Answer :
Final answer:
The branches of L1 ventral ramus include the anterior rami and the genitofemoral nerve. The anterior rami supply muscles of the abdomen and thorax, while the genitofemoral nerve innervates the genital region and the front of the thigh.
Explanation:
The ventral rami of L1 spinal nerves give rise to two branches: the anterior rami and the genitofemoral nerve.
The anterior rami of the L1 spinal nerves continue as intercostal nerves, which supply the muscles of the abdomen and thorax. They also contribute to the formation of plexuses, such as the lumbar plexus.
The genitofemoral nerve is a smaller branch that innervates the genital region and the front of the thigh.
