What major nerves arise from the sacral?
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.
What are the four nerve plexuses?
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.
What major nerve serves the lower abdomen and anterior thigh?
femoral vein
The nerve plexus that contains neurons that are primarily concerned with regulating the motility within the GI tract is the plexus?
The nerve plexus that primarily regulates the motility within the GI tract is the enteric nervous system, which includes the myenteric plexus (Auerbach's plexus) and the submucous plexus (Meissner's plexus). These plexuses coordinate the contractions of smooth muscle in the gut, controlling movements such as peristalsis and segmentation.
The median nerve is a member of which nerve plexus?
The median nerve is a member of the brachial plexus. It is formed by contributions from the lateral and medial cords of the brachial plexus, primarily from spinal nerve roots C6, C7, C8, and T1.

Which plexus contains the foot and the leg?
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 obturator and femoral nerves branch from this plexus?
cervical plexus
What action does the femoral nerve do?
Nerves do not have actions. Muscles do, but nerves go to certain receptors. The femoral nerve is the largest in the lumbar plexus and divides into many branches, and supplies the thigh muscles and leg and skin cutaneous receptors (feeling).
Which of the nerve plexuses originates from ventral rami L1 through L4?
The lumbar plexus originates from ventral rami L1-L4. It supplies nerves to the lower abdominal wall, pelvic region, and parts of the lower limb. Key nerves arising from this plexus include the femoral nerve and the obturator nerve.
What nerve controls quadriceps muscle group?
Femoral nerve
The phrenic nerve is a member of which nerve plexus?
Cervical plexus....
What major nerve serves the lower abdomen and anterior thigh?
femoral vein
The lumbosacral plexus contains a nerve that that branches to thigh muscles and ultimately the feet. What is its name?
It is known as the sciatic nerve.
