- I: iliohypogastric nerve.
- I: ilioinguinal nerve.
- G: genitofemoral nerve.
- L: lateral femoral cutaneous nerve.

- F: femoral nerve.
- L: lumbosacral trunk.
Where would you find the lumbar plexus?
The lumbar plexus is a complex neural network formed by the lower thoracic and lumbar ventral nerve roots. They are formed where T12 to L5 exit the spinal cord via intervertebral foramina. The supply motor and sensory innervation to the lower limb and pelvic girdle.
What are the 3 branches of the lumbar plexus?
However, the main branches of the lumbar plexus can be organised into groupings relative to the psoas major muscle. These branches emerge either lateral, anterior or medial to the muscle: Lateral: Iliohypogastric nerve, ilioinguinal nerve, lateral cutaneous nerve of the thigh and femoral nerve.
What is lumbar plexus?
The lumbar plexus is an essential collection of nerves that arise from mostly the lumbar spinal cord. The term plexus refers to a “web” of nerves that is created just lateral to where T12-L5 exit the spinal cord via intervertebral foramina.

The lumbosacral plexus is formed by the anterior rami of spinal nerves L4, L5, and S1 to S4, which are branches of the lumbar plexus and sacral plexus.
Is lumbar plexus sympathetic?
The lumbar plexus is formed by the junction of the anterior primary rami of L1, L2, L3, and L4. White rami leave L1 and L2, less often L3, and rarely L4. All nerves receive gray rami from the sympathetic chain.

What nerves come from C5 and C6?
From the upper trunk C5 and C6 give rise to the nerve to the subclavius, and the suprascapular nerve, that supply the subclavius muscle, and the supra- and infraspinatus muscles, respectively.
What nerve Innervates subscapularis?
The subscapularis muscle is typically innervated by two distinct nerves, namely an upper and a lower subscapular nerve, both originating from the brachial plexus [4]. These two nerve branches cross the axillary vein dorsally to reach the subscapularis muscle [5].

Is sciatic nerve part of lumbosacral plexus?
