14.02 Functions of Cerebrospinal Fluid
In order to offer the brain and spinal cord mechanical protection, the cerebrospinal fluid buoys the brain so that it
"floats" in the cranial cavity
Name the functions that the cerebrospinal fluid has in helping to maintain homeostasis
1. mechanical protection 2. chemical protection 3. circulation
In order to offer the brain and spinal cord mechanical protection, the cerebrospinal fluid prevents them from
hitting the bony walls of the cranial cavity and vertebral canal during jolts
In order to offer the brain and spinal cord the function of circulation, the cerebrospinal fluid is a medium for
minor exchange of nutrients and waste products between the blood and adjacent nervous tissue
In order to offer the brain and spinal cord chemical protection, the cerebrospinal fluid
provides an optimal chemical environment for accurate neuronal signaling
Even slight changes in the ionic composition of the cerebrospinal fluid within the brain can
seriously disrupt production of action potentials and postsynaptic potentials
In order to offer the brain and spinal cord mechanical protection, the cerebrospinal fluid serves as a
shock-absorber that protects the delicate tissues from jolts
