Document Summary
The spinal cord is described as a rope of neural tissue that runs inside the hollows of the vertebrae from just above the pelvis and into the base of the skull. The cord is composed of two distinct tissue types: the gray matter is dominated by the cell bodies of neurons, and the white matter consists mostly of axons and the fatty sheaths. A section of the bottom of the brain that houses the most basic programs of survival; breathing, swallowing, vomiting, urination, and orgasm. It also handles a whole complement of reflexes, basic survival behaviour. It contains network of neurons known collectively as the reticular formation, that project up into the cerebral cortex and affect general arousal and sleep. The cerebellum is a large protuberance at the back of the brainstem that is essential for smooth, coordinated movement and balance. The hypothalamus is the master regulatory structure of the brain.
