Study Notes

Brain Anatomy Terms

Cerebrum: The largest part of the brain, responsible for higher brain functions, including thought and action. Divided into left and right hemispheres.
Gyri: Raised folds or ridges on the surface of the brain, increasing the brain's surface area and enhancing its cognitive abilities.
Sulci: Grooves between the gyri on the brain's surface, helping to delineate different areas of the brain.
Corpus Callosum: A thick band of nerve fibers that connects the left and right cerebral hemispheres, facilitating interhemispheric communication.
Pituitary Gland: Known as the 'master gland,' it regulates various hormonal functions in the body and is part of the endocrine system.
Brain Stem: Connects the brain to the spinal cord and controls basic life functions such as breathing, heart rate, and blood pressure.
Midbrain: Located in the brainstem, it plays a crucial role in vision, hearing, and motor control.
Pons: A section of the brainstem that acts as a bridge between different parts of the nervous system, important for regulating sleep and arousal.
Medulla Oblongata: The lower part of the brainstem; responsible for autonomic functions like heartbeat and respiration.
Spinal Cord: A long, thin bundle of nervous tissue extending from the brainstem down the vertebral column, responsible for transmitting signals between the brain and the rest of the body.
4th Ventricle: A fluid-filled cavity in the brain located between the brainstem and the cerebellum; involved in the production and circulation of cerebrospinal fluid.
Cerebellum: Positioned at the back of the brain, it plays a crucial role in motor control, coordination, and balance.
Arbor Vitae: The tree-like appearance of white matter in the cerebellum, essential for transmitting information from the cerebellum to the rest of the brain.
Pineal Gland: A small endocrine gland located near the center of the brain, responsible for producing melatonin, which regulates sleep-wake cycles.
Cerebral Aqueduct: A narrow channel connecting the 3rd and 4th ventricles in the brain, allowing the flow of cerebrospinal fluid.
Lateral Ventricle: A pair of large cavities in the brain that contain cerebrospinal fluid, contributing to nutrient transport and waste removal.
Thalamus: Acts as a relay station for sensory information, directing it to appropriate areas of the brain for processing.
Hypothalamus: A small but crucial area that regulates essential functions such as temperature control, thirst, hunger, and circadian rhythms.
Diencephalon: A region of the brain that includes the thalamus and hypothalamus, functioning as a hub for sensory and autonomic pathway processing.
