|
Parts of nervous system |
Central NS peripheral NS automatic NS |
|
Central NS |
Brain and spinal cord |
|
Peripheral NS |
Includes cranial and spinal nerves and ANS(autonomic NS) |
|
Three meningies that cover the brain and spinal cord |
Duramater, arachnoid, piamater |
|
Duramater |
Outer most later of spinal cord- tough and protective |
|
Arachnoid layer |
Area where blood vessels are located |
|
Piamater |
Innermost layer and most delicate layer of the meninges (directly on top of spinal cord) |
|
Location of Cerebrospinal fluid |
In sub arachnoid space (portion of animal that is examined when brain and spinal cord problems are suspected) |
|
Cerebrospinal fluid function |
Bathe and nourish cells within the brain and SC (line of communication) |
|
Duramater Eepidur |
Outermost covering-tough and fibrous |
|
Epidural space |
Fat filled space that separates the periosteum of the vertebrae |
|
Subdural space |
Space between duramater and arachnoid |
|
Arachnoid |
Delicate membrane between the duramater and piamater |
|
Piamater |
Deepest membrane which is loosely attached to the brain and SC |
|
