Question 1 1/1
List the 2 major divisions of the nervous system and the structures
found in each.
Your Answer:
CNS which contains the brain and the spinal cord
peripheral nervous system which contains spinal nerves, cranial
nerves and ganglia that are the outside of the peripheral nervous.
, The 2 divisions of the nervous system are the central
nervous system (CNS) containing the brain and spinal cord
and the peripheral nervous system (PNS) containing spinal
nerves, cranial nerves, and ganglia that are outside of the
PNS.
Question 2 1/1
pts
Describe the meninges and their function.
Your Answer:
the meninges are connective tissue sheets that are surround the brain
and the spinal cord. the Pia mater is the innermost layer of the most
meninges. it is thin and delicate and contains surface level blood vessel
that perfuse the brain and the spinal cord, the second layer of the
meninges is the arachnid layer. it encases the entire CNS and it
delicate nonvascular and waterproof. cerebrospinal fluid circulate in
Andrea just below the arachnoid layer called the subarachnoid space.
the third layer of the meninges is know as the dura mater. the dura
mater is the a strong continues connective tissue sheath that provides
the brain and the spinal cord with most of its protection.

arachnoid layer. It encases the entire CNS and is delicate,
nonvascular, and waterproof. Cerebrospinal fluid (CSF)
circulates in an area just below the arachnoid layer called
the subarachnoid space. The third layer of the meninges is
known as the dura mater. The dura mater is a strong,
continuous connective tissue sheath that provides the brain
and spinal cord with most of its protection.
Question 3 1/1
pts
Describe how CSF is produced and its function.
Your Answer:
CFS serves as a cushion for the brain and the spinal cord, protecting
them from the outside physical force. it maintain a constant ionic
environment that allow for the diffusion of essential nutrient, electrolyte ,
and metabolic waste product into the extracellular fluid surrounding the
CNS neurons. A thin layer of neuroglia cells, collective know as the
ependyma, line the ventricles of therein and the central canal of the
spinal cord.specialized ependymal cells called the chord plexus project
into the ventricles and produce CSF.
