Q: What structures does the brainstem connect?

Q: Where is most gray matter located in the brainstem?

A: On the inside, with white matter more external but mixed.

Q: What are long tracts, and where do they run?

A: Motor and sensory axons running between cerebrum and spinal cord via brainstem.

Q: What functions are primarily handled by cranial nerves from the brainstem?

A: Motor, sensory, and autonomic control of head and neck.

Q: What role does the reticular formation play?

A: Regulates autonomic functions and supports consciousness via cerebral projections.
