Options

A. Fore brain
B. Mid brain
C. Hind brain
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where Arbor vitae is found in the brain. Arbor vitae is a specific structure, and we need to identify its location.

2. **Definition of Arbor Vitae**: Arbor vitae, which translates to "tree of life," refers to the white matter in the brain that has a tree-like branching structure. It is primarily associated with the cerebellum.

3. **Analyzing the Options**:
- **Option 1: Forebrain**: The forebrain includes structures such as the cerebrum, thalamus, hypothalamus, and limbic system. Arbor vitae is not found here.
- **Option 2: Midbrain**: The midbrain consists of parts like the colliculi and tegmentum. Arbor vitae is not located in the midbrain.
- **Option 3: Hindbrain**: The hindbrain includes the cerebellum, which is where Arbor vitae is located. This is the correct answer.
- **Option 4: All of the Above**: Since only the hindbrain contains Arbor vitae, this option is incorrect.

4. **Conclusion**: Based on the analysis, the correct answer is that Arbor vitae is found in the hindbrain, specifically in the cerebellum.

**Final Answer**: Arbor vitae are found in the hindbrain.
