Hypothalamus : production of releasing hormones and regulation of temperature, hunger and thirst.
Limbic system : consist of fibre tracts that interconnect different regions of brain; controls movements.
Medulla oblongata : controls respiration and cardiovascular reflexes.
Corpus callosum : band of fibers connecting left and right cerebral hemispheres.
The limbic system is a collection of nuclei, tracts, and cortical areas that covers the brain and that surrounds the thalamus. The limbic system deals with three key functions: emotions, memories and arousal (or stimulation). There is no involvement in movement. Thus, the correct answer is option B.
