|
|
|
Four Lobes of the Brain
|
Frontal, Parietal, Temporal, Occipital
|
|
|
Diencephalon - Thalamus
|
Mood, General body movements, senses except smell

Meninges
|
surround brain and spinal cord - a set of tree tough membranes that enclose the entire CNS

|
|
P A D
For Protections |
Piamater - innermost
Arachnoid - second layer Durameter - outer, toughest |

|
|
Spinal Cord
|
at base of brain, composed of bundles of nerve fibers, extends to level of 2nd lumbar vertebra, foramen magnum, cauda equina, vertebral canal, tracts (pathways that contain nerve fibers)
|
|
|
CSF - cerebral spinal fluid
|
For protection, nutrients to internal nervous system structures, regulates ion concentration, pathway for waste products back into the blood
