Central Nervous System
Meninges- Comprised of three layers of connective tissue membranes which surround and protect the
CNS (brain and spinal cord). It ensures that the brain is not in direct contact with overlying bone of skull.
Dura MaterHard Mother. Its an outermost membrane closest to the skull; Tough, inelastic
consistency
Arachnoid Mater“Web-like Mother
Subarachnoid space- Space between the arachnoid and pia mater, filled with cerebrospinal fluid
Pia materGentle Mother
subdural hemmorhage/hematoma, a dangerous condition that increases cranial pressure and damages
brain tissue. Caused by the rupturing o f blood vessels.
vs subarachnoid hemmorhage.
Blood Brain Barrier is a specialized system of capillary endothelial cells.Endothelial cells are different
from those found in peripheral tissues, allowing it to serve as a barrier to the brain
The structure of the nervous system will tell us about brain function.
There are Similarities in rat and human brain.
Dorsal view, Midsaggital view and Ventral view.
The rostral region is the Cerebrum . Hemispheres are separated by a deep SAGITTTAL FISSURE .
Cerebrum is :
Largest part of the brain
Clearly split down the middle into two cerebral hemispheres
Contralateral innervation
Everyone has a similar general pattern
Bumps: gyri and Grooves: sulci & fissures
Used to separate portion of the brain into lobes

Meninges- comprised of three layers of connective tissue membranes which surround and protect the. It ensures that the brain is not in direct contact with overlying bone of skull. It"s an outermost membrane closest to the skull; tough, inelastic consistency. Subarachnoid space- space between the arachnoid and pia mater, filled with cerebrospinal fluid. Pia mater gentle mother subdural hemmorhage/hematoma, a dangerous condition that increases cranial pressure and damages brain tissue. Caused by the rupturing o f blood vessels. vs subarachnoid hemmorhage. Blood brain barrier is a specialized system of capillary endothelial cells. endothelial cells are different from those found in peripheral tissues, allowing it to serve as a barrier to the brain.
