Pyramids nerve tracts conscious control of skeletal muscle. Center for vital reflexes heart rate, blood pressure, respiration, swallowing, coughing, sneezing. Olives nuclei involved in balance, coordination, modulation of sound. Nuclei of cranial nerves viii, ix, x,xi, xii. Pontine nuclei communication between cerebrum and cerebellum. Midbrain: reflexes located between thalamus and pons sends responses to cerebral cortex. Tectum: 4 nuclei form mounds on dorsal surface of midbrain each separate part is a colliculus. Two superior colliculi (top)involved in visual reflexes. Two inferior colliculi (bottom) involved in hearing can make muscle reflexes auditory signals visual reflexes to look @ what made noise.
