Dive into the essential structures of the brain, focusing on the thalamus as the critical switching station for sensory information, regulating our awareness. Explore the hypothalamus, which governs fundamental life drives, including hunger, thirst, and emotions, while also linking the nervous and endocrine systems. Learn about the pituitary gland as the master gland, the communication roles of the pons and corpus callosum, and the vital functions controlled by the medulla oblongata, such as heart rate and breathing.

The Brain Part Two
Thalamus • Switching station of the brain • Almost all sensory information passes through here • decides what we are aware of.
Hypothalamus • Basic life drives; hunger, thirst, rage, and sex • Regulates functions such as body temperature • The nervous system's link to the endocrine system
Pituitary gland • Master gland • The endocrine system’s link to the nervous system

Pons • Communication pathway between the cerebrum and cerebellum
Pineal Gland • Light sensitive • closely related to emotions
Midbrain • Aids in hearing and sight
Corpus Callosum • Communication pathway between the two hemispheres of the brain (left and right)
Medulla Oblongata • Controls basic life functions; heart rate, breathing, blood pressure, etc.
