General Sensory Systems,Ascending in the spinal cord to higher centers in the nervous system, are two particularly important pathways:

Trigeminal System,General sensation from face, oral cavity (including teeth), skin of anterior part of head, and supratentorial meninges

,Motor Systems — Pyramidal,Comprising cells and fibers of the upper motor neuron system arising from the cerebral cortex, which project without synapse, to lower motor neurons in the brainstem and spinal cord and adjacent regions.

LANCE

,Motor Systems — Extra Pyramidal or Basal Ganglia System,A widely spread system of nuclei and fiber tracts, involving cerebral cortex and numerous sub-cortical regions. In contrast to the pyramidal system, this complex motor system influences lower motor neurons via numerous neurons and synapses, involving complex feedback mechanisms.

Vestibular and Cochlear Systems,An elaborate sensory system which is concerned primarily with reflex adjustment of position of the eyes, head, neck, trunk, and extremities in response to changes in position of the head relative to gravity, and movement of the head.

The Diencephalon,The diencephalon is located at the rostral end of the brain stem. It is bounded laterally by the posterior limb of the internal capsule, and divided on the midline by the third ventricle.

Cerebrum,Comprised of a surface layer of cortical grey matter, a deep layer of subcortical white matter, and several subcortical grey matter masses embedded in the deeper portion of the white matter (the basal ganglia). Cerebro Spinal Fluid filled ventricular cavities (the lateral ventricles) occupy the central portion of each hemisphere.
