The spinal cord can be divided to several regions: <BR><BR>

The spinal cord can be divided to several regions; '''cervical''' ''(C1-C6)'', '''cervicothoracic''' ''(C7-T2)'', '''thoracolumbar''' ''(T3-L3)'', '''lumbosacral''' ''(L3-S2)'' and '''sacral''' ''(S3 onwards)''. Nerves originating from the spinal cord and the segmental spinal nerves innervate the limbs.  

 

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.

Nerves originating from the spinal cord and the segmental spinal nerves innervate the limbs.

 

The '''forelimb nerves''' include:

 

*Suprascapular (C5-6)

*Musculocutaneous (C5-7)

*Ulna/median (Originates from the brachial plexus, which is formed from C5-T1)

*Radial (C5-T1)

 

 

The '''hindlimb nerves''' include:

 

*Obturator (L2-4)

*Femoral (L2-4)

*Sciatic (L4-S3)

 

The sciatic nerve branches to the tibial nerve and the peroneal nerve.
