1. fore brain STRUCTURE

2. FOREBRAIN TELENCEPHALON DIENCEPHALON C EREBRAL CORTEX LIMBIC SYSTEM BASAL GANGLIA THALAMUS HYPOTHALAMUS

3. Cerebral cortex PRIMARY MOTOR CORTEX –region of the posterior frontal lobe involved in movement. PRIMARY SOMATOSENSORY CORTEX -located caudal to the central sulcus.Receives information from the body senses PRIMARY AUDITORY CORTEX -Located on the upper surface of the lateral fissure which receives auditory information. PRIMARY VISUAL CORTEX -Located at the back of the brain.Receives visual information The outer layer of the cerebral hemispheres

4. Limbic System HIPPOCAMPUS -Forebrain structure of the temporal lobe AMYGDALA -Interior of the rostral temporal lobe FORNIX -is a bundle of axons that connects the hippocampus with other regions of the brain

5. Basal ganglia Basal ganglia is located beneath the anterior portion of the lateral ventricles Caudate nucleus is a tail like nucleus that extends in each hemisphere from the amygdala Putamen is located in each hemisphere just lateral to the globus pallidus Globus Pallidus is located between the thalamus & putamen

6. Diencephalon IT’S THE SECOND MAJOR DIVISION OF THE FOREBRAIN Thalamus - situated near the middle of the cerebral hemisphere,makes up the dorsal part of diencephalon Hypothalamus - lies at the base of the brain under the thalamus

7. PITUITARY GLAND

9. CEREBRUM-VENTRAL VIEW

10. CORPUS CALLOSUM- egion connecting the two cerebral hemispheres CINGULATE GYRUS- Just above the corpus callosum

11. Cerebrum

12. Gyrus And Sulcus Regions

13. Four lobes of the brain STRUCTURE FRONTAL LOBE -includes everything in front of central sulcus PARIETAL LOBE -located on the side of the cerebral hemisphere just behind the central sulcus TEMPORAL LOBE -juts forward from the base of the brain OCCIPITAL LOBE -lies at the very back of the brain.caudal to the parietal and temporal lobes

14. Parts of Frontal Lobe

15. PARIETAL LOBE

16. OCCIPITAL LOBE
