The ilioinguinal nerve is a branch of the first lumbar nerve (L1). It separates from the first lumbar nerve along with the larger iliohypogastric nerve . It emerges from the lateral border of the psoas major just inferior to the iliohypogastric , and passes obliquely across the quadratus lumborum and iliacus .
The only cardiac nerves which do not enter into the formation of the deep part of the cardiac plexus are the superior cardiac nerve of the left sympathetic trunk, and the lower of the two superior cervical cardiac branches from the left vagus nerve, which pass to the superficial part of the plexus.
The heart is both the source of life and a source of cardiac arrhythmias and complications. The information originates in the brain's cortex and descends down to the hypothalamus . The neural signals are then transferred to the brainstem , followed by the spinal cord —the location from which the heart receives all its signals.
The lateral cutaneous branch ("iliac branch") pierces the internal oblique muscles and the external oblique muscles immediately above the iliac crest. [4] It is distributed to the skin of the gluteal region, behind the lateral cutaneous branch of the subcostal nerve; the size of this branch bears an inverse proportion to that of the lateral cutaneous branch of the subcostal nerve.
The cardiac nerves are autonomic nerves which supply the heart. [1] They include: Superior cardiac nerve [1] (nervus cardiacus cervicalis superior) Middle cardiac nerve [1] (nervus cardiacus cervicalis medius) Inferior cardiac nerve [1] (nervus cardiacus inferior)
The anterior scrotal nerves are branches of the ilioinguinal nerve. The nerves innervates the scrotum in males. The equivalent nerves in the female are the anterior labial nerves .
