    Study Notes

    Bony Structure of Abdomen and Pelvis

    • The bony structure of the abdomen and pelvis consists of the vertebral column, ribs, sternum, and pelvis.

    Pelvis

    • The posterior wall of the pelvis is formed by the sacrum, which develops from the fused ribs of S1-S5.
    • The sacrum forms the Y-shaped junction in the hip bone.

    Spinal Nerve

    • The ventral root of the spinal nerve exits through the anterior ramus.

    Ilium

    • The superior margin of the ilium is called the iliac crest.

    Thigh Muscles

    • The muscle NOT part of the anterior compartment of the thigh is the Hamstring.
    • The blood supply to the anterior compartment of the thigh comes from the femoral artery.

    Quadriceps Femoris Muscle

    • The Quadriceps femoris muscle extends the knee joint.

    Saphenous Opening

    • The saphenous opening is located in the femoral triangle.

    Femoral Nerve

    • The femoral nerve supplies the skin and muscles of the anterior compartment of the thigh.
