The brainstem sits between large organs -- the brain (including cerebrum and cerebellum) and spinal cord -- and is directly connected to them. The three segments of the brainstem (the midbrain, pons, and medulla) also give rise to most of the twelve cranial nerves (excluding cranial nerves I, II, and arguably XI).
The foramen magnum is the large opening at the inferior portion of the occipital bone that allows the spinal cord to connect with the brain. It acts as a passageway for the brainstem and spinal cord to communicate.
Basically what it does is protect the brain structure.
The floor of the midbrain consists of the cerebral peduncles, which are large bundles of nerve fiber tracts that connect the cerebral cortex to the brainstem. These structures are involved in motor functions and serve as a pathway for information to travel between different regions of the brain.
Human Brains are similair in structure to a sheeps brain, sheep have larger olfactory bulbs though, sheeps brains are also not a large as humans.
The structure responsible for the restriction of movement of large complex substances into the bloodstream is the endothelial cells that line blood vessels. These cells form a barrier known as the blood-brain barrier, which regulates the entry of substances from the bloodstream into the brain and spinal cord to protect the central nervous system.
The highest brain to body ratio among large animals is that of the horse, with a ratio of 1.6. Not far behind is the elephant at 1.56, then the lion at 1.55.

The medulla oblongata is the part of the brain that controls autonomic functions. Some of the functions that it controls are digestion, breathing, heart function, and swallowing.
No, the diagphragm is the large muscle just under your lungs, which helps in breathing. The structure that causes hicupps when in spasm
