|
|
Embryonic development of the brain contains the
|

|
|
Cranial Meninges are
|
connective tissue layers that surround the brain and spinal cord.
|
|
Functions of the cranial meninges are
___________, _________ and ________. |
1) separate brain from skull
2) enclose and protect blood vessels supplying brain 3) contain and circulate CSF |
|
From skull to brain
|
scalp, periosteum, bone of skull, periosteal layer, meningeal layer, subdural space, arachnoid, subarachnoid space, arachnoid trabeculae, pia mater, cerebral cortex and white matter.
|
|

|
DURA mater
|
|

|
lateral ventricles, septum pellucidum, third ventricle, mesencephalic (cerebral) aqueduct, fourth ventricle and choroid plexus
|
|
CSF is produced in the
|
choroid plexus
|
|
the choroid plexus is made up of
|
ependymal cells
|

|
CSF reduces brain weight by
|
95%
|
|
Hydrocephalus is caused by
|
obstruction of CSF flow or problems with the arachnoid villi intriscially that results in excessive CSF. BIG HEAD!
|
|
Hydrocephalus can be treated by
|
inserting ventriculoperitoneal shunt or endoscopic 3rd ventriculostomy

mylenated axons
|
|
Gyri and sulci account for the large surface area of the
|
cerebrum
|
|
The 5 lobes of the cerebrum are
|
frontal, parietal, occipital, temporal and insula
