Hypothalamus of the autonomic nervous system. It synthesizes and secretes certain neurohormones, called releasing hormones or hypothalamic hormones, and these in turn stimulate or inhibit the secretion of hormones from the pituitary gland. The hypothalamus controls body temperature, hunger, important aspects of parenting and attachment behaviours, thirst, fatigue, sleep, and circadian rhythms. The hypothalamus derives its name from Greek ὑπό, "under" and θάλαμος, thalamus. The hypothalamus is a brain structure made up of distinct nuclei as well as less anatomically distinct areas. It is found in all vertebrate nervous systems. In mammals, magnocellular neurosecretory cells in the paraventricular nucleus and the
Anatomy of the cerebellum pathway transmits signals that inform the cerebellum about the movement in progress and the upcoming movement. This helps the continuous adjustment of motor activity. The initiation of the movement is relayed to cerebellum via the corticoreticulocerebellar pathway. Those synapse ipsilaterally in the reticular formation, then via the inferior and middle peduncles into the cerebellar vermis. The motor cortex and somatosensory cortex projects onto the ipsilateral inferior and accessory olivary nuclei, then forming the olivocerebellar tract. Cortico-olivary fibers synapse bilaterally in the inferior olivary nucleus. The order is preserved in the olivocerebellar tract projections onto the ‘body maps’ in the contralateral
