Fissure *(already given)*
- Separates the cerebrum from the cerebellum.
- M points to the horizontal fissure between them.

✔ M = Transverse Fissure (confirmed)

---

#### N → Pons
- Bulging structure of the brainstem, between midbrain and medulla.
- N points to the rounded bulge in the brainstem.

✔ N = Pons

---

Final Matching Table:

| Label | Structure |
|-------|-------------------------|
| A | Frontal Lobe |
| B | Gyrus of the Cerebrum |
| C | Corpus Callosum |
| D | Parietal Lobe |
| E | Occipital Lobe |
| F | Thalamus |
| G | Hypothalamus |
| H | Pituitary Gland |
| J | Midbrain |
| K | Medulla Oblongata |
| L | Cerebellum |
| M | Transverse Fissure |
| N | Pons |

*(Note: I skipped "I" because it’s not used in the diagram — likely a typo or unused label.)*

✔ Completed Answer:

Here’s how you should fill in the right-hand column (A–N):

```
A → Frontal Lobe
B → Gyrus Of The Cerebrum
C → Corpus Callosum
D → Parietal Lobe
E → Occipital Lobe
F → Thalamus
G → Hypothalamus
H → Pituitary Gland
J → Midbrain
K → Medulla Oblongata
L → Cerebellum
M → Transverse Fissure
N → Pons
```

*(Label I is not present/used in the diagram.)*

🧠 Bonus Explanation:

This diagram shows the midsagittal section of the human brain — meaning it’s cut down the middle from front to back. It’s ideal for visualizing internal structures like the corpus callosum, thalamus, and brainstem components.

The cerebrum is divided into lobes:
- Frontal → decision-making, motor control
- Parietal → sensory processing
- Occipital → vision
- Temporal → hearing, memory (not labeled here)

The brainstem (midbrain, pons, medulla) controls vital functions like breathing, heart rate, and sleep.

The cerebellum coordinates movement and balance.

The diencephalon includes thalamus (relay station) and hypothalamus (homeostasis regulator), which connect to the pituitary gland — the “master gland” of the endocrine system.
