Bridge information between hemispheres Forebrain-Cerebrum |
|
|
Cerebrum
|
Center of consciousness-speech, reasoning, memory, personality, and motor functions Outside is the Cerebral Cortex (grey matter) Divided into 4 lobes-Frontal, Parietal, Temporal, Ocipital Forebrain |
|
|
Frontal Lobe
|
Conscious thought Personality Muscle movement Speech(left side) -Broca's area, rough formation of words. |
|
|
Parietal Lobe

|
|
|
Brain protection
|
Bone-skull and spinal cord Spinal cord Meninges Cerebrospinal Fluid |
|
|
Spinal Cord
|
Dorsal root carries sensory neurons-back Ventral root carries motor neurons-front |
|
|
Meninges
|
Three layers of membranes Prevent direct circulation of blood Blood-brain barrier (filter out impurities) |
|
|
Cerebrospinal Fluid
|
Circulates between the meninges, and down the central spinal cordCushions, hydrates, nourishes
