What nerve controls quadriceps muscle group?
Femoral nerve
What are some parts of the frog's nervous system?

What nerve is tested for patellar reflex?
The Femoral nerve. Wikipedia: Striking the patellar tendon with a tendon hammer just below the patella stretches the quadriceps muscles in the thigh. This stimulates stretch sensory receptors (i.e. muscle spindles) to trigger an afferent impulse in a sensory Ia-nerve fiber of the femoral nerve which synapses (without interneurones) at the level of L4 in the spinal cord, completely independent of higher centres.
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.
Afferent nerve fibers enter the part of the spinal cord called?
gray commissure
Which nerve plexus contains the femoral nerve?
The lumbar plexus
What structure pass through the adductor subsartorial canal?
femoral artery and femoral vein, saphenous nerve and nerve to vastus medialis
What contains the cranial nerve and spinal nerve?
Spinal Accessory Nerve
Why femoral nerve lies outside from femoral triangle?
The femoral sheath is a downward prolongation of abdominal fascial lining into the lower limbs. It covers the femoral vessels and lymphatics for about 1.5 inches into the thigh. But the femoral nerve, which is the principal nerve of lower limb, lies outside this sheath. The reason is that the major nerves lie outside the fascial envelope.
What does the femur protect?
The femur protects the deep femoral artery as well as the femoral nerve.
Can you have pain in leg if you have back pain?
The short answer is No (although you may have pain on the front side of your thigh from the "femoral or subcutaneous femoral nerve" (or othter spinal nerves). You may also feel "referred" pain, in the lower front portion of your leg from another spinal nerve (such as L3-4). The longer answer simply involves knowing where the sciatic nerve runs. Taken from another answer : The sciatic nerve is the largest and longest nerve in the body. About the thickness of a person's thumb, it spans from the lower back to the foot. The nerve originates in the lower part of the spinal cord, the so-called lumbar region. As it branches off from the spinal cord, it passes between the bony vertebrae (the component bones of the spine) and runs through the pelvic girdle, or hip bones. The nerve passes through the hip joint and continues down the B A C K of the leg to the foot.
What are the 31 spinal nerves called?
The proper name is Mixed Spinal Nerve.They do not have individual names, however. They are referred to by their number, with number one just above the first rib and the 31st going through the foramen between sacral 4 & 5.
