The largest branch of the sacral plexus is the sciatic nerve, the thickest and longest nerve in the body.
The nerves that arise from the lumbar plexus are femoral, obturator, lateral femoral cutaneous, genitofemoral, illoinguinal and illohypogastric nerve. As part of lumbosacral plexus, it is the nervous plexus that is found in the lumbar region.
sacral plexus
The sciatic nerve originates from the sacral plexus, specifically from the nerve roots L4 to S3. It is the largest nerve in the body and supplies the lower limb with both motor and sensory functions.
Inferior gluteal nerve
The lumbar plexus contains nerve fibers that innervate the leg, and the sacral plexus contains nerve fibers that innervate the foot. The lumbar plexus arises from the lower spinal cord levels, while the sacral plexus arises from the sacral spinal cord levels.
The sacral plexus gives rise to the sciatic nerve. It is formed by the ventral rami of spinal nerves L4-S4 and is the largest nerve in the body.
Cervical: C1 - C5Innervates muscles of neck and extend into thoracic cavity, where they control diaphragmatic muscles. Major nerve: Phrenic...which provides entire nerve supply to diaphragm.Brachial: C5-T1Innervates pectoral girdle and upper limbs. Major nerves: Radial nerve, median nerve, ulnar nerve.Lumbar: T12 - L4Innervates pelvic girdle and lower limbs. Major nerves: Genitofemoral nerve, lateral femoral cutaneous nerve, and femoral nerve.Sacral: L4-S5Innervates pelvic girdle and lower limbs. Major nerves: Sciatic nerve (which branches into tibial and fibular nerves) and pudendal nerve.
The network of spinal nerves that supplies the pelvis and legs is known as the lumbosacral plexus. It is formed by the lower lumbar and sacral spinal nerves and gives rise to various nerves that innervate the lower extremities, including the sciatic nerve, femoral nerve, and obturator nerve. These nerves play a crucial role in motor and sensory functions of the pelvis and legs.

No, the sciatic nerve is not located in the brachial plexus. The sciatic nerve is a large nerve that originates in the lower back and runs down the back of each leg, while the brachial plexus is a network of nerves in the shoulder region that innervates the upper limb.
Sciatic Nerve The Largest nerve in human body. A sensory and motor nerve originating in the sacral plexus and running through the pelvis and upper leg.
