Study Notes
Hind Brain
- Located at the base and back of the brain
- Contains the medulla oblongata and cerebellum
-
Medulla oblongata
- Found at the bottom of the brainstem
- Responsible for relaying information between the spinal cord and the brain
- Controls vital functions like breathing and heart rate
-
Cerebellum
- A convoluted structure located at the back of the brain
- Plays a crucial role in maintaining balance and judging distances
- Situated beneath the cerebrum
Mid Brain
- Contains the reticular formation
-
Reticular formation
- A network of nuclei distributed throughout the brainstem
- Involved in regulating the sleep-wake cycle
- Helps maintain wakefulness and alertness
Fore Brain
- Includes the hypothalamus, thalamus, and cerebrum
-
Hypothalamus
- Located above the thalamus
- Influences basic drives such as eating, body temperature, and sexual behavior
- Controls the release of hormones from the pituitary gland
-
Thalamus
- A double-lobed structure positioned above the brainstem
- Receives sensory information (except smell)
- Transmits this information to the cerebral cortex
-
Cerebrum
- Divided into two cerebral hemispheres
- Responsible for higher-order cognitive processes such as language, memory, and reasoning
