Regions of the brain
Cerebrum
Motor Areas
voluntary movements
Premotor cortex
coordinate movements between several muscle groups, process info to control actions
Broca's area
special motor speech area, involved in preparation to speak

Basal nuclei
involved in control of movement, cognition, and emotion
-
Hypothalamus
important for maintaining internal balance (homeostasis), main visceral control center of body
Epithalamus
connects the limbic system to other parts of the brain, secretion of melatonin and other hormones from pituitary gland by the pineal gland, regulation of motor pathways and emotions
Thalamus
relay station for incoming information into cerebral cortex, information is sorted out and edited
Pons
Located between the midbrain and medulla.
Contains conduction tracts for sensory and motor nerves.
Medulla Oblongata
Located below the pons and right before the brain stem.
Helps maintain homeostasis. Adjusts force and rate of heart contraction to meet body's needs. Adjusts blood vessel diameter to regulate blood pressure. Generates respiratory rhythm and controls the rate of breathing. Also regulates vomiting, hiccuping, swallowing, coughing, and sneezing.
Midbrain
Located above the pons.
Superior colliculi: visual reflex center. coordinates head and eye movement when following a moving object.
Inferior colliculi: relay from hearing receptors to the sensory cortex and it acts in hearing reflexes.
Cerebellum
Process information from cerebral motor cortex, proprioceptors and visual and equilibrium pathways
Provides instructions to cerebral motor cortex and subcortical motor centers, resulting in smooth, coordinated skeletal muscle movements
