Study Notes

Coxal Region Study Notes

  • Hip Joint: The primary joint structure in the coxal region, essential for movement and weight-bearing.

Nerves

  • Femoral Nerve: Innervates the anterior compartment of the thigh, crucial for leg extension and sensation.
  • Obturator Nerve: Responsible for innervating the medial compartment of the thigh, aiding in adduction.
  • Sciatic Nerve: The largest nerve in the body, innervating the posterior compartment of the thigh and lower leg.

Bony Structures

  • Head of Femur: Articulates with the acetabulum, forming the hip joint.
  • Neck of Femur: Connects the head to the body, susceptible to fractures.
  • Body of Ischium: Part of the pelvic bone, contributing to the acetabulum.
  • Body of Pubis: Forms the anterior region of the pelvis, assisting in pelvic structure.
  • Greater Sciatic Notch: A key landmark for the passage of nerves and blood vessels from the pelvis to the lower limb.

Blood Vessels

  • External Iliac Vein: Drains blood from the lower limb back to the heart.
  • Internal Iliac Vein: Collects blood from the pelvic region.
  • Great Saphenous Vein: The longest vein in the body, important for superficial venous drainage.
  • Femoral Artery: Main artery supplying blood to the lower limb.
  • Deep Femoral Vein: Accompanies the deep femoral artery, critical for venous return.

Muscles and Actions

  • Adductor Longus: Primarily functions to adduct and flex the thigh.
  • Pectineus: Assists in thigh adduction and flexion; located in the upper thigh.
  • Gracilis: A long, thin muscle that adducts and flexes the thigh.
  • Gluteus Medius: Abducts and medially rotates the thigh, essential for stability when walking.
  • Gluteus Minimus: Similar function to gluteus medius, contributing to thigh movement and stability.
