What are the two divisions of the forebrain?

• A. Telencephalon and Diencephalon
• B. Mesencephalon and Metencephalon
• C. Myelencephalon and Spinal cord
• D. Cerebellum and Brainstem

Answer: (A)

The forebrain comes from the front part of the neural tube (the prosencephalon) and then splits into two regions: the telencephalon and the diencephalon. The telencephalon forms the cerebral hemispheres, including the cerebral cortex, basal ganglia, and limbic structures, supporting higher cognition and emotion. The diencephalon becomes the thalamus and hypothalamus (along with related structures), regulating sensory relay, consciousness, and autonomic functions. This developmental split distinguishes forebrain structures from the midbrain and hindbrain regions, which arise from other primary vesicles. So, the two divisions are the telencephalon and the diencephalon.
