$$
\textbf{Step 1. Recognize the Structure Described}
$$  
The statement “extends through the hindbrain, midbrain, and forebrain” is typically used to describe a structure that spans all the major regions of the brain. One such structure is the $$\textbf{ventricular system}$$: the lateral ventricles are in the forebrain, the third ventricle lies in the diencephalon (part of the forebrain), the cerebral aqueduct runs through the midbrain, and the fourth ventricle is found in the hindbrain.

$$
\textbf{Step 2. Analyze the Given Options}
$$  
The options provided are:  
1) $$\text{cerebellum}$$  
2) $$\text{medulla}$$  
3) $$\text{pons}$$

$$
\text{- Cerebellum:}\quad \text{This is a structure located in the hindbrain and does not extend into the midbrain or forebrain.}
$$
$$
\text{- Medulla:}\quad \text{The medulla oblongata is part of the hindbrain (specifically, the lower portion of the brainstem) and does not span the midbrain or forebrain.}
$$
$$
\text{- Pons:}\quad \text{The pons is also part of the hindbrain, located just above the medulla, and does not extend into the midbrain or forebrain.}
$$

$$
\textbf{Step 3. Conclusion}
$$  
None of the options provided ($$\text{cerebellum}$$, $$\text{medulla}$$, or $$\text{pons}$$) correctly describe the structure that “extends through the hindbrain, midbrain, and forebrain.” The structure that meets that description is the $$\textbf{ventricular system}$$, which is not listed among the options.

$$
\textbf{Final Answer: None of the above.}
$$
None of the options provided correctly describe the structure that extends through the hindbrain, midbrain, and forebrain. The correct answer is the ventricular system, which is not listed among the choices.
