What major nerves serve the anterior thigh?
The major nerves that serve the anterior thigh are the femoral nerve and the obturator nerve. The femoral nerve innervates the quadriceps muscles, while the obturator nerve innervates the adductor muscles of the thigh.
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.
The obturator and femoral nerves branch from this plexus?
cervical plexus
Can a needle injected to far into the t-12 - L-1 which you know hit nerves damage the femoral nerve?
If a needle inserted too far at the T12-L1 level hits nerves, it is possible to damage the femoral nerve as it originates from the lumbar nerve roots. Symptoms of femoral nerve damage may include weakness in the thigh or difficulty walking. It is important to seek medical attention if you suspect nerve damage.
What nerve controls quadriceps muscle group?
Femoral nerve
Which nerve innervates knee extension?
OBTURATOR
Does the obturator nerve branch from the sacral plexus?
false
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.
Foramen between pubic and ischial ramus?
The obturator foramen is the opening located between the pubic and ischial rami of the pelvis. It is partially covered by the obturator membrane and serves as a passageway for the obturator nerve and vessels.
What would damage to the lumbar plexus affect?
Damage to the lumbar plexus can affect the functioning of the lower limbs by impairing the nerves that innervate the hip, thigh, and parts of the leg and foot. This may result in weakness, pain, or loss of sensation in areas such as the anterior thigh (through the femoral nerve) and the medial thigh (through the obturator nerve). Additionally, it may disrupt bladder and bowel control due to its role in autonomic functions. Overall, such damage can significantly impact mobility and quality of life.
Which are the following structures passes through the greater sciatic foramen of the llium?

What structure pass through the adductor subsartorial canal?
femoral artery and femoral vein, saphenous nerve and nerve to vastus medialis
