===Spinal Cord===
===Spinal Cord===
The spinal cord can be divided to several regions:
:'''cervical''' ''(C1-C6)''
:'''cervicothoracic''' ''(C7-T2)''
:'''thoracolumbar''' ''(T3-L3)''
:'''lumbosacral''' ''(L3-S2)''
:'''sacral''' ''(S3 onwards)''
Nerves originating from the spinal cord and the segmental spinal nerves innervate the limbs.
<br> <br>
The '''forelimb nerves''' include the '''suprascapular''' ''(C5-6)'', the '''musculocutaneous''' ''(C5-7)'', the '''ulna/median''' (Originates from the brachial plexus, which is formed from ''C5-T1'') and the '''radial''' ''(C5-T1)''.
The '''hindlimb nerves''' include the '''obturator''' ''(L2-4)'', the '''femoral''' ''(L2-4)'' and the '''sciatic''' ''(L4-S3)''. The sciatic nerve branches to the tibial nerve and the peroneal nerve.

===Meninges===
The meninges are layers of tissue surrounding the central nervous system (CNS). Meningitis is the inflammation of these layers. Gaps and spaces between the meninges are named.
