|
Meninges |
Membranes that surround the brain and spinal cord. Singular = Meninx |
|
|
Dura Mater |
Outer most layer, toughest and adheres to skull and arachnoid mater for brain. Adheres to spinal cord and vertebral column in spine. |
|
|
Arachnoid Membrane |
Middle layer and binds dura and pia mater together with arachnoid trabeculae. |
|
|
Pia Mater |
Closely contours brain and spinal cord. Aids in secretion of and containment of cerebrospinal fluid. |
|
|
Central Nervous System |
Division of nervous system in skull and spine |
|
|
Peripheral Nervous System
|
Division of nervous system located outside skull and spine |
|
|
Somatic Nervous System |
Part of PNS that interacts with external environment. Associated with voluntary movement. |
|
|
Autonomic Nervous System |
Involuntary nervous system. Regulates systems outside of conscious control such as digestion. |
|
|
Sympathetic Nervous System |
Autonomic motor nerves that project from the CNS in the lumbar and thoracic regions of the spinal cord. Increases energy. Fight or flight. |
|
|
Parasympatheic Nervous System |
Autonomic motor nerves that project from the brain and sacral region of the spinal cord. Decreases energy. Rest and digestion. |
|
|
Afferent Nerves |
Nerves that direct signals towards the brain such as skin telling your brain that you are cold. |
|
|
Efferent Nerves |
Nerves that direct signals away from the brain such as the brain telling the muscles to get a jacket. |
|
|
Subarachnoid Space |
Contains blood vessels and cerebrospinal fluid. |
|
|
Cerebrospinal Fluid |
Fills the subarachnoid space, central canal and cerebral ventricles. |
|
|
Central Canal |
Small central channel that runs the length of the spinal cord. |
|
|
Cerebral Ventricles |
4 Larges internal chambers of the brain. |
|
|
Blood-Brain Barrier |
Surrounds most blood vessels in the brain. Helps prevent toxins from entering the brain. |
|
|
Endothelial Cells |
Interior surface cells of vessels, tightly wrapped around cells. |
|
|
Astrocytic End-Feet |
Signals to regulate blood brain barrier. |

|
|
Sagittal Section |
Sliced down middle of hemispheres into two halves. |
|
|
Horizonal / Transverse Section |
Sliced perpendicular to the body. View from the top. |
|
|
Medial |
Sections of the brain closer to the midline. |
|
|
Lateral |
Sections of the brain closer to the side. |
|
