The smallest part of the brain stem consists mainly of motor and sensory nerve fibers connecting the cerebral hemispheres to the pons and cerebellum. It receives information from the ears and eyes, and it is, therefore, involved in reflexes related to these organs. The pons lies between the ...
The exterior of the brain stem consists of white matter that conducts nerve signals within the brain stem and to the spinal cord and other regions of the brain. Masses of gray matter, known as nuclei, perform the processing role of the brain stem. The reticular formation, a network of mixe...

Brain stemis the most primitive part of the brain that is essential to life. Cerebellumis basically involved in motor coordination, although studies also implicated its role in cognition. Limbic system most of the incoming sensory information (except for olfactory) goes by way of thethalamusen rou...
The brain stem connects the spinal cord to the higher-thinking centers of the brain. It consists of three structures: themedulla oblongata, thepons, and themidbrain. The medulla oblongata is continuous with the spinal cord and connects to the pons above. Both the medulla and the pons are co...
The brain stem (truncus cerebri) comprises the rhombencephalon and the mesencephalon; caudally it grades into the spinal cord while rostrally it borders the diencephalon. In all vertebrates the brain stem harbours the centres of origin and termination of
