: Maintain the blood-brain barrier (BBB) and regulate the chemical environment.

Myelinate axons within the central nervous system to speed up conduction.

31 pairs of nerves that emerge from segments of the spinal cord.

Support cells that maintain the environment. Astrocytes: Form the blood-brain barrier.

: The spinal cord, medulla, pons, cerebellum, midbrain, diencephalon, and cerebral hemispheres [12]. 2. Major Brain Structures : Maintain the blood-brain barrier (BBB) and regulate

Motor control circuits, common lesions, and key nuclei (caudate, putamen, globus pallidus, substantia nigra)

The brainstem controls vital autonomic functions and houses the nuclei for cranial nerves III through XII. It consists of three structures from superior to inferior:

The primary sensory relay station of the brain. It filters and directs all sensory information (except olfaction) to corresponding cortical areas. This public link is valid for 7 days

: Auditory processing, memory (Hippocampus), and language comprehension ( Wernicke’s Area ). Occipital Lobe : Primary and secondary visual processing.

Three textbooks, 14 lecture recordings, and 200 messy handwritten flashcards littered her desk. Everything was connecting to nothing. The midbrain, pons, and medulla—she knew them as words, not as a continuous story. Every time she tried to trace the corticospinal tract, it would swerve into oblivion. She slammed the textbook shut.
