Study Notes
Overview of Brain Anatomy
- Cerebrum: The largest part, surrounding other structures. Controls perception, thought, memory, emotions, and most conscious motor activity.
- Diencephalon: Located within the cerebrum, like a peanut in a shell. Connects the brainstem and cerebrum, performing many relay and homeostatic functions.
- Brainstem: Continues from the diencephalon to the spinal cord. Composed of medulla oblongata, pons, and midbrain. Contains scattered reticular formation. Controls numerous brainstem activities, including motor control, perception, and rhythmic contractions (e.g., sleep-wake cycle).
- Cerebellum: Located behind the brainstem; involved in controlling muscle movement, tone, coordination, and balance, and in learning motor skills.
Brainstem Details
- Structure and Cross-Section: The brainstem has gray matter inside and white matter outside, similarly to the spinal cord.
