3. The Dura Mater
The dura mater is a thick durable membrane covering the brain and closest to the skull.
Surrounds and supports the large venous channels carrying blood from the brain toward the heart.

4. Pia Mater Thin white coating on the brain surface
Contains blood vessels that supply blood to the brain.

5. The Cerebrum The largest part of the human brain.
Associated with higher brain functions such as thought and action.
Cerebrum is divided into five lobes.
Frontal, Parietal, Occipital, Temporal, and insula.

6. The Cerebellum Also known as the “little brain”
Associated with regulation and coordination of movement, posture, and balance. Involuntary Control

7. The Brain Stem
Responsible for vital life functions such as breathing, heartbeat and blood pressure.
The brain stem is made of the midbrain, pons, and medulla oblongata.

8. Medulla Oblongata
Controls autonomic functions, such as heart rate, respiratory rate, coughing, vomiting etc.
Relays nerve signals between the brain and spinal cord

9. The pons
Involved in the motor control and sensory analysis.

10. Midbrain Relay station for auditory and visual information
Eye movement

11. Frontal Lobe Involved in our motor functions. Problem solving Memory
Language
Judgment
Impulse control
Houses our personality

12. Temporal Lobe
Associated with perception and recognition of the auditory stimuli, memory, and speech.

13. Occipital Lobe Associated with visual processing
Helps interprets what the eyes see

14. Parietal Lobe Associated with movement Orientation Recognition
Perception of the stimuli to the body
Sense of Touch
Primary Somatosensory Cortex

15. Gyri and Sulci
Gyri is the bumps, elevated ridges in the cerebral cortex as shown by the circles.
Sulci: the indentations, shallow grooves, as shown by the solid lines
Gyrus
Sulcus

16. Pre central gyrus
Located in front of the central sulcus. First Gyrus in the frontal lobe.
Voluntary movement of skeletal muscles

17. Post central gyrus
In parietal lobe first gyrus behind the central sulcus.
Receives sensory feed back from all over the body; including
From joints
And tendons
Internal Organs

18. Central Sulcus
Groove, separates frontal and parietal lobes.

19. Longitudinal Cerebral Fissure
Separates the two sides of the cerebrum

20. Diencephalon
Thalamus
Hypothalamus

21. Thalamus
Processes and relays movement and sensory information

22. Hypothalamus Controlling hunger and thirst Emotions
Body Temperature regulation
Circadian rhythms
Other Homeostatic Controls. Read in your book about this little but important part of the brain.

23. Corpus Callosum Communication between the left and right hemispheres
Forms roof of lateral and third ventricles
Myelinated White Matter

24. White Matter Area where messages pass through
Develops throughout life.
Myelinated

25. Grey Matter Muscle Control Sensory Perception Seeing Hearing Memory
Speech
Emotions
