• Thalamus (थैलेमस) — Major coordinating centre for sensory and motor signalling.
• Hypothalamus (हाइपोथैलेमस) — Controls body temperature, hunger, thirst; neurosecretory cells.
• Pituitary (पीयूष ग्रंथि) — Endocrine gland hanging from the hypothalamus.
• Midbrain (मध्य मस्तिष्क) — Cerebral aqueduct passes through; corpora quadrigemina dorsally.
• Pons (पोंस) — Fibre tracts interconnecting different brain regions.
• Cerebellum (अनुमस्तिष्क) — Highly convoluted; space for many neurons; balance and coordination.
