Detailed explanation-1: -The brachial plexus (plexus brachialis) is a somatic nerve plexus formed by intercommunications among the ventral rami (roots) of the lower 4 cervical nerves (C5-C8) and the first thoracic nerve (T1).
Detailed explanation-2: -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.
Detailed explanation-3: -The C4 and C5 roots give rise to the dorsal scapular nerve that supplies the rhomboids and levator scapulae.
Detailed explanation-4: -From superior to inferior, the major nerves that branch off the lumbar plexus include the iliohypogastric nerve, ilioinguinal nerve, genitofemoral nerve, lateral femoral cutaneous nerve, obturator nerve, and femoral nerve, as well as the lumbosacral trunk.
