$\text{\_\_\_}$ (3) control of temperature, autonomic nervous system, hunger, and water balance

$\text{\_\_\_}$ (4) contains the substantia nigra and red nucleus

$\text{\_\_\_}$ (5) involved in visual and auditory reflexes; found in midbrain

$\text{\_\_\_}$ (6) part of diencephalon with vital centers controlling heart rate, some aspects of emotion, and blood pressure

$\text{\_\_\_}$ (7) all inputs to cerebral cortex must first synapse in one of its nuclei

$\text{\_\_\_}$ (8) brain area that has folia and coordinates movements

$\text{\_\_\_}$ (9) brain region that contains the cerebral aqueduct

$\text{\_\_\_}$ (10) associated with fourth ventricle and contains nuclei of cranial nerves V-VII
