Definitions



Brain = the control center of
movement
Cranium = part of the skull that
directly covers the brain
Menininges = the three
protective membranes between
the brain and the cranium




Dura mater = outermost
membrane; it is the toughest
and thickest
Arachnoid = the middle layer
pia mater = inner most layer,
consists mainly of small blood
vessels and follows the
contours of the brains surface
Definitions continued


Cerebrospinal fluid = bathes
the entire brain and fills the
ventricles, protects the inner
parts of the brain from varying
pressures and transports
chemical substances around the
system
ventricles = a series of four
cavities near the brains center
Definitions continued

Each hemisphere of the brain is restricted to a
certain intellectual function. The left hemisphere is
dominant in most people
