Selected Structures and Functions
Cerebrum	controls reasoning and thinking; responsible for conscious movement
Pineal Body	endocrine gland secreting melatonin; prepares the body for sleep
Corpora Quadrigemina	control some reflex responses, such as the response to sound
Thalamus	relay area for sensory impulses passing to the cerebral cortex
Hypothalamus	controls the ANS, regulation of body temperature, water balance, thirst, and fat and carbohydrate metabolism
Corpus Callosum	major commissure connecting the cerebral hemispheres
Lateral Ventricle	fluid-filled chamber protecting the brain from trauma
Olfactory Lobe	sense of smell
Pons	consists primarily of motor and sensory fiber tracts between the brain and lower CNS centers
Medulla Oblongata	contains autonomic centers involved in the control of heart rate, respiratory rhythm, blood pressure, swallowing and vomiting
Spinal Cord	tracts of CNS fibers within the spinal column
Fourth Ventricle	chamber within the cerebellum that protects the area from trauma
Cerebellum	unconscious coordination of skeletal muscle activity and control of balance and equilibrium
Pituitary Gland	"master" endocrine gland; see description under Endocrine System
