A- brain, hypo campus , maintain
B- blood brain , Capillaries , Lower
C- blood brain, capillaries, regulate
C- The BLOOD-BRAIN barrier is produced by tightly packed cells in the CAPPILARIES of the brain. it helps to REGULATE the chemical balance of the brain.
How does the way the brain gets molecules such as oxygen and carbon dioxide compare with how it obtains glucose and amino acids?
A- they are the same
b - the brain gets O2 and CO2 by passive transport of the blood brain barrier , and gets glucose by active transport
c- the brain gets O2 and CO2 by active transport systems , and glucose by the blood brain barrier
b - the brain gets O2 and CO2 by passive transport of the blood brain barrier , and gets glucose by active transport

C- only providing structure
A- acting as the ‘glue’ , providing structure and insulating nerves
What is retts syndrome ?
Retts’ syndrome is common in young girls, it causes speech impairments as well as difficulties in muscle control
The syndrome is caused by a mutation in a protein present in neurones .

B- cortex callostomy
c- corpus collom
A- a corpus callostomy , severers the corpus callosum that joins the left and right hemispheres
what is a Gyrus and a Sulcus ?
A gyrus is the ridges on the cortex
a sulcus is the indentations
